Substantial Doubt about Going Concern [Text Block] | 2. Going Concern The Company has incurred historical losses from operations and expects to continue to incur operating losses in the near future. The Company may need to raise additional capital to grow its business, fund operating expenses and make interest payments. The Company’s ability to fund its liquidity needs is subject to various risks, many of which are beyond its control. The Company may seek additional funding through debt borrowings, sales of debt or equity securities or strategic partnerships. The Company cannot guarantee that such funding will be available on a timely basis, in needed quantities or on terms favorable to the Company, if at all. These factors and other indicators raise substantial doubt about the Company’s ability to continue as a going concern within one year from the filing date of this report. The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result should the Company be unable to continue as a going concern. |

Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block] | 3. Summary of Significant Accounting Polices There have been no material changes in the Company’s significant accounting policies to those disclosed in the 2022 Annual Report. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such Securities and Exchange Commission (“SEC”) rules and regulations and accounting principles applicable for interim periods. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Events subsequent to the balance sheet date have been evaluated for inclusion in the accompanying condensed consolidated financial statements through the date of issuance. Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the Company’s fiscal year ending December 31, 2023. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in ThermoGenesis Holdings’ Annual Report on Form 10-K for the year ended December 31, 2022. Principles of Consolidation The consolidated financial statements include the accounts of ThermoGenesis Holdings and its wholly-owned subsidiaries, ThermoGenesis Corp. and TotipotentRX Cell Therapy, Pvt. Ltd and ThermoGenesis Corp’s majority-owned subsidiary, CARTXpress Bio. All significant intercompany accounts and transactions have been eliminated upon consolidation. The 20% ownership interest of CARTXpress Bio that is not owned by ThermoGenesis Holdings is accounted for as a non-controlling interest as the Company has an 80% ownership interest in CARTXpress Bio. Earnings or losses attributable to other stockholders of a consolidated affiliated company are classified separately as "non-controlling interest" in the Company's consolidated statements of operations. Net loss attributable to non-controlling interests reflects only its share of the after-tax earnings or losses of an affiliated company. The Company's condensed consolidated balance sheets reflect non-controlling interests within the equity section. Recently Adopted Accounting Standards On January 1, 2022, we adopted Accounting Standards Update (“ASU”) 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, In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses ( Topic 326 ). |

Related Party Transactions Disclosure [Text Block] | 4. Related Party Transactions Convertible Promissory Note and Revolving Credit Agreement In March 2017, ThermoGenesis Holdings entered into a Credit Agreement with Boyalife Group (USA), Inc. (the “Lender”), which is owned and controlled by the Company’s Chief Executive Officer and Chairman of our Board of Directors. The Credit Agreement, as amended, grants the Company the right to borrow up to $10,000,000 (the “Loan”) at any time prior to the maturity date. On March 6, 2023, the Company entered into an Amendment No. 2 (the “Amendment to the Note”) to its Second Amended and Restated Convertible Promissory Note with Boyalife Group Inc. (the “Note”), and an Amendment No. 3 to its First Amended and Restated Revolving Credit Agreement with Boyalife Group Inc. The Amendment to the Note amended and extended the maturity date of the Note from March 6, 2023 to December 31, 2023 (the “Maturity Date”), and added to the principal balance of the Note all accrued and unpaid interest at the time of the extension, resulting in an outstanding principal balance of $7,278,000. The Company performed a debt extinguishment vs. modification analysis on the Amendment to the Note and determined that the amendment would be considered an extinguishment, due to an increase of more than 10% to the value of the embedded conversion option. However, no gain or loss was recorded in the condensed consolidated statements of operations and comprehensive loss for the quarter ended March 31, 2023 as it was determined that the fair value of the Amendment to the Note and accrued interest was $7,278,000 both before and after the extension. The Credit Agreement and the Note, as amended provide that the principal and all accrued and unpaid interest under the Loan will be due and payable on the Maturity Date, with payments of interest-only due on the last day of each calendar year. The Loan bears interest at 22% per annum, simple interest. The Company has five business days after the Lender demands payment to pay the interest due before the Loan is considered in default. The Loan can be prepaid in whole or in part by the Company at any time without penalty. The following summarizes the Note: Maturity Date Stated Interest Rate Conversion Price Face Value Debt Discount Carrying Value March 31, 2023 12/31/23 22 % $ 2.65 $ 7,278,000 $ (779,000 ) $ 6,499,000 December 31, 2022 12/31/23 22 % $ 6.30 $ 7,000,000 $ (1,223,000 ) $ 5,777,000 The Note includes a down-round anti-dilution provision that lowers its conversion price if the Company sells shares of common stock or issues convertible debt at a lower price per share. In 2023, the down-round provision was triggered two times, as noted below: In January 2023, when the conversion price of the Note was at $6.30 per share, the Company amended a previously outstanding convertible note, resulting in a triggering event lowering the conversion price of the Note to $2.87. The Company determined that it created an incremental value of $2,350,000 which was treated as a discount to the carrying amount of the Note and amortized over its remaining term. In March 2023, the Company sold shares of common stock and warrants at $2.65 per share, resulting in a down round triggering event lowering the conversion price of the Note to that value. The triggering event created an incremental value of $810,000 which was treated as a discount to the carrying amount of the Note and will be amortized over its remaining term. A Black-Scholes pricing model was utilized to determine the change in the before and after incremental value of the conversion option at each triggering event, with the following inputs: January 2023 March 2023 Conversion price before $ 6.30 $ 2.87 Conversion price after $ 2.87 $ 2.65 Term (years) 0.09 0.78 Volatility 167 % 168.9 % Dividend rate 0 % 0 % Risk free rate 4.46 % 4.20 % The Company amortized $3,604,000 and $213,000 of debt discount related to triggering events to interest expense for the three months ended March 31, 2023 and 2022, respectively. In addition to the amortization, the Company also recorded interest expense of $389,000 and $550,000 for the three months ended March 31, 2023 and 2022 respectively. The interest payable balance as of March 31, 2023 and December 31, 2022 was $111,000 and $1,492,000, respectively.

Debt Disclosure [Text Block] | 6. Convertible Promissory Note July 2019 Note On July 23, 2019, the Company entered into a private placement with Orbrex (USA) Co. Limited (“Orbrex”), pursuant to which the Company issued and sold to Orbrex an unsecured convertible promissory note in the original principal amount of $1,000,000 (the “July 2019 Note”). The July 2019 Note bears interest at a rate of twenty-four percent (24%) per annum and is payable quarterly in arrears. On January 31, 2023, the Company entered into Amendment No. 3 to the July 2019 Note. The amendment extended the maturity date from January 31, 2023 to July 31, 2023 and changed the fixed conversion price to $2.87 per share. The Company performed a debt extinguishment vs. modification analysis on the amendment to the July 2019 Note and determined that the extension would be considered an extinguishment, due to an increase of more than 10% to the value of the embedded conversion option. The Company determined that the fair value of the July 2019 Note after the amendment was $1,239,000 representing a $239,000 increase in its fair value. The increase will be recorded as a premium to the July 2019 Note and amortized over the remaining term. During the three months ended March 31, 2023, the holder of the July 2019 Note converted $603,000 of the Note for 215,000 shares. The current outstanding balance of the Note is $397,000. The following summarizes the July 2019 Note: Maturity Date Stated Interest Rate Conversion Price Face Debt Debt Carrying Value March 31, 2023 7/31/2023 24 % $ 2.65 $ 397,000 $ (40,000 ) $ 66,000 $ 423,000 December 31, 2022 7/31/2023 24 % $ 6.30 $ 1,000,000 $ (38,000 ) $ - $ 962,000 The Note includes a down-round anti-dilution provision that lowers its conversion price if the Company sells shares of common stock or issues convertible debt at a lower price per share. In 2023, the anti-dilution provision was triggered, as noted below: In March 2023, the Company sold shares of common stock at $2.65 per share, resulting in a down round triggering event lowering the conversion price of the Note to that value. The triggering event created an incremental value of $43,000 which was treated as a discount to the carrying amount of the July 2019 Note and will be amortized over its remaining term. A Black-Scholes pricing model was utilized to determine the change in the before and after incremental value of the conversion option at each triggering event, with the following inputs: March 2023 Conversion price before $ 2.87 Conversion price after $ 2.65 Term (years) 0.36 Volatility 182 % Dividend rate 0 % Risk free rate 4.20 % The Company recorded amortization expense related to triggering events for the July 2019 Note of $41,000 for the three months ended March 31, 2023. Additionally, amortization expense related to the debt premium for the July 2019 Note was $174,000 for the three months ended March 31, 2023. Interest expense related to the July 2019 Note was $42,000 and $60,000 for the three months ended March 31, 2023 and 2022, respectively. |

Share-Based Payment Arrangement [Text Block] | 7. Stockholders Equity Common Stock On March 15, 2023, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with an accredited investor (the “Investor”) pursuant to which the Company agreed to issue and sell to the Investor in a private placement (the “Offering”) (i) 125,000 shares of its common stock, $0.001 par value (the “Common Shares”), (ii) 946,429 pre-funded warrants to purchase Common Shares at a purchase price of $2.80, and (iii) warrants to purchase up to an aggregate 1,071,429 Common Shares were issued (the “Underlying Shares”). The warrants have an exercise price of $2.65 per share and are exercisable immediately upon issuance and expire five and one-half years following the issuance for a total net proceeds of approximately $2.6 million, excluding legal and transaction fees of $360,000. The Offering closed on March 20, 2023. In connection with the Offering, the Company entered into a Warrant Amendment Agreement (the "Warrant Amendment Agreement”), dated March 15, 2023, with the Investor, whereby the Company agreed to amend existing warrants, held by the Investor, to purchase up to an aggregate of 158,731 shares of common stock under the Warrant Amendment Agreement that were previously issued in October 2022. These warrants had an exercise price of $6.30 per share and pursuant to the Warrant Amendment Agreement, have been amended to reduce the exercise price to $2.65 per share effective upon the closing of the Offering. During the quarter ended March 31, 2023, 158,731 common warrants were exercised. The Company received approximately $421,000 from the exercises of the warrants. The warrant repricing resulted in an immediate and incremental increase of approximately $50,000 in the estimated fair value of the common warrants issued in the Company’s October 2022 public offering. The common warrants were valued on the date of the warrant repricing using the Black-Scholes option pricing model based on the following assumptions: March 2023 Conversion price before $ 6.30 Conversion price after $ 2.65 Term (years) 4.9 Volatility 123 % Dividend rate 0 % Risk free rate 4.20 % On February 3, 2022, the Company entered into Amendment No. 2 to the At the Market Offering Agreement (the “Offering Agreement”) with H.C. Wainwright & Co., LLC to further increase the maximum aggregate offering price of shares of Common Stock that may be offered and sold from time to time under the Offering Agreement from $15,280,000 to $19,555,000, which enables the Company to sell an additional $4,275,000 of shares after taking into account prior sales under the Offering Agreement (the “Additional Shares”). In March 2022, the total offering price was updated to $18,573,000 based on the shares that were currently available on Company’s existing Form S-3. The terms and conditions of the Offering Agreement otherwise remain unchanged. For the quarter ended March 31, 2022, the Company sold a total of 20,407 shares of common stock under the Offering Agreement for aggregate gross proceeds of $681,000 at an average selling price of $33.30 per share, resulting in net proceeds of approximately $594,000 after deducting commissions and other transaction costs of approximately $87,000. Net Loss Per Share Net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding plus the pre-funded warrants. For the purpose of calculating basic net loss per share, the additional shares of common stock that are issuable upon exercise of the pre-funded warrants have been included since the shares are issuable for a negligible consideration and have no vesting or other contingencies associated with them. There were 946,429 pre-funded warrants included in the quarter ended March 31, 2023 calculation. The calculation of the basic and diluted earnings per share is the same for all periods presented, as the effect of the potential common stock equivalents noted below is anti-dilutive due to the Company’s net loss position for all periods presented. Anti-dilutive securities consisted of the following at March 31: 2023 2022 Common stock equivalents of convertible promissory notes and accrued interest 2,946,525 157,139 Warrants – other 1,253,387 14,518 Stock options 6,400 8,147 Total 4,206,312 179,804 Warrants A summary of warrant activity for the three months ended March 31, 2023 is as follows: Number of Shares Weighted-Average Exercise Price Per Share Weighted- Average Remaining Contract Term Balance at December 31, 2022 340,689 $ 19.40 1.90 Warrants granted 1,071,429 Pre-funded warrants granted 946,429 Warrants exercised (158,731 ) Exercisable and Outstanding at March 31, 2023 2,199,816 $ 3.84 2.56 |
