Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization and Description of Business | Note 1. Organization and Description of Business Biora Therapeutics, Inc. (the “Company” or “Biora” or "Biora Therapeutics") is a biotechnology company developing oral biotherapeutics that could enable new treatment approaches in the delivery of therapeutics. The Company's therapeutics pipeline includes two therapeutic delivery platforms: • NAVICAP TM Targeted Oral Delivery Platform: Targeted oral delivery of therapeutics to the site of disease in the gastrointestinal tract designed to improve outcomes for patients with Inflammatory Bowel Disease; and • BIOJET TM Systemic Oral Delivery Platform: Systemic oral delivery of biotherapeutics designed to replace injections with needle-free, oral delivery of large molecules for better management of chronic diseases. Biora Therapeutics, a Delaware corporation, was formerly known as Progenity, Inc. (“Progenity”), and commenced operations in 2010 with its corporate office located in San Diego, California. The Company's historical operations included a licensed Clinical Laboratory Improvement Amendments and College of American Pathologists certified laboratory located in Michigan specializing in molecular testing markets serving women’s health providers in the obstetric, gynecological, fertility, and maternal fetal medicine specialty areas in the United States. Previously, the Company's core business was focused on the carrier screening and noninvasive prenatal test market, targeting preconception planning, and routine pregnancy management for genetic disease risk assessment. Through its former affiliation with Mattison Pathology, LLP (“Mattison”), a Texas limited liability partnership doing business as Avero Diagnostics (“Avero”), located in Lubbock and Dallas, Texas, the Company’s operations also included anatomic and molecular pathology testing products in the United States. In order to refocus efforts and resources on its research and development pipeline, in June 2021, the Company announced a strategic transformation ("Strategic Transformation") that included the closure of the Progenity genetics laboratory in Ann Arbor, Michigan, and in December 2021, the Company sold Avero, together referred to as the Laboratory Operations. The Company has excluded from continuing operations for all periods presented in this report revenues and expenses associated with its Laboratory Operations, which are reported as discontinued operations. See Note 4 for additional information on the Laboratory Operations. On April 12, 2022, the Company announced that it would rebrand to better reflect the current focus on its therapeutics pipeline, and would begin to operate as Biora Therapeutics, Inc., a Delaware corporation. The Company subsequently changed its name to Biora Therapeutics, Inc. on April 26, 2022. On December 29, 2022, the Company filed a certificate of amendment ("the Certificate of Amendment") to its eighth amended and restated certificate of incorporation to effect, as of January 3, 2023, a 1-for-25 reverse split of the Company's common stock (the "Reverse Stock Split"). On January 3, 2023, the Company effected the Reverse Stock Split. See Note 2 for additional information. Liquidity As of December 31, 2022, the Company had cash and cash equivalents of $ 30.5 million and an accumulated deficit of $ 826.8 million. For the year ended December 31, 2022, the Company reported a net loss of $ 38.2 million and cash used in operating activities of $ 64.4 million. The Company’s primary sources of capital have historically been the sale of common stock and warrants, private placements of preferred stock and the incurrence of debt. As of December 31, 2022, the Company had $ 127.8 million of convertible senior notes, net ("Convertible Notes") outstanding (see Note 8). While the Company has greatly reduced its cash burn following the Strategic Transformation, management does not expect that the Company's current cash and cash equivalents will be sufficient to fund its operations for at least 12 months from the issuance date of the consolidated financial statements for the year ended December 31, 2022, and will require additional capital to fund the Company's operations. As a result, substantial doubt exists about the Company’s ability to continue as a going concern for 12 months following the issuance date of the consolidated financial statements for the year ended December 31, 2022. The Company’s ability to continue as a going concern is dependent upon its ability to raise additional funding. Management believes that the Company’s liquidity position as of the date of this filing provides sufficient runway to achieve important research and development pipeline milestones. Management intends to raise additional capital through equity offerings and/or debt financings, or from other potential sources of liquidity, which may include new collaborations, licensing or other commercial agreements for one or more of the Company’s research programs or patent portfolios or divestitures of the Company's assets. Adequate funding, if needed, may not be available to the Company on acceptable terms, or at all. The Company’s ability to raise additional funds may be adversely impacted by potential worsening global economic conditions and the disruptions to, and volatility in, the credit and financial markets in the United States and worldwide. If the Company is unable to raise capital when needed or on attractive terms, it would be forced to delay, reduce, or eliminate its research and development programs or other operations. If any of these events occur, the Company’s ability to achieve its operational goals would be adversely affected. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Note 2. Summary of Significant Accounting Policies Basis of Presentation The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of Biora Therapeutics and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The consolidated financial statements include the accounts of Biora Therapeutics, Inc., its wholly-owned subsidiaries, and, for the year ended December 31, 2021, an affiliated professional partnership with Avero with respect to which the Company had a specific management arrangement (see Note 3). All significant intercompany balances and transactions have been eliminated in consolidation. The consolidated financial statements and notes thereto give retrospective effect to the Reverse Stock Split for all periods presented. All common stock, options exercisable for common stock, restricted stock units, warrants and per share amounts contained in the consolidated financial statements have been retrospectively adjusted to reflect the Reverse Stock Split for all periods presented. Concurrent with the Reverse Stock Split the Company effected a reduction in the number of authorized shares of common stock from 350,000,000 shares to 164,000,000 shares. Financial Statement Presentation Change In order to more closely align with the Company’s business, and to better serve financial statement users, the Company has combined selling and marketing expenses with general and administrative expenses into a single selling, general and administrative expense line item. The Company's previous marketing expenses were associated with our discontinued Laboratory Operations and the Company no longer incurs these costs. Prior period amounts have been reclassified to conform to the current presentation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates include the estimate of variable consideration in connection with the recognition of revenue, the valuation of stock options, the valuation of goodwill, the valuation of the derivative liability associated with the Convertible Notes, accrual for reimbursement claims and settlements, the valuation of warrant liabilities, the valuation of assets held for sale, assessing future tax exposure and the realization of deferred tax assets, and the useful lives and the recoverability of property and equipment. The Company bases these estimates on historical and anticipated results, trends, and various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities and recorded revenues and expenses that are not readily apparent from other sources. Actual results could differ from those estimates and assumptions. Operating Segments Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker or decision-making group in making decisions on how to allocate resources and assess performance. The Company views its operations and manages its business as one operating segment. All revenues are attributable to U.S.-based operations and all assets are held in the United States. Assets Held for Sale and Discontinued Operations Assets and liabilities are classified as held for sale when all of the following criteria for a plan of sale have been met: (1) management, having the authority to approve the action, commits to a plan to sell the assets; (2) the assets are available for immediate sale, in their present condition, subject only to terms that are usual and customary for sales of such assets; (3) an active program to locate a buyer and other actions required to complete the plan to sell the assets have been initiated; (4) the sale of the assets is probable and is expected to be completed within one year; (5) the assets are being actively marketed for a price that is reasonable in relation to their current fair value; and (6) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or the plan will be withdrawn. When all of these criteria have been met, the assets and liabilities are classified as held for sale in the consolidated balance sheet. Assets classified as held for sale are reported at the lower of their carrying value or fair value less costs to sell. Depreciation and amortization of assets ceases upon designation as held for sale. Discontinued operations comprise activities that were disposed of, discontinued or held for sale at the end of the period, represent a separate major line of business that can be clearly distinguished for operational and financial reporting purposes and represent a strategic business shift having a major effect on the Company’s operations and financial results according to Accounting Standard Codification (“ASC”) Topic 205, Presentation of Financial Statements . Additional details surrounding the Company's assets and liabilities held for sale and discontinued operations are included in Note 4 . Investments The Company accounts for investments in equity securities without a readily determinable fair value at cost, minus impairment. If the Company identifies observable price changes in orderly transactions for an identical or a similar investment of the same issuer, the Company will measure the equity security at fair value as of the date that the observable transaction occurred in accordance with ASC Topic 321, Investments-Equity Securities . Revenue Recognition Revenue is recognized in accordance with the Financial Accounting Standards Board (“FASB”) ASC Topic 606 , Revenue from Contracts with Customers (“ASC 606”). In accordance with ASC 606, the Company follows a five-step process to recognize revenues: 1) identify the contract with the customer, 2) identify the performance obligations, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations and 5) recognize revenues when the performance obligations are satisfied. Revenue was primarily derived from providing molecular testing products, which were reimbursed through arrangements with third-party payors, laboratory distribution partners, and amounts from individual patients. Third-party payors include commercial payors, such as health insurance companies, health maintenance organizations and government health benefit programs, such as Medicare and Medicaid. The Company’s contracts generally contained a single performance obligation, which was the delivery of the test results, and the Company satisfied its performance obligation at a point in time upon the delivery of the results, which then triggered the billing for the product. The amount of revenue recognized reflects the amount of consideration the Company expected to be entitled to ("transaction price") and considered the effects of variable consideration. Revenue was recognized when control of the promised product was transferred to customers, in an amount that reflected the consideration the Company expected to be entitled to in exchange for those products. The Company applies the following practical expedients and exemptions: • Incremental costs incurred to obtain a contract are expensed as incurred because the related amortization period would be one year or less. The costs are included in selling and marketing expenses. • No adjustments to amounts of promised consideration are made for the effects of a significant financing component because the Company expects, at contract inception, that the period between the transfer of a promised good or service and customer payment for that good or service will be one year or less. Payor Concentration The Company historically relied upon reimbursements from third-party government payors and private-payor insurance companies to collect accounts receivable. As a result of the Strategic Transformation, all revenue from Laboratory Operations has been classified as discontinued operations and there were no significant concentrations as of December 31, 2022. The Company’s significant third-party payors and their related accounts receivable balances and revenues as a percentage of total accounts receivable balances as of December 31, 2021 and of revenues for the year ended December 31, 2021 are as follows: Percentage of Accounts Receivable December 31, 2021 Blue Shield of Texas 4.0 % United Healthcare 7.2 % Government Health Benefits Programs 55.8 % Percentage of Revenue (1) Year Ended December 31, 2021 Blue Shield of Texas 10.7 % Aetna 7.3 % Cigna 5.7 % United Healthcare 6.7 % Government Health Benefits Programs 23.2 % (1) Percentage of revenue table shows amounts as a percentage of total revenue, including revenue classified as discontinued operations. Refer to Note 5 for details of the breakdown of revenue. Accounts Receivable Amounts included in accounts receivable for the year ended December 31, 2021 consist of receivables generated from the Company's genetics laboratory in Ann Arbor, Michigan. The Company continued to collect these receivables and did not include these amounts as assets held for sale. The accounts receivable amounts were recorded at the transaction price and considered the effects of variable consideration. The total consideration the Company expected to collect was an estimate and was fixed or variable. Variable consideration included reimbursement from third-party payors, laboratory distribution partners, and amounts from individual patients, and was adjusted for disallowed cases, discounts, and refunds using the expected value approach. The Company monitors these estimates at each reporting period based on actual cash collections in order to assess whether a revision to the estimate is require d. Cash and Cash Equivalents including Concentration of Credit Risk The Company considers all highly liquid investment instruments purchased with an initial maturity of three months or less to be cash equivalents. The Company limits its exposure to credit loss by placing its cash and cash equivalents in financial institutions with high credit ratings. The Company’s cash and cash equivalents may consist of deposits held with banks, money market funds, or other highly liquid investments that may at times exceed federally insured limits. Cash equivalents are financial instruments that potentially subject the Company to concentrations of risk, to the extent of amounts recorded in the balance sheets. The Company performs evaluations of its cash equivalents and the relative credit standing of these financial institutions and limits the amount of credit exposure with any one institution. Management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. Property and Equipment, Net Property and equipment are stated at cost. Assets acquired under capital leases are stated at the present value of future minimum lease payments. Depreciation is recognized on a straight-line basis over the estimated useful lives of the related assets as follows: Property and Equipment Estimated Useful Life (in years) Computers and software 3 Laboratory equipment 5 Furniture, fixtures, and office equipment 8 Building 15 Assets acquired under capital leases and leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or the useful life of the asset. Land is not depreciated. Leases The Company determines if an arrangement is or contains a lease at inception. For leases with a term greater than one year, lease right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the net present value of lease payments, the Company uses its incremental borrowing rate which represents an estimated rate of interest that the Company would have to pay to borrow equivalent funds on a collateralized basis at the lease commencement date. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the statement of operations. Goodwill Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill is not amortized but instead is tested annually for impairment at the reporting unit level, or more frequently when events or changes in circumstances indicate that fair value of the reporting unit has been reduced to less than its carrying value. The Company may choose to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a quantitative assessment. If a quantitative assessment is deemed necessary, the Company compares the fair value of the reporting unit with its carrying amount, including goodwill. An impairment loss will be recognized if the reporting unit’s carrying amount exceeds its fair value, to the extent that it does not exceed the total carrying amount of goodwill. No impairment existed as of December 31, 2022 or December 31, 2021 . Impairment of Long-Lived Assets The Company accounts for the impairment of long-lived assets, such as property and equipment, by reviewing these assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group to be tested for possible impairment, the Company first compares undiscounted future cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted-cash-flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. The Company recorded impairment of $ 0.5 million during the year ended December 31, 2022 . No impairment was recorded for the year ended December 31, 2021 . Fair Value of Financial Instruments The Company’s financial assets and liabilities are carried at fair value or at amounts that, because of their short-term nature, approximate current fair value, with the exception of its Convertible Notes, which are carried at amortized cost. The carrying value of the Company’s accounts receivable, accounts payable, and accrued expenses and other current liabilities are considered to be representative of their respective fair values because of their short-term nature (see Note 7 ). Embedded Derivative Related to Convertible Notes In December 2020, the Company issued Convertible Notes with an embedded derivative that was required to be bifurcated from the host contract and remeasured to fair value at each balance sheet date. Any resulting gain or loss related to the change in the fair value of the embedded derivative was recorded to other income, net in the consolidated statements of operations. As of December 31, 2022, the conversion option has expired and the Company no longer has an embedded derivative. Common Stock Warrant Liabilities The Company accounts for common stock warrants issued as freestanding instruments in accordance with applicable accounting guidance as either liabilities or as equity instruments depending on the specific terms of the warrant agreements. Warrants classified as liabilities are remeasured each period until settled or until classified as equity. Any resulting gain or loss related to the changes in the fair value of the warrant liabilities are recorded to gain (loss) on warrant liabilities in the consolidated statements of operations. Changes in the Company’s inputs and assumptions, such as the Company’s stock price and volatility of common stock, could result in material changes in the valuation in future periods. Repairs and Maintenance The Company incurs maintenance costs on its major equipment. Repair and maintenance costs are expensed as incurred. Research and Development Research and development expenses consist primarily of costs associated with performing research and development activities to develop new products. Research and development expenses also consist of personnel expenses, including salaries, bonuses, stock-based compensation expense, and benefits, and allocated overhead costs. Research and development expenses are expensed as incurred. Selling, General and Administrative Selling, general and administrative expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation expense, and benefits, for the Company's finance and accounting, legal, human resources, and other administrative teams. Additionally, these expenses include costs for communication, advertising, conferences, and professional fees of audit, legal, and recruiting services. Selling, general and administrative expenses are expensed as incurred. Advertising expense for the year ended December 31, 2021 was $ 0.6 million, and there were no advertising expenses for the year ended December 31, 2022 . Stock-Based Compensation Stock-based compensation related to stock options, restricted stock units (“RSUs”) and the 2020 Employee Stock Purchase Plan (“ESPP”) awards granted to the Company’s employees is measured at the grant date based on the fair value of the award. The fair value is recognized as expense over the requisite service period, which is generally the vesting period of the respective awards. Compensation related to service-based awards is recognized starting on the grant date on a straight-line basis over the vesting period, which is typically four years . For the ESPP, the requisite service period is generally the period of time from the offering date to the purchase date. In addition, the Company grants stock option awards that vest upon achievement of certain performance criteria ("Performance Awards"). The fair value is recognized as expense over the requisite service period when the Company has concluded that achieving the performance criteria is probable. The probability of achieving the performance criteria is assessed each reporting period. The Company accounts for the forfeitures in the period in which they occur. The fair value of RSUs is estimated based on the closing price of the Company's common stock on the date of the grant. The fair value of stock options, ESPP awards and Performance Awards is estimated using the Black-Scholes option-pricing model and is affected by the Company’s assumptions regarding a number of complex and subjective variables. These variables include, but are not limited to, the fair value of the common stock at the date of grant, the expected term of the awards, the expected stock price volatility over the term of the awards, risk-free interest rate, and dividend rate. The Company’s inputs and assumptions with respect to these variables are as follows: Fair Value of Common Stock — Prior to the IPO, the Company’s common stock was not publicly traded, therefore the Company estimated the fair value of its common stock. Following the initial public offering of the Company's common stock (the "IPO"), the fair value of the Company’s common stock for awards with service-based vesting is the closing price of its common stock on the date of grant or other relevant determination date. Expected Term —The expected term represents the period that the stock-based awards are expected to be outstanding. The Company determines the expected term using the simplified method. The simplified method deems the term to be the average of the time-to-vesting and the contractual life of the options. For stock options granted to non-employees, the expected term equals the remaining contractual term of the option from the vesting date. For the ESPP, the expected term is the period of time from the offering date to the purchase date. Expected Volatility —Given the limited period of time the Company’s stock has been traded in an active market, the expected volatility is estimated by taking the average historical volatility for industry peers, consisting of several public companies in the Company’s industry that are similar in size, stage, or financial leverage, over a period of time commensurate with the expected term of the awards. Risk-Free Interest Rate —The risk-free interest rate is calculated using the average of the published interest rates of U.S. Treasury zero-coupon issues with maturities that are commensurate with the expected term. Dividend Rate —The dividend yield assumption is zero , as the Company has no plans to pay dividends. Net Loss Per Share Basic net loss per share is computed by dividing the net loss by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing the net loss by the weighted average number of shares of common stock and potentially dilutive securities outstanding for the period. As the Company has reported net losses for all periods presented, all potentially dilutive securities are antidilutive and, accordingly, basic net loss per share equals diluted net loss per share. Income Taxes The Company accounts for income taxes under the asset-and-liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50 % likely of being realized. Changes in recognition or measurement are recognized in the period in which the change in judgment occurs. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. Comprehensive Loss The Company did no t have any other comprehensive income or loss for any of the periods presented, and therefore comprehensive loss was the same as the Company’s net loss. Emerging Growth Company Status The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). Under the JOBS Act, EGCs can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. Recent Accounting Pronouncements Adopted In February 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) , which supersedes FASB ASC Topic 840, Leases (Topic 840) , and provides principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The Company adopted the provisions of this guidance on January 1, 2022, using the effective date method. As a result of adopting ASC 842, the Company recognized right-of-use assets and lease liabilities of $ 2.2 million and $ 2.2 million, respectively, on January 1, 2022. The difference between the right-of-use assets and lease liabilities is attribut ed to the elimination of deferred rent and prepaid rent. There was no adjustment to the opening balance of accumulated deficit as a result of the adoption. The Company elected to use the package of practical expedients available in the new lease standard, allowing it not to reassess: (a) whether expired or existing contracts contain leases under the new definition of a lease; (b) lease classification for expired or existing leases; and (c) whether previously capitalized initial direct costs would qualify for capitalization under the new lease standard. In May 2021, the FASB issued ASU No. 2021-04 , Issuer's Accounting for Certain Modification or Exchanges of Freestanding Equity-Classified Written Call Options , which provides a principles-based framework to determine whether an issuer should recognize the modification or exchange as an adjustment to equity or an expense. The Company adopted this standard on January 1, 2022 , which did not have a material impact on the consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses , which requires the measurement of expected credit losses for financial instruments carried at amortized cost, such as accounts receivable, held at the reporting date based on historical experience, current conditions and reasonable forecasts. The main objective of this standard is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financing Instruments–Credit Losses , which included an amendment of the effective date. The standard is effective for the Company for annual reporting periods beginning after December 15, 20 22. The Company does not expect the adoption of this standard to have a significant impact on its consolidated financial statements. In August 2020, the FASB issued ASU No. 2020-06 , Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40)-Accounting for Convertible Instruments and Contracts in an Entity's Own Equity , which simplifies the accounting for convertible instruments, amends the guidance on derivative scope exceptions for contracts in an entity's own equity, and modifies the guidance on diluted earnings per share calculations as a result of these changes. The standard is effective for the Company for annual reporting periods beginning after December 15, 2023. The Company is currently evaluating the impact the adoption of this standard may have on its consolidated financial statements. |

Variable Interest Entity | Note 3. Variable Interest Entity In June 2015, the Company, through a wholly-owned subsidiary, entered into a series of agreements with Avero. The subsidiary entity entered into a purchase agreement to acquire certain assets from Mattison used in the operations of Avero. The purchase agreement was accounted for under the acquisition method in accordance with the provisions of ASC Topic 805, Business Combinations . The subsidiary entity also entered into a nominee agreement which provided it with the right, but not the obligation, to purchase, or to designate a person(s) to purchase, the stock of Avero at any time for a nominal amount. In December 2021, the Company entered into an asset purchase agreement with Northwest Pathology to sell certain assets and liabilities of Avero for $ 10.9 million. The Company no longer has any ownership interest in Avero and therefore does not consolidate Avero beginning at December 31, 2021. Prior to the date of sale, Avero's income statement activity is included in discontinued operations in the consolidated statements of operations. In June 2015, t he Company's subsidiary entity entered into a management services arrangement that authorized the Company to perform the management services in the manner that it deemed reasonably appropriate to meet the day-to-day business needs of Avero. The management services included funding ongoing operational needs, directing activities related to contract negotiation, billing, human resources, and legal and administrative matters and processes, among others. In exchange for the management services provided, the Company's subsidiary entity was entitled to receive an annual management fee equal to the amount of the net operating income of Avero. The agreement had a 10 -year term, but was terminated at the time of the sale of Avero. Through the management services arrangement with Avero, the Company had (1) the power to direct the activities of Avero that most significantly impact its economic performance, and (2) the obligation to absorb losses of Avero or the right to receive benefits from Avero that could potentially be significant to Avero. Based on these determinations, the Company determined that Avero was a variable interest entity ("VIE") and that the Company was the primary beneficiary. The Company did not own any equity interest in Avero; however, as these agreements provide the Company the controlling financial interest in Avero, the Company consolidated Avero’s balances and activities within its consolidated financial statements. |

Strategic Transformation | Note 4. Strategic Transformation In June 2021, the Company announced its Strategic Transformation to reallocate resources to research and development to better position the business for future growth. The plan included the closure of the Company's genetics laboratory in Ann Arbor, Michigan and the divestiture of Avero. This plan represents a strategic business shift having a major effect on the Company's operations and financial results. The Company classified the results of its Laboratory Operations as discontinued operations in its consolidated statements of operations and consolidated statements of cash flows for all periods presented. Additionally, the remaining assets have been reported as assets held for sale in the Company’s consolidated balance sheets as of December 31, 2022 and December 31, 2021. The Company recognized a loss of $ 19.3 million fo r the year ended December 31, 2021 for contract terminations, severance, inventory and fixed asset write-downs in discontinued operations related to the genetics laboratory shutdown. The Company received revenue in connection with the reimbursement for tests that were run prior to the closure of its Laboratory Operations through September 2022. In December 2021, the Company entered into an asset purchase agreement to sell certain assets and liabilities of Avero for gross proceeds of $ 10.9 million. The Company recognized a loss o f $ 6.0 million in discontinued operations , calculated as proceeds less net assets of $ 15.1 million and transaction costs of $ 1.8 million, for the year ended December 31, 2021. The following table presents the combined results of discontinued operations of the Laboratory Operations (in thousands): Year Ended December 31, 2022 2021 Revenues (1) $ 11,848 $ 59,362 Cost of sales — 63,741 Gross profit (loss) 11,848 ( 4,379 ) Operating expenses: Research and development — 1,590 Selling and marketing — 38,753 General and administrative 1,175 18,247 Total operating expenses 1,175 58,590 Other expense, net — ( 5,922 ) Net income (loss) from discontinued operations $ 10,673 $ ( 68,891 ) (1) Refer to Note 10 for further discussion regarding the partial reversal of a previously-established accrual related to a third-party claim of recoupment during the year ended December 31, 2022. The following table presents the carrying amounts of the remaining assets held for sale related to the Laboratory Operations as of December 31, 2022 and December 31, 2021 (in thousands): December 31, December 31, Current assets of disposal group held for sale Property and equipment, net 2,603 2,493 Total current assets of disposal group held for sale (2) $ 2,603 $ 2,493 (2 ) The Company is actively looking to sell the remaining assets of the Laboratory Operations and has classified them as held for sale and current in the consolidated balance sheets at December 31, 2022 and December 31, 2021 . Investment in Enumera Molecular, Inc. In May 2022, the Company completed the divesture of its single-molecule detection platform. Under the terms of the agreements, the Company contributed intellectual property and fixed assets related to the single-molecule detection platform to a newly-formed entity, Enumera Molecular, Inc. ("Enumera"), which intends to develop and commercialize the platform. As of the transaction date, the Company received 25 % minority ownership, on a fully-diluted basis, of 6,000,000 Series A-1 preferred shares with an estimated value of $ 6.0 million in exchange for the assets. The Company performed a VIE analysis and concluded Enumera does not meet the definition of a VIE. The Company also evaluated the characteristics of the investment and determined that the preferred stock is not in-substance common stock that would require equity method accounting. The Company concluded the appropriate accounting treatment for the investment in Enumera to be that of an equity security with no readily-determinable fair value and has recorded the investment at cost, less impairment, adjusted for subsequent observable price changes. The investment is included in other assets in the Company’s consolidated balance sheets as of December 31, 2022 . The Company recognized a gain of $ 5.7 million on the investment during the year ended December 31, 2022 included in other income, net on the consolidated statements of operations and there was no impairment recorded. Northwest License Agreement In November 2022, the Company entered into a license agreement with Northwest Pathology, doing business as Avero Diagnostics (“Northwest”), pursuant to which the Company licenses its Preecludia rule-out test for preeclampsia to Northwest for commercial development (the “Northwest License Agreement”). Under the terms of the Northwest License Agreement, Northwest receives rights to assets and intellectual property related to the Preecludia test and the Company will receive commercial milestone payments and royalties on net sales. |

Revenue from Contract with Customer [Abstract] | |
Revenues | Note 5. Revenues The Company’s revenues are generated primarily through collaboration agreements. Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration that the Company expects to be entitled to receive in exchange for these services. The Company analyzes the nature of these performance obligations in the context of individual agreements in order to assess the distinct performance obligations. The Company applies the following five steps to recognize revenue: (1) identify the contract with the customer, (2) identify the performance obligations, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations and (5) recognize revenues when the performance obligations are satisfied. The Company evaluates all promised goods and services within a customer contract and determines which of such goods and services are separate performance obligations. This evaluation includes an assessment of whether the good or service is capable of being distinct and whether the good or service is separable from other promises in the contract. The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring goods and services to the customer. A contract may contain variable consideration, including potential payments for both milestone and research and development services. For certain potential milestone payments, the Company estimates the amount of variable consideration by using the most likely amount method. Each reporting period the Company re-evaluates the probability of achievement of such variable consideration and any related constraints. The Company will include variable consideration, without constraint, in the transaction price to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price among the performance obligations on a relative standalone selling price basis unless the transaction price is variable and meets the criteria to be allocated entirely to a performance obligation or to a distinct good or service that forms part of a single performance obligation. Revenues historically were derived from contracts with healthcare insurers, government payors, laboratory partners and patients in connection with sales of prenatal genetic, anatomic or molecular pathology tests. The Company entered into contracts with healthcare insurers related to tests provided to patients who had health insurance coverage. Insurance carriers are considered third-party payors on behalf of the patients, and the patients who receive genetic, anatomic or molecular pathology test products are considered the customers. Tests were billed to insurance carriers, patients, or a combination of insurance carriers and patients. The Company also sold tests to laboratory partners, which are considered customers. The Company evaluated its contracts with healthcare insurers, government payors, laboratory partners and patients and identified a single performance obligation, the delivery of a test result. The Company satisfied its performance obligation at a point in time upon the delivery of the test result, at which point the Company can bill for its products. The amount of revenue recognized reflects the transaction price and considers the effects of variable consideration, which is discussed below. Once the Company satisfied its performance obligations upon delivery of a test result and billed for the product, the timing of the collection of payments may vary based on the payment practices of the third-party payor. The Company billed patients directly for co-pays and deductibles that they are responsible for and also billed patients directly in cases where the customer did not have insurance. All of the historical test revenue is part of the Company's Laboratory Operations and has been included in discontinued operations in the consolidated statements of operations. The Company had established an accrual for refunds of payments previously made by healthcare insurers based on historical experience and executed settlement agreements with healthcare insurers. Any refunds are accounted for as reductions in revenues in the statement of operations as an element of variable consideration. The transaction price was an estimate and could be fixed or variable. Variable consideration includes reimbursement from healthcare insurers, government payors, and patients and is adjusted for estimates of disallowed cases, discounts, and refunds using the expected value approach. Tests billed to healthcare insurers and directly to patients can take up to nine months to collect and the Company may be paid less than the full amount billed or not paid at all. For insurance carriers and government payors, management utilizes the expected value method using a portfolio of relevant historical data for payors with similar reimbursement characteristics. The portfolio estimate is developed using historical reimbursement data from payors and patients, as well as known current reimbursement trends not reflected in the historical data. Such variable consideration is included in the transaction price only to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainties with respect to the amount are resolved. The Company monitors these estimates at each reporting period based on actual cash collections and the status of settlement agreements with third-party payors, in order to assess whether a revision to the estimate is required. Both the initial estimate and any subsequent revision to the estimate contain uncertainty and require the use of judgment in the estimation of the transaction price and application of the constraint for variable consideration. If actual results in the future vary from the Company’s estimates, the Company will adjust these estimates, which would affect revenue and earnings in the period such variances become known. The consideration expected from laboratory partners is generally a fixed amount. The Company periodically updated its estimate of the variable consideration recognized for previously-delivered performance obligations. These updates resulted in an additional $ 2.0 million and $ 6.6 million of revenue reported for the years ended December 31, 2022 and December 31, 2021, respectively. These amounts included (i) adjustments for actual collections versus estimated variable consideration as of the beginning of the reporting period and (ii) cash collections and the related recognition of revenue in the current period for tests delivered in prior periods due to the release of the constraint on variable consideration, offset by (iii) reductions in revenue for the accrual for reimbursement claims and settlements described in Note 10. Disaggregation of Revenues As a result of the classification of Laboratory Operations to discontinued operations, the Company is only showing disaggregation for prior year. The Company's current revenue is related to license and collaboration agreements. The following tables show revenues disaggregated by payor type and revenue classification (in thousands): Year Ended Commercial third-party payors $ 42,100 Government health benefit programs (1) 14,085 Patient/laboratory distribution partners 4,424 Total revenues $ 60,609 (1) The revenue amounts include accruals for reimbursement claims and settlements included in the estimates of variable consideration recorded during the year ended December 31, 2021 . Revenues recognized reflect the effects of variable consideration, and include adjustments for estimates of disallowed cases, discounts, and refunds. The variable consideration includes reductions in revenues for the accrual for reimbursement claims and settlements.

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Note 7. Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The authoritative guidance establishes a three-level valuation hierarchy that prioritizes the inputs to valuation techniques used to measure fair value based upon whether such inputs are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions made by the reporting entity. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. The three-level hierarchy for the inputs to valuation techniques is summarized as follows: Level 1 - Quoted prices in active markets for identical assets and liabilities that the Company has the ability to access. Level 2 - Observable market-based inputs or unobservable inputs that are corroborated by market data, such as quoted prices, interest rates, and yield curves. Level 3 - Inputs that are unobservable data points that are not corroborated by market data. There were no significant transfers between these fair value measurement classifications during the years ended December 31, 2022 and 2021. Fair Value of Financial Instruments The Company’s Level 3 liabilities consist of the embedded derivative liability associated with the Company’s Convertible Notes (see Note 8) and the warrant liabilities resulting from the November 2022 and August 2021 issuance of warrants (see Note 11). The Convertible Notes conversion feature was bifurcated and recorded as an embedded derivative liability with a corresponding discount at the date of issuance that is netted against the principal amount of the Convertible Notes. The Company utilizes a Monte Carlo simulation method to determine the fair value of the conversion feature, which utilizes inputs including the common stock price, volatility of common stock, the risk-free interest rate and the probability of conversion to common shares at the conversion rate in the event of a major transaction (e.g. a change in control). Due to the use of significant unobservable inputs, the overall fair value measurement of the conversion feature is classified as Lev el 3. As of December 31, 2021, the fair value of the embedded derivative liability was zero . As of December 31, 2022, the conversion option has expired and there is no longer an embedded derivative. The Company uses the Black-Scholes Model to value the Level 3 warrant liabilities at inception and on subsequent valuation dates. This model incorporates transaction details such as the Company’s stock price, contractual terms, maturity, risk free rates, and volatility. The significant unobservable input for the Level 3 warrant liabilities include volatility. Given the limited period of time the Company’s stock has been traded in an active market, the expected volatility is estimated by taking the average historical price volatility for industry peers, consisting of several public companies in the Company’s industry that are similar in size, stage, or financial leverage, over a period of time commensurate to the expected term of the warrants. At December 31, 2022 and 2021, the fair value of the warrant liabilities were estimated using the Black-Scholes Model with the following inputs and assumptions: December 31, December 31, Risk-free interest rate 4.0 % 1.3 % Expected volatility 106.2 % - 107.1 % 91.9 % Stock price $ 3.30 $ 52.25 Expected life (years) 3.6 - 5.4 4.6 The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value (in thousands): Level 1 Level 2 Level 3 December 31, 2022 Money market funds (1) $ 5 $ — $ — Warrant Liabilities $ — $ — $ 3,538 December 31, 2021 Money market funds (1) $ 85,866 $ — $ — Warrant Liabilities $ — $ — $ 18,731 (1) Included in cash and cash equivalents in the accompanying consolidated balance sheets. The carrying value of the Company’s Convertible Notes does not approximate its fair value because the carrying value of the Convertible Notes reflects the balance of unamortized discount related to the derivative liability associated with the value of the conversion feature assessed at inception. The carrying value of the Company’s Convertible Notes, net of discount, was $ 127.8 million and $ 126.4 million at December 31, 2022 and 2021, respectively. Based on unadjusted quoted prices in active market obtained from third-party pricing services, the Company determined the fair value of the Convertible Notes was $ 71.8 million and $ 86.6 million as of December 31, 2022 and 2021 , respectively. |

Convertible Notes | Note 8. Convertible Notes In December 2020, the Company issued a total of $ 168.5 million principal amount of Convertible Notes in a private offering of the Convertible Notes pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"). The Convertible Notes were issued pursuant to, and are governed by, an indenture, dated as of December 7, 2020 , by and between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee ("Indenture"). The Convertible Notes are due on December 1, 2025 , unless earlier repurchased, redeemed or converted, and accrue interest at a rate per annum equal to 7.25 % payable semi-annually in arrears on June 1 and December 1 of each year, with the initial payment on June 1, 2021 . The outstanding principal amount of Convertible Notes wa s $ 132.7 million at both December 31, 2022 and December 31, 2021. During the years ended December 31, 2022 and 2021, the Company recognized interest expense on the Convertible Notes of $ 9.6 million and $ 11.7 million, respectively. The Convertible Notes are the Company's senior, unsecured obligations and are (i) equal in right of payment with the Company's existing and future senior, unsecured indebtedness; (ii) senior in right of payment to the Company's existing and future indebtedness that is expressly subordinated to the Convertible Notes; (iii) effectively subordinated to the Company's existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness; and (iv) structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company's subsidiaries. At any time, noteholders may convert their Convertible Notes at their option into shares of the Company’s common stock, together, if applicable, with cash in lieu of any fractional share, at the then-applicable conversion rate. The initial conversion rate is 11.1204 shares of common stock per $1,000 principal amount of Convertible Notes, which represents an initial conversion price of approximately $ 89.92 per share of common stock. Noteholders that converted their Convertible Notes before December 1, 2022 were, in certain circumstances, entitled to an additional cash payment representing the present value of any remaining interest payments on the Convertible Notes through December 1, 2022. The conversion rate and conversion price are subject to customary adjustments upon the occurrence of certain dilutive events. In addition, if certain corporate events that constitute a “Make-Whole Fundamental Change” (as defined in the Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time. The Convertible Notes are redeemable, in whole and not in part, at the Company’s option at any time on or after December 1, 2023 , at a cash redemption price equal to the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of the Company’s common stock exceeds 130 % of the conversion price on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (ii) the trading day immediately before the date the Company sends such notice. In addition, calling the Convertible Notes will constitute a Make-Whole Fundamental Change, which will result in an increase to the conversion rate in certain circumstances for a specified period of time. The Convertible Notes have customary provisions relating to the occurrence of “Events of Default” (as defined in the Indenture), which include the following: (i) certain payment defaults on the Convertible Notes (which, in the case of a default in the payment of interest on the Convertible Notes, will be subject to a 30-day cure period); (ii) the Company’s failure to send certain notices under the Indenture within specified periods of time; (iii) the Company’s failure to comply with certain covenants in the Indenture relating to the Company’s ability to consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its subsidiaries, taken as a whole, to another person; (iv) a default by the Company in its other obligations or agreements under the Indenture or the Convertible Notes if such default is not cured or waived within 60 days after notice is given in accordance with the Indenture; (v) certain defaults by the Company or any of its subsidiaries with respect to indebtedness for borrowed money of at least $ 7.5 million; (vi) the rendering of certain judgments against the Company or any of its subsidiaries for the payment of at least $7.5 million, where such judgments are not discharged or stayed within 60 days after the date on which the right to appeal has expired or on which all rights to appeal have been extinguished ; and (vii) certain events of bankruptcy, insolvency and reorganization involving the Company or any of the Company’s significant subsidiaries . As of December 31, 2022 and December 31, 2021, the Company was in compliance with all such covenants. The Convertible Notes had a conversion option which was required to be bifurcated upon issuance and periodically remeasured to fair value separately as an embedded derivative. The conversion option included additional interest payments payable to the noteholders if converted prior to December 1, 2022 (the "Early Voluntary Conversion Option"). The conversion feature was bifurcated and recorded separately as an embedded derivative as (1) the conversion feature was not clearly and closely related to the debt instrument and was not considered to be indexed to the Company’s equity, (2) the conversion feature standing alone meets the definition of a derivative, and (3) the Convertible Notes are not remeasured at fair value each reporting period with changes in fair value recorded in the consolidated statement of operations. The fair value of the embedded derivative was zero as of December 31, 2021. As of December 31, 2022, the conversion option has expired and there is no longer an embedded derivative. The prior year change in fair value of the derivative liability of $ 18.4 million is included in other income (expense), net in the consolidated statement of operations for the year ended December 31, 2021. As of December 31, 2022 and 2021, the unamortized debt discount was $ 4.9 million and $ 6.3 million, respectively. The Company amortizes the debt discount using the effective interest method over the term of the Convertible Notes, resulting in an effective interest rate of approximately 8.7 %. For the years ended December 31, 2022 and 2021 the amortization of the Convertible Notes debt discount was $ 1.4 million and $ 1.6 million, respectively, and is included in interest expense, net in the consolidated statements of operations. In October 2021, holders of Convertible Notes exchanged an aggregate of $ 20.2 million principal amount for 340,554 shares of the Company's common stock. As the Convertible Notes were exchanged for an amount over the fair value of shares issuable under the original conversion terms, the Company recorded an inducement loss of $ 9.8 million, included in other income (expense) in the consolidated statements of operations. In addition, the Company issued an aggregate of 17,112 shares of common stock to certain investors in consideration for a waiver of certain contractual lock-up provisions to which the Company agreed to in connection with prior offerings of its securities. The Company recorded an inducement loss of $ 1.4 million in other income (expense), net, in the consolidated statements of operations, related to these shares. In addition to the transaction discussed above, holders of Convertible Notes exchanged an aggregate of $ 15.6 million principal amount for 173,477 shares of the Company's common stock during the year ended December 31, 2021 . The Convertible Notes were converted under the Early Voluntary Conversion Option and the Company recognized a $ 0.9 million extinguishment loss, which is included in other income, net in the consolidated statements of operations. |

Athyrium also holds $ 103.5 million aggregate principal amount of Convertible Notes as of both December 31, 2022 and 2021 (see Note 8). During the year ended December 31, 2021, Athyrium entered into an agreement with the Company to waive its interest due of $ 3.6 million through June 1, 2021 and received 50,724 shares of common stock. As of both December 31, 2022 and 2021 , the accrued interest expense related to the Convertible Notes was $ 0.6 million. In November 2022, the Company entered into a securities purchase agreement with affiliates of Athyrium relating to the offering and sale of an aggregate of 500,250 shares of common stock and accompanying warrants to purchase 500,250 shares of common stock, at a combined purchase price of $ 7.50 per share and accompanying warrant in a registered direct offering. The warrants have an exercise price of $ 8.22 per share and will become exercisable commencing six months following the date of issuance and will expire five years following the initial exercise date. The Company received approximately $ 3.8 million in gross proceeds from the offering as an in-kind payment. The in-kind payment was in the form of a waiver of the Company’s cash interest payment obligation of approximately $ 3.8 million due on certain of the Company’s 7.25 % Convertible Senior Notes due 2025 held by affiliates of Athyrium for the payment date occurring on December 1, 2022. Additionally, the Company agreed with Athyrium to amend outstanding warrants previously issued in 2021 to purchase up to 323,886 shares of common stock with an exercise price of $ 71.00 per share. The warrants have an amended exercise price of $ 8.22 per share, will become exercisable on May 9, 2023 and will expire five years following the initial exercise date. As of December 31, 2022 , Athyrium held 1,694,484 shares, or 19.0 % of the Company's common stock outstanding and warrants to purchase up to 824,136 shares of common stock at an exercise price of $ 8.22 . In November 2022, the Company entered into a securities purchase agreement with an institutional investor relating to the offering and sale of an aggregate of 800,000 shares of common stock and accompanying warrants to purchase 800,000 shares of common stock, at a combined purchase price of $ 7.50 per share and accompanying warrant in a registered direct offering (see Note 11 ). Following this transaction, the institutional investor became a related party due to greater than 5 % ownership. On January 12, 2023, the Company issued warrants to purchase 90,000 shares of common stock to the institutional investor in exchange for the investor’s agreement to waive the lockup provisions contained in the securities purchase agreement from the November 2022 Offering (as defined below) .

Commitments and Contingencies | Note 10. Commitments and Contingencies Operating Leases The Company has entered into various non-cancelable operating lease agreements, primarily for office space, laboratory space, and equipment. On January 1, 2022, the Company adopted ASC Topic 842, Leases. Results for reporting periods beginning after January 1, 2022 are presented under ASC 842, while prior period amounts are not adjusted and continue to be reported in accordance with historic accounting guidance. The right-of-use assets w ere $ 1.5 million as of December 31, 2022 and current and long-term lease liabilities were $ 0.9 million and $ 0.6 million, respectively, as of December 31, 2022, and are recorded in accrued expenses and other current liabilities and other long-term liabilities on the consolidated balance sheet. Operating lease costs were $ 1.5 million for the year ended December 31, 2022 and cash paid for operating leases was $ 1.6 million. The weighted-average discount rate used was 7.8 % and the weighted-average remaining lease term for all operating leases was 2.3 years. Rent expense included in continuing operations for operating leases was $ 5.1 million for the year ended December 31, 2021. As of December 31, 2022, future lease payments under the non-cancelable operating leases were as follows (in thousands): Year ending December 31, Minimum 2023 $ 965 2024 235 2025 209 2026 215 2027 and thereafter 18 Total minimum lease payments 1,642 Less: interest ( 148 ) Present value of lease liabilities $ 1,494 As of December 31, 2021, net minimum payments under the non-cancelable operating leases were as follows (in thousands): Year ending December 31, Minimum 2022 $ 2,141 2023 1,086 2024 237 2025 208 2026 and thereafter 251 Total future minimum lease payments $ 3,923 Contingencies The Company, in the ordinary course of its business, can be involved in lawsuits, threats of litigation, and audit and investigative demands from third parties. While management is unable to predict the exact outcome of such matters, it is management’s current belief that any potential liabilities of Biora resulting from these contingencies, individually or in the aggregate, could have a material impact on the Company’s financial position and results of operations. The regulations governing government reimbursement programs (e.g., Medicaid, Tricare, and Medicare) and commercial payor reimbursement programs are complex and may be subject to interpretation. As a former provider of services to patients covered under government and commercial payor programs, post payment review audits, and other forms of reviews and investigations are routine. The Company believes it complied in all material respects with the statutes, regulations, and other requirements applicable to its former laboratory operations. Federal Investigations In April 2018, the Company received a civil investigative demand from an Assistant U.S. Attorney (“AUSA”) for the Southern District of New York and a Health Insurance Portability and Accountability Act subpoena issued by an AUSA for the Southern District of California (“SDCA”) around legacy commercial practices. In May 2018, the Company received a subpoena from the State of New York Medicaid Fraud Control Unit. On July 21, 2020, July 23, 2020 and October 1, 2020, the Company entered into agreements ("the Agreements") with certain governmental agencies and the 45 states participating in the settlement (“State AGs”) to resolve, with respect to such agencies and State AGs, all of such agencies’ and State AGs’ outstanding civil, and, where applicable, federal criminal investigations described above. The Company paid approximately $ 5.0 million as required by the Agreements during the year ended December 31, 2021. As of December 31, 2021 , the Company’s accrual consisted of $ 6.9 million in accrued expenses and other current liabilities and $ 0.2 million in other long-term liabilities. In November 2022, the Company entered into an agreement to extend the deadline for the Company’s payment due on December 31, 2022 to July 15, 2023 and the Company did not make any payments during the year ended December 31, 2022. The remaini ng amounts payable to the government will be subject to interest at a rate of 1.25 % per annum, and any or all amounts may be paid earlier at the option of the Company. As of December 31, 2022, the Company’s accrual consist s of $ 7.1 million in accrued expens es and other current liabilities. Furthermore, the Company has agreed that, if during calendar years 2020 through 2023, and so long as amounts payable to the government remain unpaid, the Company receives any civil settlement, damages awards, or tax refunds, to the extent that the amounts exceed $ 5.0 million in a calendar year, it will pay 26 % of the amount received in such civil settlement, damages award, or tax refunds as an accelerated payment of the scheduled amounts set forth above, up to a maximum total acceleration of $ 4.1 million. The Company did no t receive any tax refunds during the years ended December 31, 2022 and 2021. Non-Prosecution Agreement Effective July 21, 2020, the Company entered into the Non-Prosecution Agreement, pursuant to which the Company agreed with the DOJ to (i) pay the restitution provided for under the SDCA Civil Settlement Agreement, (ii) not commit any felonies, (iii) continue to implement a compliance and ethics program designed to prevent and detect violations of applicable fraud and kickback laws throughout its operations and (iv) fulfill certain other disclosure, reporting and cooperation obligations. The DOJ agreed that it will not prosecute the Company for any conduct described in the Non-Prosecution Agreement provided that the Company performs its obligations under the Non-Prosecution Agreement during the period from July 21, 2020 through July 21, 2021. The Non-Prosecution Agreement expired on July 21, 2021. Corporate Integrity Agreement In connection with the resolution of the investigated matters, and in exchange for the Office of Inspector General of the Department of Health and Human Services ("OIG") agreement not to exercise its authority to permissively exclude the Company from participating in federal healthcare programs, effective July 21, 2020, the Company entered into a five-year Corporate Integrity Agreement with the OIG. The Corporate Integrity Agreement requires, among other matters, that the Company maintain a Compliance Officer, a Compliance Committee, board review and oversight of certain federal healthcare compliance matters, compliance programs, and disclosure programs; provide management certifications and compliance training and education; engage an independent review organization to conduct claims and arrangements reviews; and implement a risk assessment and internal review process. In view of the Company’s Strategic Transformation, including cessation of its Laboratory Operations and related billing for services, effective March 7, 2023 the OIG agreed to suspend the Company’s obligations under the Corporate Integrity Agreement. Colorado Recoupment On July 21, 2021, the Company received a letter from the Colorado Department of Health Care Policy and Financing (the "Department"), informing the Company that, as a result of a post-payment review of Medicaid claims from October 2014 to June 2018, the Department is seeking recoupment for historical payments in an aggregate amount of approximately $ 5.7 million. In December 2021, the Company received additional correspondence informing them that the Department is seeking recoupment for an additional $ 3.3 million of historical payments from 2018. The historical payments for which the Department is seeking recoupment primarily relate to the Company's Preparent expanded carrier screening tests primarily on the basis that such tests were not medically necessary. The Company disputed these claims of recoupment with the Department and filed administrative complaints with the State of Colorado Office of Administrative Courts. During the year ended December 31, 2022 , the Company concluded a settlement agreement resolution of the matter that included a dismissal of the complaints and a full release of all the claims, except for approximately $ 11,000 in claims, which the Company refunded. California Subpoena On July 19, 2021, the Company received a subpoena from the California Attorney General’s Office, Division of Public Rights (the "OAG"), requesting documents and information related to the Company's former genetic testing practices, the Company's former non-invasive prenatal tests ("NIPT"), particularly those with a nexus to California patients. The subpoena is captioned “In the Matter of the Investigation of: Prenatal Genetic Testing Companies.” The OAG has alleged that it has claims under California’s false advertising and unfair business practices laws based on representations about patient billing made in the historical marketing of the Company’s legacy genetic testing business. While the Company believes that its sales and marketing representations were appropriate, the Company is discussing a potential resolution with OAG, and producing additional materials in connection with those discussions, to determine if the matter can be concluded in the best interests of the Company. The Company is unable to predict the ultimate outcome of this action. Payor Settlement Agreements On September 30, 2019 , the Company entered into a settlement agreement with United HealthCare Services, Inc. and UnitedHealthcare Insurance Company in which the Company agreed to pay an aggregate amount of $ 30.0 million. In November 2019 , the Company and Aetna entered into a settlement agreement for $ 15.0 million. As of December 31, 2021 both settlements were fully paid. Payor Dispute On November 16, 2020, the Company received a letter from Anthem, Inc. ("Anthem") informing the Company that Anthem is seeking recoupment for historical payments made by Anthem in an aggregate amount of approximately $ 27.4 million. The historical payments for which Anthem is seeking recoupment are claimed to relate primarily to discontinued legacy billing practices for the Company’s former NIPT and microdeletion tests and secondarily to the implementation of the new Current Procedure Terminology code for reimbursement for the Company’s former Preparent expanded carrier screening tests. The Company has historically negotiated and settled similar claims with third-party payors. Although the Company’s practice in resolving disputes with other similar large commercial payors has generally led to agreed settlement amounts substantially less than the originally claimed amount, there can be no assurance that the Company will be successful in a similar settlement amount in any ongoing or future dispute. Historical settlement amounts and payment time periods may not be indicative of the final settlement terms with Anthem, if any. Management disputes this claim of recoupment with Anthem in full, with offsets for amounts owed by Anthem to the Company. Management had previously established an accrual for the estimated probable loss for this matter. During the year ended December 31, 2022, the Company reversed this accrual for a portion of the matter in view of applicable statute of limitations and has reflected this change in revenue within discontinued operations. Payor Recoveries As noted above, the regulations governing government reimbursement programs (e.g., Medicaid, Tricare, and Medicare) and commercial payor reimbursement programs are complex and may be subject to interpretation. As a former provider of services to patients covered under government reimbursement and commercial payor programs, the Company is routinely subject to post-payment review audits and other forms of reviews and investigations. For example, the Company is currently in the process of reviewing several managed Medicaid payor recoupment requests aggregating to $ 1.1 million. If a third-party payor successfully challenges that a payment to the Company for prior testing was in breach of contract or otherwise contrary to policy or law, they may recoup such payment. The Company may also decide to negotiate and settle with a third-party payor in order to resolve an allegation of overpayment. In the ordinary course of business, the Company addresses and evaluates a number of such claims from payors. In the past, the Company has negotiated and settled these types of claims with third-party payors. The Company may be required to resolve further disputes in the future. While management is unable to predict the exact outcome of any such claims, it is management’s current belief that any potential liabilities resulting from these contingencies, individually or in the aggregate, could have a material impact on the Company’s financial position and results of operations. Texas OIG Inquiry On October 16, 2019, the Company received an inquiry from the Texas Health & Human Services Commission Office of Inspector General (“TX OIG”) alleging that the Company did not hold the required CLIA Laboratory Certificate of Accreditation to perform, bill for, or be reimbursed by the Texas Medicaid Program for certain tests performed by us from January 1, 2015 through December 31, 2018. The Company submitted a written response to the inquiry on October 23, 2019. In October 2021, the Company received a letter from the TX OIG asking the Company to renew its engagement on the matter. During the year ended December 31, 2022, the Company fully resolved and settled the matter for an immaterial payment by the Company in exchange for a release of all claims. Ravgen Lawsuit On December 22, 2020, Ravgen, Inc. ("Ravgen") filed suit in the District of Delaware (D. Del. Civil Action No. 1:20-cv-1734) two Ravgen patents based on the Company's former NIPT testing business. The complaint seeks monetary damages and injunctive relief. The Company responded to the complaint on March 23, 2021. Management believes the claims in Ravgen’s complaint are without merit, and the Company is vigorously defending against them. On March 1, 2022 the court ordered a stay of the litigation pending resolution of patent validity challenges made against the two patents in inter partes review proceedings currently pending before the Patent Trial and Appeal Board of the United States Patent and Trademark Office. On February 13, 2023 the court ordered the stay lifted. Given the uncertainty of litigation, the early stages of the Ravgen litigation, and the legal standards that must be met for, among other things, success on the merits, the Company is unable to predict the ultimate outcome of these actions, and therefore cannot estimate the reasonably possible loss or range of loss, if any, that may result from this action. IPO Litigation On June 23, 2020, the Company closed its IPO. Lawsuits were filed on August 28, 2020 and September 11, 2020 against the Company, certain of its executive officers and directors, and the underwriters of the IPO. On December 3, 2020, the U.S. District Court for the Southern District of California consolidated the two actions, appointed Lin Shen, Lingjun Lin and Fusheng Lin to serve as Lead Plaintiffs, and approved Glancy Prongay & Murray LLP to be Lead Plaintiffs’ Counsel. Lead Plaintiffs filed their first amended complaint on February 4, 2021. Together with the underwriters of the IPO, the Company moved to dismiss the first amended complaint. On September 1, 2021, the court granted the Company's motion to dismiss, dismissing Lead Plaintiffs’ claims without prejudice. On September 22, 2021, Lead Plaintiffs filed their second amended complaint. Together with the underwriters of the IPO, the Company moved to dismiss the second amended complaint on November 15, 2021. On January 13, 2023, the court again granted our motion to dismiss, dismissing Lead Plaintiffs’ claims for failure to state a claim without prejudice. On February 3, 2023, Lead Plaintiffs filed their third amended complaint, adding information allegedly produced to Plaintiffs in response to freedom of information requests. The third amended complaint alleges that the Company’s registration statement and related prospectus for the IPO contained false and misleading statements and omissions in violation of the Securities Act by failing to disclose that (i) the Company had overbilled government payors for Preparent tests beginning in 2019 and ending in or before early 2020; (ii) there was a high probability that the Company had received, and would have to refund, a material amount of overpayments from government payors for Preparent tests; (iii) in February 2020 the Company ended a supposedly improper marketing practice on which the competitiveness of the Company's business depended; and (iv) the Company was suffering from material negative trends with respect to testing volumes, average selling prices for its tests, and revenues. Lead Plaintiffs seek certification as a class, unspecified compensatory damages, interest, costs and expenses including attorneys’ fees, and unspecified extraordinary, equitable, and/or injunctive relief. The Company intends to continue to vigorously defend against these claims. Subject to a reservation of rights, the Company is advancing expenses subject to indemnification to the underwriters of the IPO. On June 4, 2021, a purported shareholder filed a lawsuit in the U.S. District Court for the SDCA, claiming to sue derivatively on behalf of the Company. The complaint names certain of the Company’s officers and directors as defendants, and names the Company as a nominal defendant. Premised largely on the same allegations as the above-described securities lawsuit, it alleges that the individual defendants breached their fiduciary duties to the Company, wasted corporate assets, and caused the Company to issue a misleading proxy statement in violation of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The complaint seeks the award of unspecified damages to the Company, equitable and injunctive remedies, and an order directing the Company to reform and improve its internal controls and board oversight. It also seeks the costs and disbursements associated with bringing suit, including attorneys’, consultants’, and experts’ fees. The case is stayed pending the outcome of the motion to dismiss in the above-described securities lawsuit. The Company intends to vigorously defend against these claims. On August 17, 2021, the Company received a letter purportedly on behalf of a stockholder of the Company demanding that the Company's board of directors investigate and take action against certain of the Company’s current and former officers and directors to recover damages for alleged breaches of fiduciary duties and related claims arising out of the IPO litigation discussed above. This matter is pending the outcome of the companion securities litigation. Given the uncertainty of litigation, the preliminary stages of the litigation and other matters described above, and the legal standards that must be met for, among other things, success on the merits, the Company is unable to predict the ultimate outcome of these actions, and therefore cannot estimate the reasonably possible loss or range of loss, if any, that may result from these actions. |

Stockholders' Equity Note [Abstract] | |
Stockholders' Equity | Note 11. Stockholders’ Equity Common Stock On January 3, 2023, the Company effected a 1-for-25 reverse stock split of the Company's common stock. The Reverse Stock Split, which has been retroactively reflected throughout this report, reduced the authorized shares of the Company to 164,000,000 and did not change the par value of the Company's common stock. PIPE Financings In February 2021, the Company entered into a Securities Purchase Agreement for a private placement with certain institutional and accredited investors (“February Purchasers”). Pursuant to the Securities Purchase Agreement, the February Purchasers purchased an aggregate of 174,825 units (“February Units”), representing (i) 174,825 shares of the Company’s common stock and (ii) warrants to purchase up to 174,825 shares of common stock. The purchase price for each February Unit was $ 143.00 , for an aggregate purchase price of approximately $ 25.0 million. The warrants are exercisable for cash at an exercise price of $ 171.50 per share, subject to adjustments as provided under the terms of the warrants. The warrants were immediately exercisable and expire on the fifth anniversary of the date of issuance. Pursuant to ASC 815-40, Derivatives and Hedging – Contracts in Entity’s Own Equity ("ASC 815"), the Company deemed the warrants to be liability classified and allocated the proceeds from issuance between the warrants and common stock using the with-and-without method. $ 12.8 million of the proceeds, equal to the fair value of the warrants determined using the Black-Scholes Model, were allocated to the warrant liability, and the remaining proceeds of $ 12.2 million were allocated to the common stock. The Company incurred a total of $ 1.4 million in issuance costs, which were allocated between the warrants and common stock on a relative fair value basis, $ 0.5 million and $ 0.9 million, respectively. The warrant liability was remeasured at $ 10.2 million as of March 31, 2021 and the Company recognized a gain on warrant liability in the amount of $ 2.6 million associated with this transaction during the three months ended March 31, 2021. On April 1, 2021, the registration statement to register the shares of common stock underlying the warrants was declared effective by the SEC. As a result, the warrants met the conditions to be classified in equity and the related warrant liability was reclassified from liability to equity on April 1, 2021. In June 2021, the Company entered into a Securities Purchase Agreement for a private placement with certain institutional and accredited investors (“June Purchasers”). Pursuant to the Securities Purchase Agreement, the June Purchasers purchased an aggregate of 647,773 units (“June Units”), representing (i) 627,773 shares of the Company’s common stock (ii) warrants to purchase up to 647,773 shares of common stock and (iii) pre-funded warrants to purchase up to 20,000 shares of common stock. The purchase price for each June Unit was $ 61.75 , for an aggregate purchase price of approximately $ 40.0 million. The warrants are exercisable for cash at an exercise price of $ 71.00 per share, subject to adjustments as provided under the terms of the warrants. The warrants were immediately exercisable and expire on the fifth anniversary of the date of issuance. The pre-funded warrants are exercisable at an exercise price of $ 0.025 per share and have no expiration date. In July 2021, the Company issued 20,000 shares of common stock as a result of the exercise of the outstanding pre-funded warrants at an exercise price of $ 0.025 per share. During the year ended December 31, 2021, the Company issued 243,886 shares of common stock as a result of the exercise of outstanding warrants at an exercise price of $ 71.00 per share for proceeds of $ 17.3 million. Pursuant to ASC 815, the Company deemed the warrants to be liability classified and allocated the proceeds from issuance between the warrants and common stock using the with-and-without method. $ 26.6 million of the proceeds, equal to the fair value of the warrants determined using the Black-Scholes Model, were allocated to the warrant liability, and the remaining proceeds of $ 13.4 million were allocated to the common stock. The Company incurred a total of $ 2.1 million in issuance costs, which were allocated between the warrants and common stock on a relative fair value basis, $ 0.7 million and $ 1.4 million, respectively. The warrant liability was remeasured at $ 31.8 million as of June 30, 2021 and the Company recognized a loss on warrant liability in the amount of $ 5.1 million in the consolidated statements of operations during the three months ended June 30, 2021. On June 30, 2021, the registration statement to register the shares of common stock underlying the warrants was declared effective by the SEC. As a result, the warrants met the conditions to be classified in equity and the related warrant liability was reclassified from liability to equity on June 30, 2021. Registered Offerings In August 2021, the Company issued and sold an aggregate of (i) 1,600,000 shares of common stock and (ii) warrants to purchase 1,600,000 shares of common stock in an underwritten public offering. Each share was sold together with one warrant to purchase one share of common stock at a combined public offering price of $ 25.00 per share of the common stock and the accompanying warrant. The warrants have an exercise price of $ 25.00 per share, are exercisable at any time, and will expire five years following the date of issuance. In addition, the Company granted the underwriter a 30-day option to purchase up to 240,000 shares of common stock ("Overallotment Stock Option") and/or warrants to purchase 240,000 shares of common stock (“Overallotment Warrant Option”) at a price of $ 24.75 per share of common stock and/or $ 0.25 per warrant. The warrants and Overallotment Warrant Options were issued in the money based on the public offering terms. The Company received approximately $ 37.4 million in net proceeds, after deducting underwriting discounts and commissions and other offering expenses payable by the Company. Pursuant to ASC 815, the Company deemed the Overallotment Stock Option to meet the scope exception for equity classification, and the warrants and Overallotment Warrant Option to be classified as a liability (collectively "the Warrant Liability") at fair value initially with subsequent changes in fair value recorded in earnings. The warrants were recorded at a fair value of $ 41.8 million and the Overallotment Warrant Option at a fair value of $ 6.2 million, both determined using the Black-Scholes Model. As the total fair value of the Warrant Liability exceeds the total proceeds of $ 37.4 million, the Company recorded a loss of the $ 8.1 million excess to gain (loss) on warrant liabilities in the consolidated statements of operations. Accordingly, there were no proceeds allocated to the common stock issued or the Overallotment Stock Option granted as part of this transaction. The Company incurred a total of $ 2.8 million in issuance costs, which were allocated between the warrants, Overallotment Warrant Option, common stock and Overallotment Stock Option on a relative fair value basis. The Overallotment Warrant Option was partially exercised in August for warrants to purchase an aggregate of 77,280 shares of common stock and the Company recognized a gain on the warrant liability in the amount of $ 3.4 million in the consolidated statements of operations. The remaining Overallotment Warrant Option expired in September 2021 and the Company recognized a gain of $ 1.9 million in the consolidated statements of operations. The Warrant Liability was remeasured at $ 18.7 million as of December 31, 2021 and the Company recognized a loss on warrant liability in the amount of $ 6.7 million in the consolidated statements of operations during the year ended December 31, 2021. The Warrant Liability was remeasured at $ 0.5 million as of December 31, 2022 and the Company recognized a gain on warrant liability in the amount of $ 18.2 million in the consol idated statements of operations during the year ended December 31, 2022. During the year ended December 31, 2021, the Company issued 1,147,365 shares of c ommon stock as a result of the exercise of outstanding warrants at an exercise price of $ 25.00 per share for proceeds of $ 28.7 million. The Warrant Liability was remeasured upon exercise of the warrants throughout the period, resulting in a loss on warrant liability in the amount of $ 41.6 million in the consolidated statements of operations during the year ended December 31, 2021. In October 2021, the Company entered into a securities purchase agreement with certain institutional and accredited investors for the purchase and sale of 533,333 shares of the Company's common stock, at a purchase price of $ 37.50 per share in a registered direct offering. The Company received approximately $ 18.7 million in net proceeds, after deducting placement agent fees and other offering expenses payable by the Company. In November 2022, the Company entered into a securities purchase agreement with certain institutional and accredited investors relating to the offering and sale of an aggregate of (i) 1,300,250 shares of common stock and (ii) warrants to purchase 1,300,250 shares of common stock in registered direct offering (the “November 2022 Offering”). Each share was sold together with one warrant to purchase one share of common stock at a combined public offering price of $ 7.50 per share of the common stock and the accompanying warrant. The Company received approximately $ 9.0 million in net proceeds, after deducting placement agent fees and offering expenses. Approximately $ 3.8 million of the gross proceeds were received in the form of a waiver of the Company's December 1, 2022 interest payment on the Convertible Notes. The warrants have an exercise price of $ 8.22 per share, are exercisable six months following the date of issuance, and will expire five years following the initial exercise date. Additionally, the Company agreed with certain institutional investors to amend outstanding warrants previously issued (i) in the February Units to purchase up to 104,895 shares of common stock with an exercise price of $ 171.50 per share and (ii) in the June Units to purchase up to 403,887 shares of common stock with an exercise price of $ 71.00 per share. Accordingly, the Company agreed to (i) lower the exercise price of such existing warrants to $ 8.22 per share, (ii) provide that such existing warrants, as amended, will not be exercisable until May 9, 2023 and (iii) extend the original expiration date of such existing warrants to May 9, 2028. Pursuant to ASC 815, the Company deemed the new warrants to be classified as a liability at fair value initially with subsequent changes in fair value recorded in earnings. The warrants were recorded at a fair value of $ 6.0 million determined using the Black-Scholes Model. As the total fair value of the warrant liability and common stock exceeds the in-kind payment proceeds of $ 3.8 million, the Company recorded an extinguishment loss of the $ 1.6 million excess to other income, net in the consolidated statements of operations. The warrant liability was remeasured at $ 3.0 million as of December 31, 2022 and the Company recognized a gain on warrant liability in the amount of $ 3.0 million in the consolidated statements of operations during the year ended December 31, 2022 . The Company incurred a total of $ 0.8 million in issuance costs, which were allocated between the warrants and common stock on a relative fair value basis. The modified warrants are equity classified both before and after the modification and were fair valued as of the date of the amendment, this resulted in an increase in the value of the warrants and an additional $ 0.9 million was recorded to additional paid in capital on the consolidated balance sheet. At-The-Market Sales Agreement and Offering In November 2021, the Company entered into an At Market Issuance Sales Agreement ("ATM Sale Agreement") with B. Riley Securities, Inc., BTIG, LLC, and H.C. Wainwright & Co. LLC ("Agents"), pursuant to which the Company may offer and sell shares of common stock having an aggregate offering price of up to $ 90.0 million from time to time, in “at the market” offerings through the Agents. In connection with the November 2022 Offering, the aggregate price was reduced to $ 70.0 million. Sales of the shares of common stock, if any, will be made at prevailing market prices at the time of sale, or as otherwise agreed with the Agents. The Agents will receive a commission from the Company of up to 3.0 % of the gross proceeds of any shares of common stock sold under the ATM Sale Agreement. During the three months ended December 31, 2021, the Company received net proceeds of $ 4.6 million, after deducting commissions and other offering expenses, from the sale of 70,550 shares under the ATM Sale Agreement. The Company sold such shares at a weighted average purchase price of $ 71.00 per share. During the three months ended December 31, 2022 , the Company received net proceeds of $ 0.6 million, after deducting commissions and other offering expenses, from the sale of 52,620 shares under the ATM Sale Agreement. The Company sold such shares at a weighted average purchase price of $ 10.93 per share. During the year ended December 31, 2022 , the Company received net proceeds of $ 7.1 million, after deducting commissions and other offering expenses, from the sale of 317,155 shares under the ATM Sale Agreement. The Company sold such shares at a weighted average purchase price of $ 30.27 per share. Preferred Stock Pursuant to the Company’s eighth amended and restated certificate of incorporation, which went into effect immediately prior to the completion of the IPO, the Company was authorized to issue 10,000,000 shares of undesignated preferred stock. This amount and the par value of preferred stock remained unchanged after the reverse stock split. On November 10, 2022, the Board declared a dividend of one one-thousandth of a share of Series X Preferred Stock, par value $ 0.001 per share (“Series X Preferred Stock”), for each outstanding share of common stock to stockholders of record as of November 21, 2022. This Series X Preferred Stock entitled its holders to 3,000 votes per share exclusively on the vote for the proposal to approve the Reverse Stock Split. All shares of Series X Preferred Stock that were not present to vote on the Reverse Stock Split were redeemed by the Company (the “Initial Redemption”). Any outstanding shares of Series X Preferred Stock that were not redeemed pursuant to an Initial Redemption would be redeemed in whole, but not in part, (i) if such redemption is ordered by the Board in its sole discretion, automatically and effective on such time and date specified by the Board in its sole discretion or (ii) automatically upon the effectiveness of the Certificate of Amendment implementing the Reverse Stock Split. At the December 19, 2022 special meeting of the Company's stockholders, the holders of 136,961 shares of Series X Preferred Stock were represented in person or by proxy. Immediately prior to the special meeting, all 86,210 shares of Series X Preferred Stock that were not voted were redeemed.

The Company periodically evaluates the recoverability of the deferred assets. At such time as it is determined that it is more likely than not that the deferred tax asset will be realized, the valuation allowance will be reduced. The change in the valuation allowance for the year ended December 31, 2022 was an increase of $ 11.8 million. At December 31, 2022 , the Company had federal and state income tax net operating loss (“NOL”) carryforwards of approximately $ 504.9 million and $ 246.3 million, respectively.

Pursuant to Section 382 and Section 383 of the Internal Revenue Code, annual use of the Company’s net operating loss carryforwards and tax credit carryforwards may be limited as a result of cumulative changes of ownership resulting in a change of control of the Company.

The Company has not updated their 382 study since the IPO offering 2020. Any future changes may limit future utilization of tax attribute carryforwards. Due to the existence of the valuation allowance, limitations created by future ownership changes, if any, will not impact the Company's effective tax rate. In accordance with ASC 740-10, Income Taxes—Overall, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more likely than not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50 % likelihood of being sustained . The Company has no uncertain tax positions at December 31, 2022. The Company is subject to taxation in the United States, various U.S. state jurisdictions. Multiple tax years remain open to examination depending on the applicable jurisdiction. The Company’s policy is to recognize interest and penalties related to income tax matters in the provision for income taxes.

The consolidated financial statements include the accounts of Biora Therapeutics, Inc., its wholly-owned subsidiaries, and, for the year ended December 31, 2021, an affiliated professional partnership with Avero with respect to which the Company had a specific management arrangement (see Note 3). All significant intercompany balances and transactions have been eliminated in consolidation. The consolidated financial statements and notes thereto give retrospective effect to the Reverse Stock Split for all periods presented. All common stock, options exercisable for common stock, restricted stock units, warrants and per share amounts contained in the consolidated financial statements have been retrospectively adjusted to reflect the Reverse Stock Split for all periods presented. Concurrent with the Reverse Stock Split the Company effected a reduction in the number of authorized shares of common stock from 350,000,000 shares to 164,000,000 shares. Financial Statement Presentation Change In order to more closely align with the Company’s business, and to better serve financial statement users, the Company has combined selling and marketing expenses with general and administrative expenses into a single selling, general and administrative expense line item. The Company's previous marketing expenses were associated with our discontinued Laboratory Operations and the Company no longer incurs these costs. Prior period amounts have been reclassified to conform to the current presentation. |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates include the estimate of variable consideration in connection with the recognition of revenue, the valuation of stock options, the valuation of goodwill, the valuation of the derivative liability associated with the Convertible Notes, accrual for reimbursement claims and settlements, the valuation of warrant liabilities, the valuation of assets held for sale, assessing future tax exposure and the realization of deferred tax assets, and the useful lives and the recoverability of property and equipment. The Company bases these estimates on historical and anticipated results, trends, and various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities and recorded revenues and expenses that are not readily apparent from other sources. Actual results could differ from those estimates and assumptions. |
Operating Segments | Operating Segments Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker or decision-making group in making decisions on how to allocate resources and assess performance. The Company views its operations and manages its business as one operating segment. All revenues are attributable to U.S.-based operations and all assets are held in the United States. |
Assets Held for Sale and Discontinued Operations | Assets Held for Sale and Discontinued Operations Assets and liabilities are classified as held for sale when all of the following criteria for a plan of sale have been met: (1) management, having the authority to approve the action, commits to a plan to sell the assets; (2) the assets are available for immediate sale, in their present condition, subject only to terms that are usual and customary for sales of such assets; (3) an active program to locate a buyer and other actions required to complete the plan to sell the assets have been initiated; (4) the sale of the assets is probable and is expected to be completed within one year; (5) the assets are being actively marketed for a price that is reasonable in relation to their current fair value; and (6) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or the plan will be withdrawn. When all of these criteria have been met, the assets and liabilities are classified as held for sale in the consolidated balance sheet. Assets classified as held for sale are reported at the lower of their carrying value or fair value less costs to sell. Depreciation and amortization of assets ceases upon designation as held for sale. Discontinued operations comprise activities that were disposed of, discontinued or held for sale at the end of the period, represent a separate major line of business that can be clearly distinguished for operational and financial reporting purposes and represent a strategic business shift having a major effect on the Company’s operations and financial results according to Accounting Standard Codification (“ASC”) Topic 205, Presentation of Financial Statements . Additional details surrounding the Company's assets and liabilities held for sale and discontinued operations are included in Note 4 . |
Investments | Investments The Company accounts for investments in equity securities without a readily determinable fair value at cost, minus impairment. If the Company identifies observable price changes in orderly transactions for an identical or a similar investment of the same issuer, the Company will measure the equity security at fair value as of the date that the observable transaction occurred in accordance with ASC Topic 321, Investments-Equity Securities . |
Revenue Recognition | Revenue Recognition Revenue is recognized in accordance with the Financial Accounting Standards Board (“FASB”) ASC Topic 606 , Revenue from Contracts with Customers (“ASC 606”). In accordance with ASC 606, the Company follows a five-step process to recognize revenues: 1) identify the contract with the customer, 2) identify the performance obligations, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations and 5) recognize revenues when the performance obligations are satisfied. Revenue was primarily derived from providing molecular testing products, which were reimbursed through arrangements with third-party payors, laboratory distribution partners, and amounts from individual patients. Third-party payors include commercial payors, such as health insurance companies, health maintenance organizations and government health benefit programs, such as Medicare and Medicaid. The Company’s contracts generally contained a single performance obligation, which was the delivery of the test results, and the Company satisfied its performance obligation at a point in time upon the delivery of the results, which then triggered the billing for the product. The amount of revenue recognized reflects the amount of consideration the Company expected to be entitled to ("transaction price") and considered the effects of variable consideration. Revenue was recognized when control of the promised product was transferred to customers, in an amount that reflected the consideration the Company expected to be entitled to in exchange for those products. The Company applies the following practical expedients and exemptions: • Incremental costs incurred to obtain a contract are expensed as incurred because the related amortization period would be one year or less. The costs are included in selling and marketing expenses. • No adjustments to amounts of promised consideration are made for the effects of a significant financing component because the Company expects, at contract inception, that the period between the transfer of a promised good or service and customer payment for that good or service will be one year or less. |
Payor Concentration | Payor Concentration The Company historically relied upon reimbursements from third-party government payors and private-payor insurance companies to collect accounts receivable. As a result of the Strategic Transformation, all revenue from Laboratory Operations has been classified as discontinued operations and there were no significant concentrations as of December 31, 2022. The Company’s significant third-party payors and their related accounts receivable balances and revenues as a percentage of total accounts receivable balances as of December 31, 2021 and of revenues for the year ended December 31, 2021 are as follows: Percentage of Accounts Receivable December 31, 2021 Blue Shield of Texas 4.0 % United Healthcare 7.2 % Government Health Benefits Programs 55.8 % Percentage of Revenue (1) Year Ended December 31, 2021 Blue Shield of Texas 10.7 % Aetna 7.3 % Cigna 5.7 % United Healthcare 6.7 % Government Health Benefits Programs 23.2 % (1) Percentage of revenue table shows amounts as a percentage of total revenue, including revenue classified as discontinued operations. Refer to Note 5 for details of the breakdown of revenue. |
Accounts Receivable | Accounts Receivable Amounts included in accounts receivable for the year ended December 31, 2021 consist of receivables generated from the Company's genetics laboratory in Ann Arbor, Michigan. The Company continued to collect these receivables and did not include these amounts as assets held for sale. The accounts receivable amounts were recorded at the transaction price and considered the effects of variable consideration. The total consideration the Company expected to collect was an estimate and was fixed or variable. Variable consideration included reimbursement from third-party payors, laboratory distribution partners, and amounts from individual patients, and was adjusted for disallowed cases, discounts, and refunds using the expected value approach. The Company monitors these estimates at each reporting period based on actual cash collections in order to assess whether a revision to the estimate is require d. |
Cash and Cash Equivalents including Concentration of Credit Risk | Cash and Cash Equivalents including Concentration of Credit Risk The Company considers all highly liquid investment instruments purchased with an initial maturity of three months or less to be cash equivalents. The Company limits its exposure to credit loss by placing its cash and cash equivalents in financial institutions with high credit ratings. The Company’s cash and cash equivalents may consist of deposits held with banks, money market funds, or other highly liquid investments that may at times exceed federally insured limits. Cash equivalents are financial instruments that potentially subject the Company to concentrations of risk, to the extent of amounts recorded in the balance sheets. The Company performs evaluations of its cash equivalents and the relative credit standing of these financial institutions and limits the amount of credit exposure with any one institution. Management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. |
Property and Equipment, Net | Property and Equipment, Net Property and equipment are stated at cost. Assets acquired under capital leases are stated at the present value of future minimum lease payments. Depreciation is recognized on a straight-line basis over the estimated useful lives of the related assets as follows: Property and Equipment Estimated Useful Life (in years) Computers and software 3 Laboratory equipment 5 Furniture, fixtures, and office equipment 8 Building 15 Assets acquired under capital leases and leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or the useful life of the asset. Land is not depreciated. |
Leases | Leases The Company determines if an arrangement is or contains a lease at inception. For leases with a term greater than one year, lease right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the net present value of lease payments, the Company uses its incremental borrowing rate which represents an estimated rate of interest that the Company would have to pay to borrow equivalent funds on a collateralized basis at the lease commencement date. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the statement of operations. |
Goodwill | Goodwill Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill is not amortized but instead is tested annually for impairment at the reporting unit level, or more frequently when events or changes in circumstances indicate that fair value of the reporting unit has been reduced to less than its carrying value. The Company may choose to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a quantitative assessment. If a quantitative assessment is deemed necessary, the Company compares the fair value of the reporting unit with its carrying amount, including goodwill. An impairment loss will be recognized if the reporting unit’s carrying amount exceeds its fair value, to the extent that it does not exceed the total carrying amount of goodwill. No impairment existed as of December 31, 2022 or December 31, 2021 . |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company accounts for the impairment of long-lived assets, such as property and equipment, by reviewing these assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group to be tested for possible impairment, the Company first compares undiscounted future cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted-cash-flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. The Company recorded impairment of $ 0.5 million during the year ended December 31, 2022 . No impairment was recorded for the year ended December 31, 2021 . |
Fair Value of Financial Instruments | Fair Value of Financial Instruments The Company’s financial assets and liabilities are carried at fair value or at amounts that, because of their short-term nature, approximate current fair value, with the exception of its Convertible Notes, which are carried at amortized cost. The carrying value of the Company’s accounts receivable, accounts payable, and accrued expenses and other current liabilities are considered to be representative of their respective fair values because of their short-term nature (see Note 7 ). |
Embedded Derivative Related to Convertible Notes | Embedded Derivative Related to Convertible Notes In December 2020, the Company issued Convertible Notes with an embedded derivative that was required to be bifurcated from the host contract and remeasured to fair value at each balance sheet date. Any resulting gain or loss related to the change in the fair value of the embedded derivative was recorded to other income, net in the consolidated statements of operations. As of December 31, 2022, the conversion option has expired and the Company no longer has an embedded derivative. |
Common Stock Warrant Liability | Common Stock Warrant Liabilities The Company accounts for common stock warrants issued as freestanding instruments in accordance with applicable accounting guidance as either liabilities or as equity instruments depending on the specific terms of the warrant agreements. Warrants classified as liabilities are remeasured each period until settled or until classified as equity. Any resulting gain or loss related to the changes in the fair value of the warrant liabilities are recorded to gain (loss) on warrant liabilities in the consolidated statements of operations. Changes in the Company’s inputs and assumptions, such as the Company’s stock price and volatility of common stock, could result in material changes in the valuation in future periods. |
Repair and Maintenance | Repairs and Maintenance The Company incurs maintenance costs on its major equipment. Repair and maintenance costs are expensed as incurred. |
Research and Development | Research and Development Research and development expenses consist primarily of costs associated with performing research and development activities to develop new products. Research and development expenses also consist of personnel expenses, including salaries, bonuses, stock-based compensation expense, and benefits, and allocated overhead costs. Research and development expenses are expensed as incurred. |
Selling, General and Administrative | Selling, General and Administrative Selling, general and administrative expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation expense, and benefits, for the Company's finance and accounting, legal, human resources, and other administrative teams. Additionally, these expenses include costs for communication, advertising, conferences, and professional fees of audit, legal, and recruiting services. Selling, general and administrative expenses are expensed as incurred. Advertising expense for the year ended December 31, 2021 was $ 0.6 million, and there were no advertising expenses for the year ended December 31, 2022 . |
Stock-Based Compensation | Stock-Based Compensation Stock-based compensation related to stock options, restricted stock units (“RSUs”) and the 2020 Employee Stock Purchase Plan (“ESPP”) awards granted to the Company’s employees is measured at the grant date based on the fair value of the award. The fair value is recognized as expense over the requisite service period, which is generally the vesting period of the respective awards. Compensation related to service-based awards is recognized starting on the grant date on a straight-line basis over the vesting period, which is typically four years . For the ESPP, the requisite service period is generally the period of time from the offering date to the purchase date. In addition, the Company grants stock option awards that vest upon achievement of certain performance criteria ("Performance Awards"). The fair value is recognized as expense over the requisite service period when the Company has concluded that achieving the performance criteria is probable. The probability of achieving the performance criteria is assessed each reporting period. The Company accounts for the forfeitures in the period in which they occur. The fair value of RSUs is estimated based on the closing price of the Company's common stock on the date of the grant. The fair value of stock options, ESPP awards and Performance Awards is estimated using the Black-Scholes option-pricing model and is affected by the Company’s assumptions regarding a number of complex and subjective variables. These variables include, but are not limited to, the fair value of the common stock at the date of grant, the expected term of the awards, the expected stock price volatility over the term of the awards, risk-free interest rate, and dividend rate. The Company’s inputs and assumptions with respect to these variables are as follows: Fair Value of Common Stock — Prior to the IPO, the Company’s common stock was not publicly traded, therefore the Company estimated the fair value of its common stock. Following the initial public offering of the Company's common stock (the "IPO"), the fair value of the Company’s common stock for awards with service-based vesting is the closing price of its common stock on the date of grant or other relevant determination date. Expected Term —The expected term represents the period that the stock-based awards are expected to be outstanding. The Company determines the expected term using the simplified method. The simplified method deems the term to be the average of the time-to-vesting and the contractual life of the options. For stock options granted to non-employees, the expected term equals the remaining contractual term of the option from the vesting date. For the ESPP, the expected term is the period of time from the offering date to the purchase date. Expected Volatility —Given the limited period of time the Company’s stock has been traded in an active market, the expected volatility is estimated by taking the average historical volatility for industry peers, consisting of several public companies in the Company’s industry that are similar in size, stage, or financial leverage, over a period of time commensurate with the expected term of the awards. Risk-Free Interest Rate —The risk-free interest rate is calculated using the average of the published interest rates of U.S. Treasury zero-coupon issues with maturities that are commensurate with the expected term. Dividend Rate —The dividend yield assumption is zero , as the Company has no plans to pay dividends. |
Net Loss Per Share | Net Loss Per Share Basic net loss per share is computed by dividing the net loss by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing the net loss by the weighted average number of shares of common stock and potentially dilutive securities outstanding for the period. As the Company has reported net losses for all periods presented, all potentially dilutive securities are antidilutive and, accordingly, basic net loss per share equals diluted net loss per share. |
Income Taxes | Income Taxes The Company accounts for income taxes under the asset-and-liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50 % likely of being realized. Changes in recognition or measurement are recognized in the period in which the change in judgment occurs. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. |
Comprehensive Loss | Comprehensive Loss The Company did no t have any other comprehensive income or loss for any of the periods presented, and therefore comprehensive loss was the same as the Company’s net loss. |
Emerging Growth Company Status | Emerging Growth Company Status The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). Under the JOBS Act, EGCs can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. |
Recent Accounting Pronouncements Adopted | Recent Accounting Pronouncements Adopted In February 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) , which supersedes FASB ASC Topic 840, Leases (Topic 840) , and provides principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The Company adopted the provisions of this guidance on January 1, 2022, using the effective date method. As a result of adopting ASC 842, the Company recognized right-of-use assets and lease liabilities of $ 2.2 million and $ 2.2 million, respectively, on January 1, 2022. The difference between the right-of-use assets and lease liabilities is attribut ed to the elimination of deferred rent and prepaid rent. There was no adjustment to the opening balance of accumulated deficit as a result of the adoption. The Company elected to use the package of practical expedients available in the new lease standard, allowing it not to reassess: (a) whether expired or existing contracts contain leases under the new definition of a lease; (b) lease classification for expired or existing leases; and (c) whether previously capitalized initial direct costs would qualify for capitalization under the new lease standard. In May 2021, the FASB issued ASU No. 2021-04 , Issuer's Accounting for Certain Modification or Exchanges of Freestanding Equity-Classified Written Call Options , which provides a principles-based framework to determine whether an issuer should recognize the modification or exchange as an adjustment to equity or an expense. The Company adopted this standard on January 1, 2022 , which did not have a material impact on the consolidated financial statements. |
Recent Accounting Pronouncements Not Yet Adopted | Recent Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses , which requires the measurement of expected credit losses for financial instruments carried at amortized cost, such as accounts receivable, held at the reporting date based on historical experience, current conditions and reasonable forecasts. The main objective of this standard is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financing Instruments–Credit Losses , which included an amendment of the effective date. The standard is effective for the Company for annual reporting periods beginning after December 15, 20 22. The Company does not expect the adoption of this standard to have a significant impact on its consolidated financial statements. In August 2020, the FASB issued ASU No. 2020-06 , Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40)-Accounting for Convertible Instruments and Contracts in an Entity's Own Equity , which simplifies the accounting for convertible instruments, amends the guidance on derivative scope exceptions for contracts in an entity's own equity, and modifies the guidance on diluted earnings per share calculations as a result of these changes. The standard is effective for the Company for annual reporting periods beginning after December 15, 2023. The Company is currently evaluating the impact the adoption of this standard may have on its consolidated financial statements. |
