Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt Paycheck Protection Program On April 17, 2020, the Company received the PPP Loan proceeds of approximately $1.8 million pursuant to the Paycheck Protection Program under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) administered by the U.S. Small Business Administration (the “SBA”). The PPP Loan accrued interest at a rate of 1% per annum and was subject to the standard terms and conditions applicable to loans administered by the SBA under the CARES Act. In February 2021, the Company applied for forgiveness of the PPP Loan, and in March 2021, the PPP Loan, including all accrued interest, was forgiven in full. A gain on forgiveness of Paycheck Protection Program loan of $1.8 million was recognized during the year ended December 31, 2021. Innovatus Loan and Security Agreement In March 2019, the Company entered into a Loan and Security Agreement (the “LSA”) by and among Innovatus Life Sciences Lending Fund I, LP, a Delaware limited partnership (“Innovatus”), as collateral agent and the lenders listed on Schedule 1.1 thereto, including East West Bank. The LSA provided a first term loan of $17.5 million, a second term loan of $2.5 million and a third term loan of $5.0 million (collectively, the “Term Loans”) if the Company satisfied certain funding conditions. Interest on the Term Loans was due on the first of each month at a rate of 10.25% per annum in cash or a discounted rate of 7.25% in cash with 3.0% of the 10.25% per annum rate added to the principal of the loan and subject to accruing interest through the end of the interest only payment period, which was scheduled to end March 1, 2022. At inception, the Company elected to pay interest in cash at a rate of 7.25% per annum and have 3.0% per annum of the interest added back to the outstanding principal. As of May 14, 2021 (the effective date of the loan payoff), the effective interest rate, including debt issuance costs, for the Term Loans was 16.7%. The LSA provided for prepayment fees of 3.0% of the outstanding balance of the loan if the loan was repaid on or prior to March 14, 2020, 2.0% of the amount prepaid if the prepayment occurs after March 14, 2020 but prior to March 14, 2021, 1% of the amount prepaid after March 14, 2021 but prior to March 14, 2022 and 0% of the amount prepaid if the prepayment occurs thereafter. In addition, upon the final repayment of the total amounts borrowed, the Company was required to pay an end of term fee of $0.8 million. This end of term fee was being recognized as interest expense over the term of the LSA. As of December 31, 2021, the outstanding term loan with Innovatus was paid in full, including all accrued interest, the end of term fee, and a prepayment fee for a total of $17.0 million. The Company recorded a loss on debt extinguishment of $2.1 million. The LSA also provided for a revolving line of credit in an amount not to exceed $5.0 million (the “Revolver”), which was terminated effectively upon payment in full of the above term loan. The LSA was collateralized by substantially all of the Company’s assets, including its intellectual property. The LSA required the Company to comply with various affirmative and negative covenants, including: (1) a liquidity covenant requiring the Company to maintain a minimum cash balance at all times in a collateral account and (2) a revenue covenant requiring the Company to meet certain minimum revenue targets measured at the end of each calendar quarter. The LSA also included certain standard events of default, and a provision that Innovatus could declare an event of default upon the occurrence of any event that it interprets as having a material adverse impact to the Company's business, operations, or condition, a material impairment on the Company's ability to pay the secured obligations under the LSA, or upon a material adverse effect on the collateral under the agreement, thereby requiring the Company to repay the loans immediately, together with a prepayment fee and other applicable fees. In March 2019, in connection with the receipt of $20.0 million in proceeds from the Term Loans, the Company issued to Innovatus a warrant to purchase up to 0.2 million shares of its common stock at an exercise price of $4.63 per share, which has a term of 10 years. These warrants were equity classified and their respective fair value was recorded as a discount to the debt. The warrants were exercised during the year end December 31, 2021. In June 2019, the LSA was amended to among other things: (i) extend the deadline for the Company to maintain its domestic depository and operating accounts with the Bank, subject to a control agreement in favor of Innovatus, to July 31, 2019 and (ii) permit the Company to incur credit card indebtedness in an amount not to exceed $0.2 million. As of September 30, 2019, the Company did not achieve the revenue covenant under the Innovatus LSA. As a result, in October 2019, the Company obtained a waiver letter from Innovatus. Pursuant to the waiver letter, Innovatus agreed to allow the Company to cure its noncompliance with the revenue covenant as of September 30, 2019 so long as the Company (i) raised at least $10 million in gross proceeds from the sale of its securities in an underwritten public offering by October 31, 2019 and (ii) amended the warrant to purchase stock, issued by the Company to Innovatus in March 2019 to decrease the exercise price of the warrant from $4.63 per share to $0.48 per share. Also pursuant to the waiver letter, as consideration for the prospective breach of a liquidity covenant, the Company agreed to issue to Innovatus $0.6 million shares of the Company's common stock. As a result of the amendment and shares issued, the Company recognized $0.6 million as a debt discount, which was being amortized as interest expense over the remaining term of the LSA. As of December 31, 2019, the Company did not achieve certain financial covenants under the Innovatus LSA. As a result, in March 2020, the Company and Innovatus entered into an amendment to the Innovatus LSA (the “Second Amendment”) to, among other things: (i) waive the events of default from not achieving the specific financial covenants for the December 31, 2019 measurement date, (ii) require an immediate partial repayment of $2.1 million, (iii) require an additional partial repayment of $2.9 million on the earlier of completion of an Equity Event (as defined in the Second Amendment), or April 30, 2020, (iv) modify the liquidity covenant, such that the Company’s minimum cash balance shall vary based on outstanding borrowing capacity under the Revolver (provided, however, that the Company shall maintain a minimum cash balance of $2 million at any given time), (v) reduce the dollar amount of certain minimum revenue covenants measured as of the end of each calendar quarter (each, a “Revenue Covenant”) and (vi) modify the terms of certain events of default. For example, the Second Amendment provides for a cure period in connection with the breach of certain minimum revenue financial covenants, as long as the Company submits an updated management plan and financial projections, which are subject to Innovatus approval, and completes a Qualified Financing Event (as defined in the Second Amendment) within 45 days of such breach. In connection with the Second Amendment, the Company was obligated to pay Innovatus a waiver fee in the amount of $0.2 million and a prepayment fee of $0.1 million, payable in cash or in shares of the Company’s common stock at the Company's election, no later than following completion of the Equity Event, as defined in the Second Amendment. The Company completed a follow-on public offering in April 2020 that constituted an Equity Event under the Second Amendment. A portion of the proceeds from the follow-on offering were used to pay-down $2.9 million of principal balance outstanding under the Term Loans in accordance with the Second Amendment. In addition, the Company issued 0.9 million shares of its common stock to Innovatus to satisfy the $0.2 million waiver fee and the $0.1 million prepayment fee due under the Second Amendment. As a result of the amendment and shares issued, the Company recognized $0.3 million as a debt discount, which was being amortized as interest expense over the remaining term of the LSA. Also pursuant to the Second Amendment, the Company subsequently registered such shares for resale on a registration statement on Form S-3 (the “Registration Statement”) filed with the Securities and Exchange Commission on June 22, 2020 and declared effective on July 7, 2020. The Company has not and will not receive any of the proceeds from the offering described in the Registration Statement. In connection with the Merger, the Company and Lineagen entered into a Third Amendment (the “Third Amendment”) to the Innovatus LSA. Among other things, the Third Amendment adds Lineagen as a “Borrower” under the Innovatus LSA and updates certain financial covenants in light of Lineagen becoming a wholly owned subsidiary of the Company. The Innovatus LSA was paid in full and terminated in 2021.
