Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (U.S. GAAP) and include the accounts of our wholly owned subsidiaries. As of June 30, 2019 , we had wholly owned subsidiaries in Singapore, Canada, the Netherlands, Japan, France, the United Kingdom, China, and Germany. All subsidiaries, except for Singapore, use their local currency as their functional currency. The Singapore subsidiary uses the U.S. dollar as its functional currency. All intercompany transactions and balances have been eliminated in consolidation. Certain prior period amounts in the condensed consolidated statements of cash flows were reclassified to conform with the current period presentation. These reclassifications were immaterial and did not affect prior period total assets, total liabilities, stockholders' equity, total revenue, total costs and expenses, loss from operations or net loss. Net Loss per Share Our basic and diluted net loss per share is calculated by dividing net loss by the weighted-average number of shares of common stock outstanding for the period. Restricted stock units, options to purchase common stock, and shares associated with the potential conversion of our convertible notes are considered to be potentially dilutive common shares but have been excluded from the calculation of diluted net loss per share as their effect is anti-dilutive for all periods presented. The following potentially dilutive common shares were excluded from the computation of diluted net loss per share for the three and six months ended June 30, 2019 , and 2018 because including them would have been anti-dilutive (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Stock options, restricted stock units and performance awards 4,541 4,586 4,541 4,586 2018 Convertible Notes — 19,036 — 19,036 2018 Convertible Notes potential make-whole shares — 1,204 — 1,204 2014 Convertible Notes 916 916 916 916 Total 5,457 25,742 5,457 25,742 Accumulated Other Comprehensive Loss The components of accumulated other comprehensive loss, net of tax, for the three and six months ended June 30, 2019 , are as follows (in thousands): Foreign Currency Translation Adjustment Net Unrealized Gain on Securities Accumulated Other Comprehensive Loss Balance at December 31, 2018 $ (687 ) $ — $ (687 ) Other comprehensive income 8 — 2 10 Balance at March 31, 2019 (679 ) 2 (677 ) Other comprehensive income (loss) (9 ) — 63 54 Balance at June 30, 2019 $ (688 ) $ 65 $ (623 ) Revenue Recognition We generate revenue primarily from the sale of our products and services. Product revenue is derived from the sale of instruments and consumables, including IFCs, assays and reagents. Service revenue is derived from the sale of instrument service contracts, repairs, installation, training and other specialized product support services. Revenue is reported net of any sales, use and value-added taxes we collect from customers as required by government authorities. We recognize revenue based on the amount of consideration we expect to receive in exchange for the goods and services we transfer to the customer. Our commercial arrangements typically include multiple distinct products and services, and we allocate revenue to these performance obligations based on their relative standalone selling prices. Standalone selling prices (SSP) are generally determined using observable data from recent transactions. In cases where sufficient data is not available, we estimate a product’s SSP using a cost plus a margin approach or by applying a discount to the product’s list price. Product Revenue We recognize product revenue at the point in time when control of the goods passes to the customer and we have an enforceable right to payment. This generally occurs either when the product is shipped from one of our facilities or when it arrives at the customer’s facility, based on the contractual terms. Customers generally do not have a unilateral right to return products after delivery. Invoices are generally issued at shipment and generally become due in 30 to 60 days. We sometimes perform shipping and handling activities after control of the product passes to the customer. We have made an accounting policy election to account for these activities as product fulfillment activities rather than as separate performance obligations. Service Revenue We recognize revenue from repairs, installation, training and other specialized product support services at the point in time the work is completed. Installation and training services are generally billed in advance of service. Repairs and other services are generally billed at the point the work is completed. Revenue associated with instrument service contracts is recognized on a straight-line basis over the life of the agreement, which is generally one to three years. We believe this time-elapsed approach is appropriate for service contracts because we provide services on demand throughout the term of the agreement. Invoices are generally issued in advance of service on a monthly, quarterly, annual or multi-year basis. Payments made in advance of service are reported on our consolidated balance sheet as deferred revenue. Contract Costs Incremental sales commission costs incurred to obtain instrument service contracts are capitalized and amortized to selling, general and administrative expense over the life of the contract, which is generally one to three years. As a practical expedient, we expense sales commissions associated with product support services that are delivered in less than one year as they are incurred. Sales commissions associated with the sale of products are expensed as they are incurred. Product Warranties We generally provide a one-year warranty on our instruments. We accrue for estimated warranty obligations at the time of product shipment. We periodically review our warranty liability and record adjustments based on the terms of warranties provided to customers, and historical and anticipated warranty claim experience. This expense is recorded as a component of cost of product revenue in the condensed consolidated statements of operations. Significant Judgments Applying the revenue recognition practices discussed above often requires significant judgment. Judgment is required when identifying performance obligations, estimating SSP and allocating purchasing consideration in multi-element arrangements and estimating the future amount of our warranty obligations. Moreover, significant judgment is required when interpreting commercial terms and determining when control of goods and services passes to the customer. Any material changes created by errors in judgment could have a material effect on our operating results and overall financial condition. Goodwill, Intangible Assets, and Other Long-lived Assets Goodwill, which has an indefinite useful life, represents the excess of cost over fair value of net assets acquired. Our intangible assets include developed technology, patents and licenses. The cost of identifiable intangible assets with finite lives is generally amortized on a straight-line basis over the assets’ respective estimated useful lives. Goodwill and intangible assets with indefinite lives are not subject to amortization but are tested for impairment on an annual basis during the fourth quarter or whenever events or changes in circumstances indicate the carrying amount of these assets may not be recoverable. We first conduct an assessment of qualitative factors to determine whether it is more likely than not that the fair value of our reporting unit is less than its carrying amount. If we determine that it is more likely than not that the fair value of our reporting unit is less than its carrying amount, we then conduct a two-step test for impairment of goodwill. In the first step, we compare the fair value of our reporting unit to its carrying value. If the fair value of our reporting unit exceeds its carrying value, goodwill is not considered impaired and no further analysis is required. If the carrying value of the reporting unit exceeds its fair value, then the second step of the impairment test must be performed in order to determine the implied fair value of the goodwill. If the carrying value of the goodwill exceeds its implied fair value, then an impairment loss equal to the difference would be recorded. We evaluate our long-lived assets, including finite-lived intangibles, for indicators of possible impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. If any indicator of impairment exists, we assess the recoverability of the affected long-lived assets by determining whether the carrying value of the asset can be recovered through undiscounted future operating cash flows. If impairment is indicated, we estimate the asset’s fair value using future discounted cash flows associated with the use of the asset and adjust the carrying value of the asset accordingly. We did not recognize any impairment of long-lived assets for any of the periods presented herein. Convertible Notes In February 2014, we closed an underwritten public offering of $201.3 million aggregate principal amount of our 2.75% Senior Convertible Notes due 2034 (2014 Notes). In March 2018, we entered into separate privately negotiated transactions with certain holders of our 2014 Notes to exchange $150.0 million in aggregate principal amount of the 2014 Notes for our new 2.75% Exchange Convertible Senior Notes due 2034 (2018 Notes). Following the exchange, approximately $51.3 million in aggregate principal amount of the 2014 Notes was outstanding in addition to $150.0 million in aggregate principal amount of the 2018 Notes. In the first quarter of 2019, the 2018 Notes were converted into 19.5 million shares of common stock and the 2018 Notes were retired. We recorded a loss of $9.0 million on the retirement of the 2018 Notes. See Note 6 Convertible Notes and Credit Facility for the accounting treatment of the transactions and additional information about the exchange. Recent Accounting Changes and Accounting Pronouncements Adoption of New Accounting Guidance In February 2016, the FASB established Topic 842, Leases, by issuing Accounting Standards Update (ASU) No. 2016-02, which requires lessees to recognize operating leases on the balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use (ROU) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases are classified as finance or operating; the classification will impact the expense recognition in the income statement. Modified Retrospective Transition approach is required, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. We adopted the new standard on January 1, 2019 and used the effective date of the standard as our date of initial application. Consequently, previously presented financial information has not been updated, and the disclosures required under the new standard have not been provided for dates and periods before January 1, 2019. For dates and periods prior to January 1, 2019, the original disclosures under ASC 840 are disclosed. The new standard provides several optional practical expedients in transition. We elected the ‘package of practical expedients,’ which permits us to not reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. We did not elect the use-of-hindsight or the practical expedient pertaining to land easements; the latter not being applicable to us. On adoption, we recognized $9.2 million of lease liabilities, based on the present value of the current minimum lease payments over the lease term, discounted using our collateralized incremental borrowing rate, with corresponding ROU assets of $ 7.4 million . The difference between the initial lease liability and ROU asset is attributable to deferred rent. There was no impact to retained earnings from the adoption of ASC 842. The new standard also provides certain accounting elections for an entity’s ongoing accounting. We have elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, we will not recognize ROU assets or lease liabilities for leases with an initial lease term of one year or less. We have also elected to not separate lease and nonlease components for our building leases. The nonlease components are generally variable in nature and are expected to comprise most of our variable lease costs. Variable costs are expensed as incurred. We have taken a portfolio approach for our vehicle leases by country. Recent Accounting Pronouncements In August 2018, the FASB issued ASU 2018-15 Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) which establishes new guidance on the accounting for costs incurred to implement a cloud computing arrangement that is considered a service arrangement. The new guidance requires the capitalization of such costs, aligning it with the accounting for costs associated with developing or obtaining internal-use software. The new guidance is effective for fiscal years beginning after December 15, 2019. We are currently evaluating the impact of adoption on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The ASU eliminates the requirement for an entity to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, an entity performs its annual, or interim, goodwill impairment testing by comparing the fair value of a reporting unit with its carrying amount and recording an impairment charge for the amount by which the carrying amount exceeds the fair value. The ASU will be effective for annual and interim goodwill impairment testing performed for our fiscal year beginning January 1, 2020, with early adoption permitted. We are currently evaluating the effect that the updated standard will have on our consolidated financial statements. The FASB issued two ASUs related to financial instruments – credit losses. The ASUs issued were: (1) in June 2016, ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and (2) in November 2018, ASU 2018-19 Codification Improvements to Topic 326, Financial Instruments—Credit Losses. ASU 2016-13 is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. ASU 2018-19 clarifies that receivables arising from operating leases are not within the scope of the credit losses standard, but rather, should be accounted for in accordance with the leasing standard. These ASUs are effective for fiscal years beginning after December 15, 2019, and interim periods within those years, with early adoption permitted. We are evaluating the effect that ASU 2016‑13 and ASU 2018-19 will have on our consolidated financial statements and related disclosures. |

Convertible Notes and Credit Facility | Convertible Notes and Credit Facility 2014 Senior Convertible Notes (2014 Notes) In February 2014, we closed an underwritten public offering of $201.3 million aggregate principal amount of our 2.75% Senior Convertible Notes due 2034 (2014 Notes), pursuant to an underwriting agreement dated January 29, 2014. The 2014 Notes accrue interest at a rate of 2.75% per year, payable semi-annually in arrears on February 1 and August 1 of each year. Interest on the 2014 Notes accrued from February 4, 2014. The 2014 Notes will mature on February 1, 2034, unless earlier converted, redeemed, or repurchased in accordance with the terms of the 2014 Notes. The initial conversion rate of the 2014 Notes is 17.8750 shares of our common stock, par value $0.001 per share, per $1,000 principal amount of 2014 Notes (which is equivalent to an initial conversion price of approximately $55.94 per share). The conversion rate will be subject to adjustment upon the occurrence of certain specified events, including upon a conversion in connection with a fundamental change, as defined in the indenture governing the 2014 Notes or, subject to certain conditions, redemption of the 2014 Notes by the Company. Holders may surrender their 2014 Notes for conversion at any time prior to the stated maturity date. On or after February 6, 2018, and prior to February 6, 2021, we may redeem any or all of the 2014 Notes in cash if the closing price of our common stock exceeds 130% of the conversion price for a specified number of days, and on or after February 6, 2021, we may redeem any or all of the 2014 Notes in cash without any such condition. The redemption price of the 2014 Notes will equal 100% of the principal amount of the 2014 Notes plus accrued and unpaid interest. Holders may require us to repurchase all or a portion of their 2014 Notes on each of February 6, 2021, February 6, 2024, and February 6, 2029, at a repurchase price in cash equal to 100% of the principal amount of the 2014 Notes plus accrued and unpaid interest. If we undergo a fundamental change, as defined in the indenture governing the 2014 Notes, holders may require us to repurchase the 2014 Notes in whole or in part for cash at a repurchase price equal to 100% of the principal amount of the 2014 Notes plus accrued and unpaid interest. In February 2014, we received $195.2 million , net of underwriting discounts, from the issuance of the 2014 Notes and incurred approximately $1.1 million in offering-related expenses. The underwriting discount of $6.0 million and the debt issuance costs of $1.1 million were recorded as offsets to the proce eds. 2018 Senior Convertible Notes (2018 Notes) In March 2018, we entered into separate privately negotiated transactions with certain holders of our 2014 Notes to exchange $150.0 million in aggregate principal amount of the 2014 Notes for new convertible notes (2018 Notes). The 2018 Notes were subsequently retired in the first quarter of 2019 as discussed below. As of the closing of the 2018 Notes on March 12, 2018, the estimated fair value was $145.5 million . The difference between the $150.0 million aggregate principal amount of the 2018 Notes and its fair value was amortized over the expected term of the 2018 Notes using the effective interest method through the first note holder put date of February 6, 2023. We accounted for the exchange transaction as an extinguishment of debt due to the significance of the change in value of the embedded conversion option, resulting in a $0.1 million gain. The gain on extinguishment of the 2014 Notes exchanged was calculated as the difference between the reacquisition price (i.e., the fair value of the principal amount of 2018 Notes) and the net carrying value of the 2014 Notes exchanged, net of unamortized debt discount and debt issuance cost write-offs. The 2018 Notes accrued interest at a rate of 2.75% , payable semi-annually in arrears on February 1 and August 1 of each year. Interest on the 2018 Notes accrued from February 1, 2018. The 2018 Notes were set to mature on February 1, 2034, unless earlier converted, redeemed, or repurchased in accordance with the terms of the indenture governing the 2018 Notes. The initial conversion rate of the 2018 Notes was 126.9438 shares of our common stock, par value $0.001 per share, per $1,000 principal amount of the 2018 Notes (which is equivalent to an initial conversion price of approximately $7.88 per share). The conversion rate was subject to adjustment upon the occurrence of certain specified events. One of those specified events was that Holders who converted their 2018 Notes voluntarily prior to our exercise of the Issuer's Conversion Option were entitled, under certain circumstances, to a make-whole premium in the form of an increase in the conversion rate determined by reference to a make-whole table set forth in the indenture governing the 2018 Notes. Any time prior to the maturity of the 2018 Notes, we had the ability to convert the 2018 Notes, in whole but not in part, into cash, shares of our common stock, or combination thereof, if the closing price of our common stock equaled or exceeded 110% of the conversion price then in effect for a specified number of days (Issuer’s Conversion Option). On or after February 6, 2022, we would have been able to elect to redeem all or any portion of the 2018 Notes at a redemption price equal to 100% of the accreted principal amount of the 2018 Notes on the redemption date of the 2018 Notes, plus accrued and unpaid interest. Holders of the 2018 Notes had the right, at their option, to require us to purchase all or a portion of the 2018 Notes (i) on February 6, 2023, February 6, 2026, and February 6, 2029, or (ii) in the event of a fundamental change, as defined in the indenture governing the 2018 Notes, in each case, at a repurchase price equal to 100% of the accreted principal amount (i.e., up to 120% of the outstanding principal amount) of the 2018 Notes on the fundamental change repurchase date, plus accrued and unpaid interest. As the 2018 Notes were convertible, at our election, into cash, shares of our common stock, or a combination of cash and shares of our common stock, we accounted for the 2018 Notes under the cash conversion guidance in ASC 470, whereby the embedded conversion option in the 2018 Notes was separated and accounted for in equity. The embedded conversion option value was calculated as the difference between (i) the total fair value of the 2018 Notes and (ii) the fair value of a similar debt instrument excluding the embedded conversion option. We determined an embedded conversion option value of $29.3 million , which was recorded in additional paid-in-capital and reduced the carrying value of the 2018 Notes. The resulting discount on the 2018 Notes was amortized over the expected term of the 2018 Notes, using the effective interest method through the first note holder put date, of February 6, 2023. Offering-related costs for the 2018 Notes were approximately $2.8 million and were paid in the first and second quarters of 2018. Offering-related costs of $2.2 million were capitalized as debt issuance costs, recorded as an offset to the carrying value of the 2018 Notes, and are amortized over the expected term of the 2018 Notes using the effective interest method through the first note holder put date of February 6, 2023. Offering-related costs of $0.6 million were accounted for as equity issuance costs, recorded as an offset to additional paid-in capital, and are not subject to amortization. Offering-related costs were allocated between debt and equity in the same proportion as the allocation of the 2018 Notes between debt and equity. In the first quarter of 2019, we received notices from holders of the 2018 Notes electing to voluntarily convert approximately $138.1 million in aggregate principal amount of the 2018 Notes. In February 2019, we notified the Trustee of our intention to exercise our Issuer’s Conversion Option with respect to the remaining approximately $11.9 million in aggregate principal amount of 2018 Notes. In total, $150.0 million of the 2018 Notes were converted into 19.5 million shares of our common stock and the bonds were retired. We recognized a loss of $9.0 million , which represents the difference between the fair value of the bonds retired and their carrying costs. The net impact on equity was $133.3 million and represents the fair value of the bonds retired. The carrying values of the components of the 2014 Notes and the 2018 Notes are as follows (in thousands): June 30, 2019 December 31, 2018 2.75% 2014 Notes due 2034 Principal amount $ 51,250 $ 51,250 Unamortized debt discount (1,199 ) (1,232 ) Unamortized debt issuance cost (218 ) (224 ) $ 49,833 $ 49,794 2.75% 2018 Notes due 2034 Principal amount $ — $ 149,999 Premium accretion — 3,755 Unamortized debt discount — (29,558 ) Unamortized debt issuance cost — (1,932 ) $ — $ 122,264 $ 49,833 $ 172,058 2018 Revolving Credit Facility In August 2018, the Company entered into a revolving credit facility with Silicon Valley Bank (Revolving Credit Facility) in an aggregate principal amount of up to the lesser of (i) $15.0 million (Maximum Amount) or (ii) the sum of (a) 85% of our eligible receivables and (b) 50% of our eligible inventory, in each case, subject to certain limitations (Borrowing Base), provided that the amount of eligible inventory that may be counted towards the Borrowing Base shall be subject to a cap as set forth in the Revolving Credit Facility. Subject to the level of this borrowing base, the Company may make and repay borrowings from time to time until the maturity of the revolving credit facility. As of June 30, 2019 , availability under the revolving credit facilit y was $12.5 million . There were no borrowings outstanding under the Revolving Credit Facility at June 30, 2019 . The Revolving Credit Facility matures on August 2, 2020 and is collateralized by substantially all the Company’s property, other than intellectual property. Loans under the Revolving Credit Facility will bear interest, at the greater of (i) prime rate plus 0.50% or (ii) 5.50% . Interest on any outstanding loans is due and payable monthly and the principal balance is due at maturity though loans can be prepaid at any time without penalty. In addition, the Company pays a quarterly unused revolving line facility fee of .75% per annum on the average unused facility. Subject to certain exceptions, the Company must pay a prepayment fee equal to (i) 2.00% of the Maximum Amount if it prepays all advances and terminates the Loan Agreement prior to August 2, 2019, or (ii) 1.00% of the Maximum Amount if it prepays all advances and terminates the Loan Agreement on or after August 2, 2019, and prior to the maturity date. The Company incurred approximately $335,000 of debt issuance costs in connection with the facility, including $225,000 in commitment fees. Half of the commitment fee was paid at the inception of the facility with the remainder due on the earliest of (i) August 2, 2019, (ii) the date on which the Company terminates this Agreement or (iii) the occurrence and continuance of an event of default. Debt issuance costs were capitalized and are being amortized to interest expense over the life of the Revolving Credit Facility. The Revolving Credit Facility contains customary affirmative and negative covenants which, unless waived by the bank, limit the Company’s ability to, among other things, incur additional indebtedness, grant liens, make investments, repurchase stock, pay dividends, transfer assets, enter into affiliate transactions, undergo a change of control, or engage in merger and acquisition activity, including merging or consolidating with a third party. The Revolving Credit Facility also contains customary events of default, subject to customary cure periods for certain defaults, that include, among other things, non-payment defaults, covenant defaults, material judgment defaults, bankruptcy and insolvency defaults, cross-defaults to certain other material indebtedness, and defaults due to inaccuracy of representation and warranties. Upon an event of default, the lender may declare all or a portion of the outstanding obligations payable by the Company to be immediately due and payable and exercise other rights and remedies provided for under the Revolving Credit Facility. During the existence of an event of default, interest on the obligations under the Revolving Credit Facility could be increased to 5.0% above the otherwise applicable rate of interest. The Company was in compliance with all the terms and conditions of the Revolving Credit Facility at June 30, 2019 |

Convertible Notes The estimated fair value of the 2014 and 2018 Notes is based on a market approach and represents a Level II valuation. When determining the estimated fair value of our long-term debt, we used a commonly accepted valuation methodology and market-based risk measurements that are indirectly observable, such as credit risk. The following table summarizes the par value, carrying value and the estimated fair value of the 2014 and 2018 Notes at June 30, 2019 and December 31, 2018, respectively (in thousands): June 30, 2019 December 31, 2018 Par Value Carrying Value Fair Value Par Value Carrying Value Fair Value 2014 Notes $ 51,250 $ 49,833 $ 49,559 $ 51,250 $ 49,794 $ 43,665 2018 Notes — — — 149,999 122,264 171,843 Total $ 51,250 $ 49,833 $ 49,559 $ 201,249 $ 172,058 $ 215,508 |

Share-based Payment Arrangement [Abstract] | |
Stock-Based Plans | Stock-Based Plans Our board of directors sets the terms, conditions, and restrictions related to our Employee Stock Purchase Plan (ESPP) and the grant of stock options, restricted stock units (RSU) and performance-based awards under our other equity incentive plans. Our board of directors determines the number of shares subject to award grants and also sets vesting criteria. In general, our RSUs vest on a quarterly basis over a period of four years from the date of grant at a rate of 25% on the first anniversary of the grant date and ratably each quarter over the remaining 12 quarters, subject to the recipient employee’s continued employment. We may grant RSU awards with different vesting terms from time to time. Incentive stock options and non-statutory stock options granted under the 2011 Plan have a term of no more than ten years from the date of grant and an exercise price of at least 100% of the fair market value of the underlying common stock on the date of grant. If a participant owns stock representing more than 10% of the voting power of all classes of our stock on the grant date, an incentive stock option awarded to the participant will have a term of no more than five years from the date of grant and an exercise price of at least 110% of the fair market value of the underlying common stock on the date of grant. Generally, our options vest at a rate of either 25% on the first anniversary of the option grant date and ratably each month over the remaining period of 36 months, or ratably each month over 48 months. We may grant options with different vesting terms from time to time. For performance-based share awards, our board of directors sets the performance objectives and other vesting provisions in determining the number of shares or value of performance units and performance shares that will be paid out. Such payout will be a function of the extent to which performance objectives or other vesting provisions have been achieved. 2011 Equity Incentive Plan In January 2011, our board of directors adopted the 2011 Equity Incentive Plan (2011 Plan) under which incentive stock options, non-statutory stock options, RSUs, stock appreciation rights, performance units, and performance shares may be granted to our employees, directors, and consultants. In April 2019, our board of directors authorized, and in June 2019, our stockholders approved, the amendment and restatement of the 2011 Plan to make various changes, including increasing the number of shares reserved for issuance by approximately 5.0 million shares and extending the term of the 2011 Plan until April 2029. 2009 Equity Incentive Plan and 1999 Stock Option Plan Our 2009 Equity Incentive Plan (2009 Plan) terminated on the date the 2011 Plan was adopted. Options granted and shares issued under the 2009 Plan that were outstanding on the date the 2011 Plan became effective remained subject to the terms of the 2009 Plan. 2017 Inducement Award Plan In January 2017, we adopted the Fluidigm Corporation 2017 Inducement Award Plan (Inducement Plan) and reserved 2 million shares of our common stock for issuance pursuant to equity awards granted under the Inducement Plan. The Inducement Plan provided for the grant of equity-based awards and its terms were substantially similar to the 2011 Plan. In accordance with Rule 5635(c)(4) of the Nasdaq Listing Rules, awards under the Inducement Plan could only be made to individuals not previously our employees or non-employee members of our board of directors (or following such individuals' bona fide period of non-employment), as an inducement material to the individuals' entry into employment with us or in connection with a merger or acquisition, to the extent permitted by Rule 5635(c)(3) of the Nasdaq Listing Rules. In June 2019, concurrently with the increase in shares available for grant under the 2011 Plan, the Inducement Plan was terminated such that no further grants could be made thereunder. Options granted and shares issued under the Inducement Plan that were outstanding upon such termination remain outstanding subject to their terms and the terms of the Inducement Plan. Valuation and Expense Information We use the Black-Scholes option-pricing model to estimate the fair value of stock options granted under our equity incentive plans. We grant stock options at exercise prices not less than the fair value of our common stock at the date of grant. The fair value of RSUs granted to employees is valued using the fair market value of our common stock on the grant date. Activity under the 2011 Plan, the 2009 Plan, the 1999 Plan, and the Inducement Plan is as follows: Restricted Stock Units : Number of Units (in 000s) Weighted-Average Balance as of December 31, 2018 1,812 $ 7.09 RSU granted 662 $ 10.90 RSU released (360) $ 8.66 RSU forfeited (224) $ 8.14 Balance as of June 30, 2019 1,890 $ 8.01 As of June 30, 2019 , the unrecognized compensation costs related to outstanding unvested RSUs under our equity incentive plans were $12.6 million . We expect to recognize these costs over a weighted average period of 3 years. Stock Options : Number of Weighted-Average Weighted- Aggregate Balance as of December 31, 2018 2,385 $ 7.56 7.8 $ 5,991 Options granted 41 $ 13.41 Options exercised (184 ) $ 5.75 $ 1,147 Options forfeited (138 ) $ 6.5 Balance as of June 30, 2019 2,104 $ 7.8 7.3 $ 11,453 Vested as of June 30, 2019 1,159 $ 9.16 6.3 $ 5,556 Expected to vest as of June 30, 2019 945 $ 6.13 8.5 $ 5,897 The grant date fair value of options granted in 2019 was $7.36 . As of June 30, 2019 , the unrecognized compensation costs related to outstanding unvested options under our equity incentive plans were $3.2 million. We expect to recognize these costs over a weighted average period of 2.1 years. Performance-based Awards: Performance Stock Units During the three and six months ended June 30, 2019 , we granted 25,500 and 400,839 performance stock units, respectively, to certain executive officers and senior level employees. The number of performance stock units ultimately earned under these awards is calculated based on the Total Shareholder Return (TSR) of our common stock as compared to the TSR of a defined group of peer companies during the three-year performance period. The percentage of performance stock units that vest will depend on our relative position at the end of the performance period and can range from 0% to 200% of the number of units granted. Under FASB ASC Topic 718, the provisions of the performance stock unit awards related to TSR are considered a market condition, and the effects of that market condition should be reflected in the grant date fair value of the awards. We used a Monte Carlo simulation pricing model to incorporate the market condition effects at our grant date with a weighted-average fair value of $16.90 per unit. Activity under the performance stock units is as follows: Number of Units (in 000s) Weighted-Average Balance as of December 31, 2018 155 $ 10.09 PSU granted 401 $ 16.90 PSU released — $ — PSU forfeited (9 ) $ 10.09 Balance as of June 30, 2019 547 $ 15.09 As of June 30, 2019 , the unrecognized compensation costs related to these awards were $6.8 million. We expect to recognize these costs over a weighted average period of 2.5 years. 2017 Employee Stock Purchase Plan Our ESPP offers U.S. and some non-U.S. employees the right to purchase shares of our common stock. Prior to June 2019, our ESPP had a six-month offering period, with a new period commencing on the first trading day on or after May 31 and November 30 of each year. Employees were eligible to participate through payroll deductions of up to 10% of their compensation. The purchase price at which shares were sold under the ESPP was 85% of the lower of the fair market value of a share of our common stock on the first day of the offering period or the last day of the offering period. Effective in June 2019, our ESPP was amended to offer a twelve-month offering period with two six-month purchase periods beginning on each of May 31 and November 30. Under the updated plan, the purchase price at which shares are sold for the first purchase period is 85% of the lower of the fair market value of a share of our common stock on the first day of the offering period or the last day of the first purchase period. For the second purchase period, the purchase price at which shares are sold is 85% of the lowest of the fair value of the common stock on the first day of the offering period, the last day of the offering period or the fair value of the common stock at the beginning of the second purchase period. Employees are eligible under the amended plan to participate through payroll deductions of up to 15% of their compensation. Employees may not purchase more than $25 thousand of stock for any calendar year. Share-based Compensation We recognized share-based compensation expense as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Options and Restricted Stock Units $ 2,848 $ 1,888 $ 4,993 $ 3,514 Employee Stock Purchase Plan 144 119 270 240 Total Share-based Compensation $ 2,992 $ 2,007 $ 5,263 $ 3,754 |

Income Tax Disclosure [Abstract] | |
Income Taxes | Income Taxes The Company’s quarterly provision for income taxes is based on an estimated effective annual income tax rate. The Company’s quarterly provision for income taxes also includes the tax impact of certain unusual or infrequently occurring items, if any, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur. The Company recorded a tax benefit of $1.1 million for both the three and six months ended June 30, 2019 . We recorded a tax benefit of $0.2 million and $1.4 million for the three and six months ended June 30, 2018 . The benefit for all periods was primarily attributable to the tax benefit from the amortization of our acquisition-related deferred tax liability, partially offset by a provision from our foreign operations. The Company’s tax benefit for income taxes for the periods presented differs from the 21% U.S. Federal statutory rate for the three and six months ended June 30, 2019 and 2018 , respectively, primarily due to maintaining a valuation allowance for deferred tax assets, which primarily consist of net operating loss carryforwards. Tax positions taken by the Company are subject to audits by multiple tax jurisdictions. The Company believes that it has provided adequate reserves for its uncertain tax positions for all tax years still open for assessment. The Company also believes that it does not have any tax position that will significantly increase or decrease within the next year. For the six months ended June 30, 2019, the Company did not recognize any material interest or penalties related to uncertain tax positions. Recording deferred tax assets is appropriate when realization of these assets is more likely than not. Assessing the realizability of deferred tax assets is dependent upon several factors including historical financial results. The deferred tax assets have been offset by valuation allowances. In the future we may release valuation allowances and recognize deferred tax assets in certain of our foreign subsidiaries depending on the achievement of future profitability in the relevant jurisdictions. Any release of valuation allowances could have the effect of decreasing the income tax provision in the period the valuation allowance is released. We continue to monitor the likelihood that we will be able to recover our deferred tax assets, including those for which a valuation allowance is recorded. There can be no assurance that we will generate profits in the future periods enabling us to fully realize our deferred tax assets. The timing of recording a valuation allowance or the reversal of such valuation allowance is subject to objective and subjective factors that cannot be readily predicted in advance. |

Segment Reporting [Abstract] | |
Information about Geographic Areas | Information about Geographic Areas We operate in one reporting segment that develops, manufacturers and commercializes tools for life sciences research. Our chief executive officer manages our operations and evaluates our financial performance on a consolidated basis. For purposes of allocating resources and evaluating regional financial performance, our chief executive officer reviews separate sales information for the different regions of the world. Our general and administrative expenses and our research and development expenses are not allocated to any specific region. Most of our principal operations, other than manufacturing, and our decision-making functions are located at our corporate headquarters in the United States. A summary table of our total revenue by geographic areas of our customers and by product and service for the three and six months ended June 30, 2019 and 2018 is included in Note 3 to the condensed consolidated financial statements of this quarterly report on Form 10-Q. Sales to customers in the United States represented $9.9 million or 35% , and $22.4 million or 38% of total revenues for the three and six months ended June 30, 2019 , respectively. Sales to customers in the United States represented $12.0 million or 46% and $22.2 million or 43% of total revenues for the three and six months ended June 30, 2018 , respectively. Sales to customers in China represented $4.0 million or 14% and $7.5 million or 13% of total revenues for the three and six months ended June 30, 2019 , respectively. Sales to customers in China represented $2.3 million or 9% and $5.6 million or 11% of total revenues for the three and six months ended June 30, 2018 , respectively. Except for China, no other foreign country or jurisdiction had sales in excess of 10% of our total revenue during the three and six months ended June 30, 2019 and 2018 . No individual customer represented more than 10% of our total revenues for the three and six months ended June 30, 2019 , and 2018 |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Indemnification From time to time, we have entered into indemnification provisions under certain of our agreements in the ordinary course of business, typically with business partners, customers, and suppliers. Pursuant to these agreements, we may indemnify, hold harmless, and agree to reimburse the indemnified parties on a case-by-case basis for losses suffered or incurred by the indemnified parties in connection with any patent or other intellectual property infringement claim by any third party with respect to our products. The term of these indemnification provisions is generally perpetual from the time of the execution of the agreement. The maximum potential amount of future payments we could be required to make under these indemnification provisions is typically not limited to a specific amount. In addition, we have entered into indemnification agreements with our officers, directors, and certain other employees. With certain exceptions, these agreements provide for indemnification for related expenses including, among others, attorneys’ fees, judgments, fines and settlement amounts incurred by any of these individuals in any action or proceeding.

Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (U.S. GAAP) and include the accounts of our wholly owned subsidiaries. As of June 30, 2019 , we had wholly owned subsidiaries in Singapore, Canada, the Netherlands, Japan, France, the United Kingdom, China, and Germany. All subsidiaries, except for Singapore, use their local currency as their functional currency. The Singapore subsidiary uses the U.S. dollar as its functional currency. All intercompany transactions and balances have been eliminated in consolidation. Certain prior period amounts in the condensed consolidated statements of cash flows were reclassified to conform with the current period presentation. These reclassifications were immaterial and did not affect prior period total assets, total liabilities, stockholders' equity, total revenue, total costs and expenses, loss from operations or net loss. |
Net Loss per Share | Net Loss per Share Our basic and diluted net loss per share is calculated by dividing net loss by the weighted-average number of shares of common stock outstanding for the period. Restricted stock units, options to purchase common stock, and shares associated with the potential conversion of our convertible notes are considered to be potentially dilutive common shares but have been excluded from the calculation of diluted net loss per share as their effect is anti-dilutive for all periods presented. |
Revenue Recognition | Revenue Recognition We generate revenue primarily from the sale of our products and services. Product revenue is derived from the sale of instruments and consumables, including IFCs, assays and reagents. Service revenue is derived from the sale of instrument service contracts, repairs, installation, training and other specialized product support services. Revenue is reported net of any sales, use and value-added taxes we collect from customers as required by government authorities. We recognize revenue based on the amount of consideration we expect to receive in exchange for the goods and services we transfer to the customer. Our commercial arrangements typically include multiple distinct products and services, and we allocate revenue to these performance obligations based on their relative standalone selling prices. Standalone selling prices (SSP) are generally determined using observable data from recent transactions. In cases where sufficient data is not available, we estimate a product’s SSP using a cost plus a margin approach or by applying a discount to the product’s list price. Product Revenue We recognize product revenue at the point in time when control of the goods passes to the customer and we have an enforceable right to payment. This generally occurs either when the product is shipped from one of our facilities or when it arrives at the customer’s facility, based on the contractual terms. Customers generally do not have a unilateral right to return products after delivery. Invoices are generally issued at shipment and generally become due in 30 to 60 days. We sometimes perform shipping and handling activities after control of the product passes to the customer. We have made an accounting policy election to account for these activities as product fulfillment activities rather than as separate performance obligations. Service Revenue We recognize revenue from repairs, installation, training and other specialized product support services at the point in time the work is completed. Installation and training services are generally billed in advance of service. Repairs and other services are generally billed at the point the work is completed. Revenue associated with instrument service contracts is recognized on a straight-line basis over the life of the agreement, which is generally one to three years. We believe this time-elapsed approach is appropriate for service contracts because we provide services on demand throughout the term of the agreement. Invoices are generally issued in advance of service on a monthly, quarterly, annual or multi-year basis. Payments made in advance of service are reported on our consolidated balance sheet as deferred revenue. Contract Costs Incremental sales commission costs incurred to obtain instrument service contracts are capitalized and amortized to selling, general and administrative expense over the life of the contract, which is generally one to three years. As a practical expedient, we expense sales commissions associated with product support services that are delivered in less than one year as they are incurred. Sales commissions associated with the sale of products are expensed as they are incurred. Product Warranties We generally provide a one-year warranty on our instruments. We accrue for estimated warranty obligations at the time of product shipment. We periodically review our warranty liability and record adjustments based on the terms of warranties provided to customers, and historical and anticipated warranty claim experience. This expense is recorded as a component of cost of product revenue in the condensed consolidated statements of operations. Significant Judgments Applying the revenue recognition practices discussed above often requires significant judgment. Judgment is required when identifying performance obligations, estimating SSP and allocating purchasing consideration in multi-element arrangements and estimating the future amount of our warranty obligations. Moreover, significant judgment is required when interpreting commercial terms and determining when control of goods and services passes to the customer. Any material changes created by errors in judgment could have a material effect on our operating results and overall financial condition. |
Goodwill, Intangible Assets, and Other Long-lived Assets | Goodwill, Intangible Assets, and Other Long-lived Assets Goodwill, which has an indefinite useful life, represents the excess of cost over fair value of net assets acquired. Our intangible assets include developed technology, patents and licenses. The cost of identifiable intangible assets with finite lives is generally amortized on a straight-line basis over the assets’ respective estimated useful lives. Goodwill and intangible assets with indefinite lives are not subject to amortization but are tested for impairment on an annual basis during the fourth quarter or whenever events or changes in circumstances indicate the carrying amount of these assets may not be recoverable. We first conduct an assessment of qualitative factors to determine whether it is more likely than not that the fair value of our reporting unit is less than its carrying amount. If we determine that it is more likely than not that the fair value of our reporting unit is less than its carrying amount, we then conduct a two-step test for impairment of goodwill. In the first step, we compare the fair value of our reporting unit to its carrying value. If the fair value of our reporting unit exceeds its carrying value, goodwill is not considered impaired and no further analysis is required. If the carrying value of the reporting unit exceeds its fair value, then the second step of the impairment test must be performed in order to determine the implied fair value of the goodwill. If the carrying value of the goodwill exceeds its implied fair value, then an impairment loss equal to the difference would be recorded. We evaluate our long-lived assets, including finite-lived intangibles, for indicators of possible impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. If any indicator of impairment exists, we assess the recoverability of the affected long-lived assets by determining whether the carrying value of the asset can be recovered through undiscounted future operating cash flows. If impairment is indicated, we estimate the asset’s fair value using future discounted cash flows associated with the use of the asset and adjust the carrying value of the asset accordingly. We did not recognize any impairment of long-lived assets for any of the periods presented herein. |
Convertible Notes | Convertible Notes In February 2014, we closed an underwritten public offering of $201.3 million aggregate principal amount of our 2.75% Senior Convertible Notes due 2034 (2014 Notes). In March 2018, we entered into separate privately negotiated transactions with certain holders of our 2014 Notes to exchange $150.0 million in aggregate principal amount of the 2014 Notes for our new 2.75% Exchange Convertible Senior Notes due 2034 (2018 Notes). Following the exchange, approximately $51.3 million in aggregate principal amount of the 2014 Notes was outstanding in addition to $150.0 million |
Recent Accounting Changes and Accounting Pronouncements | Recent Accounting Changes and Accounting Pronouncements Adoption of New Accounting Guidance In February 2016, the FASB established Topic 842, Leases, by issuing Accounting Standards Update (ASU) No. 2016-02, which requires lessees to recognize operating leases on the balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use (ROU) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases are classified as finance or operating; the classification will impact the expense recognition in the income statement. Modified Retrospective Transition approach is required, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. We adopted the new standard on January 1, 2019 and used the effective date of the standard as our date of initial application. Consequently, previously presented financial information has not been updated, and the disclosures required under the new standard have not been provided for dates and periods before January 1, 2019. For dates and periods prior to January 1, 2019, the original disclosures under ASC 840 are disclosed. The new standard provides several optional practical expedients in transition. We elected the ‘package of practical expedients,’ which permits us to not reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. We did not elect the use-of-hindsight or the practical expedient pertaining to land easements; the latter not being applicable to us. On adoption, we recognized $9.2 million of lease liabilities, based on the present value of the current minimum lease payments over the lease term, discounted using our collateralized incremental borrowing rate, with corresponding ROU assets of $ 7.4 million . The difference between the initial lease liability and ROU asset is attributable to deferred rent. There was no impact to retained earnings from the adoption of ASC 842. The new standard also provides certain accounting elections for an entity’s ongoing accounting. We have elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, we will not recognize ROU assets or lease liabilities for leases with an initial lease term of one year or less. We have also elected to not separate lease and nonlease components for our building leases. The nonlease components are generally variable in nature and are expected to comprise most of our variable lease costs. Variable costs are expensed as incurred. We have taken a portfolio approach for our vehicle leases by country. Recent Accounting Pronouncements In August 2018, the FASB issued ASU 2018-15 Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) which establishes new guidance on the accounting for costs incurred to implement a cloud computing arrangement that is considered a service arrangement. The new guidance requires the capitalization of such costs, aligning it with the accounting for costs associated with developing or obtaining internal-use software. The new guidance is effective for fiscal years beginning after December 15, 2019. We are currently evaluating the impact of adoption on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The ASU eliminates the requirement for an entity to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, an entity performs its annual, or interim, goodwill impairment testing by comparing the fair value of a reporting unit with its carrying amount and recording an impairment charge for the amount by which the carrying amount exceeds the fair value. The ASU will be effective for annual and interim goodwill impairment testing performed for our fiscal year beginning January 1, 2020, with early adoption permitted. We are currently evaluating the effect that the updated standard will have on our consolidated financial statements. The FASB issued two ASUs related to financial instruments – credit losses. The ASUs issued were: (1) in June 2016, ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, and (2) in November 2018, ASU 2018-19 Codification Improvements to Topic 326, Financial Instruments—Credit Losses. ASU 2016-13 is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. ASU 2018-19 clarifies that receivables arising from operating leases are not within the scope of the credit losses standard, but rather, should be accounted for in accordance with the leasing standard. These ASUs are effective for fiscal years beginning after December 15, 2019, and interim periods within those years, with early adoption permitted. We are evaluating the effect that ASU 2016‑13 and ASU 2018-19 will have on our consolidated financial statements and related disclosures. |
