Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation and Use of Estimates The accompanying unaudited interim condensed balance sheets as of June 30, 2025, condensed statements of operations and stockholders' equity for the three and six months ended June 30, 2025 and 2024, cash flows for the six months ended June 30, 2025 and 2024 and the related footnote disclosures are unaudited and have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (SEC), and with accounting principles generally accepted in the United States (GAAP) applicable to interim financial statements. These unaudited condensed financial statements and related footnote disclosures should be read in conjunction with the Company’s audited financial statements for the fiscal year ended December 31, 2024, included in its Annual Report on Form 10-K filed with the SEC on March 11, 2025 (the 2024 Annual Report). In management's opinion, the unaudited interim condensed financial statements have been prepared on the same basis as the audited financial statements included in the 2024 Annual Report and include all normal adjustments, necessary for the fair presentation of the Company's financial position as of June 30, 2025 and its results of operations for the periods presented. The results for the three and six months ended June 30, 2025 are not necessarily indicative of the results expected for the full fiscal year or any other interim period. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. Certain reclassifications have been made to prior period amounts to conform to the current presentation. The preparation of the accompanying unaudited condensed financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the condensed financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could materially differ from those estimates. Significant estimates and assumptions made in the accompanying unaudited condensed financial statements include, but are not limited to revenue recognition, the fair value of the warrant liability, the estimated incremental borrowing rate for the determination of the Company's operating lease right-of-use (ROU) assets, and the recoverability of its long-lived assets and net deferred tax assets (and related valuation allowance). The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could materially differ from those estimates. Concentration of Credit Risk and Other Risk and Uncertainties Financial instruments that potentially subject the Company to credit risk consist principally of cash, cash equivalents and accounts receivable. Substantially all the Company's cash and cash equivalents are held at one financial institution that management believes is of high credit quality. Such deposits may, at times, exceed federally insured limits. The Company has not experienced any losses on its cash or cash equivalents. Significant payors and customers are those which represent more than 10% of the Company's total revenue or accounts receivable balance at each respective balance sheet date. For each significant payor and customer, revenue as a percentage of total revenue and accounts receivable as a percentage of total accounts receivable are as follows:
|  | Revenue
|  | Three Months Ended June 30, |  | Six Months Ended June 30,
|  | 2025 |  | 2024 |  | 2025 |  | 2024
Customer A |  | 23 | % |  | 23 | % |  | 23 | % |  | 25 | %
Customer B |  | 16 | % |  | 25 | % |  | 17 | % |  | 21 | %
Customer C |  | * |  | 11 | % |  | 10 | % |  | *
Customer D |  | 10 | % |  | * |  | * |  | *
|  | Accounts Receivable, Net
|  | June 30, 2025 |  | December 31, 2024
Customer A |  | 14 | % |  | 13 | %
Customer B |  | 22 | % |  | 25 | %
* |  | Less than 10%.
For the three months ended June 30, 2025 and 2024, approximately 91% and 90%, respectively, of the Company's revenue was related to the AVISE® CTD test. Revenue related to AVISE® CTD test for the six months ended June 30, 2025 and 2024 was approximately 91% and 90%, respectively. The Company is dependent on key suppliers for certain laboratory materials, consisting primarily of reagents and biomarkers used in our diagnostic tests. For the three months ended June 30, 2025 and 2024 approximately 87% and 99%, respectively, of the Company's diagnostic testing supplies were purchased from two suppliers. For the six months ended June 30, 2025 and 2024, approximately 92% and 97%, respectively, of the Company's diagnostic testing supplies were purchased from three suppliers. An interruption in the supply of these materials would impact the Company's ability to perform testing services. Disaggregation of Revenue The following table includes the Company's revenues as disaggregated by payor and customer category (in thousands):

(1)Includes hospitals, other laboratories, etc. (2)Includes patient self-pay. Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments purchased with a remaining maturity date of three months or less upon acquisition to be cash equivalents. These investments are stated at cost, which approximates fair value. The Company has an arrangement with a financial institution with which it has an existing banking relationship, whereby in exchange for the issuance of corporate credit cards, the Company agreed to obtain a certificate of deposit with this financial institution in the amount of $0.2 million as collateral for the balances borrowed on these cards (the Credit Card Program). The Company has classified the value of this certificate of deposit (including all interest earned thereon) within other assets in the accompanying balance sheets. The Company has the right to terminate the Credit Card Program at any time. Upon termination of the Credit Card Program and repayment of all outstanding balances owed, the Company may redeem the certificate of deposit (and all interest earned thereon). Cash, cash equivalents, and restricted cash presented in the accompanying condensed statements of cash flows consist of the following (in thousands):
|  | June 30, 2025 |  | December 31, 2024
Cash and cash equivalents |  | $ | 30,033 |  |  | $ | 22,036 |
Restricted cash |  | 200 |  |  | 200 |
Total cash, cash equivalents and restricted cash |  | $ | 30,233 |  |  | $ | 22,236 |
Long-Lived Assets The Company’s long-lived assets are comprised principally of its property and equipment and operating lease assets. The Company amortizes all finite-lived intangible assets over their respective estimated useful lives. Operating lease assets are amortized over the term of the leases. In considering whether long-lived assets are impaired, the Company combines its long-lived assets into groupings, a determination which is made principally on the basis of whether the assets are specific to a particular test offered or technology being developed. If the Company identifies a change in the circumstances related to its long-lived assets that indicates the carrying value of any such asset may not be recoverable, the Company will perform an impairment analysis. A long-lived asset is deemed to be impaired when the undiscounted cash flows expected to be generated by the asset (or asset group) are less than the asset’s carrying amount. Management’s estimates of future cash flows are impacted by projected test volume and levels of reimbursement, as well as expectations related to the future cost structure of the entity. Any required impairment loss would be measured as the amount by which the asset’s carrying value exceeds its fair value, and would be recorded as a reduction in the carrying value of the related asset and a charge to operating expense. Revenue Recognition Substantially all of the Company's revenue has been derived from sales of its testing products and is primarily comprised of a high volume of relatively low-dollar transactions. The Company primarily markets its testing products to rheumatologists and their physician assistants in the United States. The healthcare professionals who order the Company's testing products and to whom test results are reported are generally not responsible for payment for these products. The parties that pay for these services (each, a payor) consist of commercial payors (healthcare insurers), government payors (primarily Medicare and Medicaid), client payors (hospitals, other laboratories, etc.) and patient self-pay. The Company recognizes revenue in accordance with Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers and follows a five-step process to determine the amount and timing of revenue recognized: (1) identify the contract with the customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to performance obligations in the contract, and (5) recognize revenue when (or as) the performance obligation is satisfied. The Company's service is a single performance obligation that is completed upon the delivery of test results to the prescribing physician which triggers revenue recognition. Payors are generally billed at the Company's list price, unless a separate pricing contract is in place. Net revenues recognized consist of amounts billed net of allowances for differences between amounts billed and the estimated consideration the Company expects to receive from such payors. The process for estimating revenues and the ultimate collection of accounts receivable involves significant judgment and estimation. The Company follows a standard process, which considers historical denial and collection experience, insurance reimbursement policies and other factors, to estimate allowances and implicit price concessions. Adjustments are recorded in the current period as changes in estimates occur. Further adjustments to the allowances, based on actual receipts, are recorded upon settlement. Included in revenues for the three months ended June 30, 2025 and 2024 was a $0.1 million and a $3.1 million net revenue increase, respectively, associated with changes in estimated variable consideration related to performance obligations satisfied in previous periods. Included in revenues for the six months ended June 30, 2025 and 2024 was a $1.0 million and a $5.1 million net revenue increase, respectively, associated with changes in estimated variable consideration related to performance obligations satisfied in previous periods. The transaction price is estimated using an expected value method on a portfolio basis. 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's portfolios are grouped per payor (i.e. each individual commercial payor, Medicare, Medicaid, client payors, patient self-pay, etc.) and per test. Consideration may be constrained and excluded from the transaction price in situations where there is no contractually agreed upon reimbursement coverage or in absence of a predictable pattern and history of collectability with a payor. Accordingly, in such situations revenues are recognized on the basis of actual cash collections. Additionally, from time to time, the Company may issue refunds to payors for overpayments or amounts billed in error. Any refunds are accounted for as reductions in revenues in the condensed statements of operations as an element of variable consideration. The estimated expected refunds are accrued as a liability on the Company’s condensed balance sheets. Collection of the Company's net revenues from payors is normally a function of providing complete and correct billing information, along with any requested medical or other claims-related information to the healthcare insurers. This generally occurs within 30 to 90 days of billing, however, the amount and timing of any reimbursements or collections for the Company's billed tests may vary by payor and other circumstances. Contracts do not contain significant financing components based on the typical period of time between performance of services and collection of consideration. Amounts received prior to satisfying the above revenue recognition criteria are recognized as deferred revenue until all applicable revenue recognition criteria are met. Deferred revenue represented the portion of payments received that have not been earned. During the fourth quarter of 2024 and the first quarter of 2025, the Company entered into various work orders to perform diagnostic testing services including identifying and evaluating biomarkers, and received nonrefundable, upfront payments for these services. The Company had deferred revenue related to these contracts of $1.0 million and $0.7 million as of June 30, 2025 and December 31, 2024, respectively. The Company recognized revenue of $0.2 million out of the beginning deferred revenue balance during the six months ended June 30, 2025 and no revenue was recognized out of the beginning deferred revenue balance during the six months ended June 30, 2024. The Company expects to recognize revenue from unfulfilled performance obligations associated with service contracts within one year or less. Accounts Receivable and Allowance for Credit Losses The Company accrues an allowance for credit losses against its accounts receivable based on management’s current estimate of amounts that will not be collected. Management’s estimates are typically based on historical loss information adjusted for current conditions. The Company generally does not perform evaluations of the financial condition of the Company's customers and generally does not require collateral. The allowance for credit losses was $0.5 million and zero as of June 30, 2025 and 2024, respectively. Adjustments for implicit price concessions attributable to variable consideration, as discussed above, are incorporated into the measurement of the accounts receivable balances and are not part of the allowance for credit losses. Accounts receivable was $14.3 million and $7.8 million at June 30, 2025, and December 31, 2024, respectively. Loan Commitment Fees Loan commitment fees are generally included as a reduction of the proceeds from the outstanding debt. If there were no borrowings drawn on the related credit facility, the loan commitment fees are classified as assets until the related debt is drawn. The Company’s loan commitment fee is comprised of an upfront cash payment and a contingent obligation to issue future warrants to Perceptive in connection with the Credit Agreement (as defined below). The amounts have been recognized in prepaid expenses and other current assets for the short-term portion of $1.1 million and within other assets for the long-term portion of $0.8 million on the condensed balance sheets as of June 30, 2025. As the Company is not reasonably certain it will draw on the future debt tranches, the loan commitment fees are amortized ratably into interest expense over the outstanding draw periods. During the three and six months ended June 30, 2025, the Company recognized $0.2 million in non-cash interest expense related to the amortization of the loan commitment fees within the Company's condensed statements of operations. Stock-Based Compensation The Company recognizes compensation expense for all stock-based awards to employees and directors based on the grant date estimated fair values over the requisite service period of the awards (usually the vesting period) on a straight-line basis. The fair value of stock options and purchases under the Company's 2019 Employee Stock Purchase Plan (ESPP) is determined using the Black-Scholes-Merton (BSM) option pricing model, which requires management to make certain assumptions regarding a number of complex and subjective variables. Equity award forfeitures are recorded as they occur. The BSM option pricing model incorporates various inputs, including the fair value of the Company's common stock, expected volatility, expected term and risk-free interest rates. Volatility is based on the Company's historical calculated volatility since being publicly traded. The Company computes the historical volatility data using the daily closing prices of the Company’s common stock during the equivalent period that approximates the calculated expected term of the stock options. The weighted-average expected term of options was calculated using the simplified method, as the Company has concluded that its stock option exercise history does not provide a reasonable basis upon which to estimate the expected term. The risk-free interest rate for periods within the contractual term of the option is based on the U.S. Treasury yield in effect at the time of grant. The dividend yield is zero, as the Company has never declared or paid dividends and has no plans to do so in the foreseeable future. The fair value of each restricted stock unit (RSU) is determined on the grant date using the closing price of the Company's common stock on that date. The Company's RSUs generally vest in equal annual installments over four years from the date of grant or, for grants to new hires, date of hire. Vesting of the RSU is subject to the holder's continued service with the Company. The Company issues new shares of common stock to satisfy the RSUs upon vesting. Comprehensive Loss Comprehensive loss is defined as a change in equity of a business enterprise during a period, resulting from transactions from nonowner sources. There have been no items qualifying as other comprehensive loss and, therefore, for all periods presented, the Company's comprehensive loss was the same as its reported net loss. Net Loss Per Share Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common stock equivalents outstanding for the period determined using the treasury-stock and if-converted methods. The weighted-average number of shares used to compute basic and diluted shares includes shares issuable upon the exercise of pre-funded warrants at a nominal price. Potentially dilutive common stock equivalents are comprised of warrants for the purchase of common stock, stock options, RSUs outstanding under the Company's 2019 Incentive Award Plan (the 2019 Plan) and shares of the Company's common stock pursuant to the ESPP. For the three and six months ended June 30, 2025 and 2024, there is no difference in the number of shares used to calculate basic and diluted shares outstanding, as the inclusion of the potentially dilutive securities would be anti-dilutive. Potentially dilutive securities not included in the calculation of diluted net loss per share, because to do so would be anti-dilutive, are as follows (in common stock equivalent shares):
|  | June 30, 2025 |  | June 30, 2024
Warrants to purchase common stock |  | 580,339 |  |  | 409,108 |
Common stock options |  | 564,441 |  |  | 817,046 |
Restricted stock units |  | 1,679,624 |  |  | 1,679,469 |
Employee stock purchase plan |  | 54,454 |  |  | 38,299 |
Total |  | 2,878,858 |  |  | 2,943,922 |
Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (FASB), or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, Accounting Standards Updates (ASU) not included in the Company’s disclosures were assessed and determined to be either not applicable or are not expected to have a material impact on the Company's financial statements or disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09), which requires additional income tax disclosures in the rate reconciliation table for federal, state and foreign income taxes, in addition to more details about the reconciling items in some categories when items meet a certain quantitative threshold. ASU 2023-09 is effective for annual periods beginning after December 15, 2024 with early adoption permitted. This update will result in enhanced income tax disclosures, and the Company does not expect any impact to income tax expense. In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) (ASU 2024-03). This update requires entities to include more detailed information about the types of expenses, including purchases of inventory, employee compensation, depreciation, amortization, and depletion, in commonly presented expense captions such as cost of sales, research and development, and selling, general and administrative expenses. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of this standard on its financial statement presentation and disclosures.
