Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying Condensed Consolidated Financial Statements for the Company have been prepared in accordance with United States ("U.S.") generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the accompanying financial statements contain all adjustments (consisting of normal and recurring accruals) necessary to present fairly all financial statements in accordance with GAAP. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with the Company’s audited Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 (the “Form 10-K”). The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. The Company has historically experienced some seasonality in its business, including due to factors such as the timing of deductibles resetting or being met. While the Company continues to experience periodic fluctuations in quarterly revenues, these variations are increasingly influenced by other factors such as the timing of customer activity, reimbursement dynamics, and broader market conditions. As a result, the Company believes that current operating results may not be indicative of results to be expected for any other interim period or for the full year.

Revenue	In determining the transaction price, the Company includes an estimate of the expected amount of consideration to be received. The estimate of revenue is affected by, among other factors, assumptions for changes in payor mix, payor collections, current customer contractual requirements, experience with collections from third-party payors, and changes in medical policies. When assessing the total consideration for insurance carriers and patients, revenue is further constrained for estimated refunds. The Company reserves certain amounts in Accrued liabilities in the Condensed Consolidated Balance Sheets in anticipation of requests for refunds of payments made previously by insurance carriers, which are accounted for as reductions in Revenue in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). Cash collections for certain tests delivered may differ from rates estimated due to changes in the estimated transaction price for contractual adjustments, obtaining updated information from payors and patients that was unknown at the time the performance obligation was met, settlements with third-party payors, or as a result of third-party payors disputing bills or denying payment for tests that the Company has performed, among other reasons. As a result of this new information, the Company updates its estimate of the amounts to be recognized for previously delivered tests. During the three months ended March 31, 2026 and 2025, the impact of the amounts to be recognized for tests in which the performance obligation was met in a prior period was not material to the Condensed Consolidated Statements of Operations.
Fair Value Measurements	The fair value of the Company’s financial instruments reflects the amounts that the Company estimates it will receive in connection with the sale of an asset or pay in connection with the transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). The fair value hierarchy prioritizes the use of inputs used in valuation techniques into the following three levels: Level 1—quoted prices in active markets for identical assets and liabilities. Level 2—observable inputs other than quoted prices in active markets for identical assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Some of the Company’s marketable securities primarily utilize broker quotes in a non-active market for valuation of these securities. Level 3—unobservable inputs. The carrying amounts of certain financial instruments—including cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses—approximate their fair values due to their short-term maturities. Additionally, the carrying value of our long-term debt as of March 31, 2026, approximates its fair value due to the debt’s floating interest rate based on prevailing market rates. The Company's fair value measurements related to impairment testing for goodwill and certain intangible assets were determined using Level 3 unobservable inputs; see Note 5, "Goodwill and Intangible Assets" for further discussion.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

The accompanying Condensed Consolidated Financial Statements for the Company have been prepared in accordance with United States ("U.S.") generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the accompanying financial statements contain all adjustments (consisting of normal and recurring accruals) necessary to present fairly all financial statements in accordance with GAAP. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with the Company’s audited Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 (the “Form 10-K”).

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period.

The Company has historically experienced some seasonality in its business, including due to factors such as the timing of deductibles resetting or being met. While the Company continues to experience periodic fluctuations in quarterly revenues, these variations are increasingly influenced by other factors such as the timing of customer activity, reimbursement dynamics, and broader market conditions. As a result, the Company believes that current operating results may not be indicative of results to be expected for any other interim period or for the full year.

Reclassifications

Certain prior period amounts have been reclassified to conform with the current period presentation. The reclassifications have no impact on the Company's total assets, total liabilities, stockholders' equity, net loss, comprehensive income (loss) or cash flows.

Revenue

In determining the transaction price, the Company includes an estimate of the expected amount of consideration to be received. The estimate of revenue is affected by, among other factors, assumptions for changes in payor mix, payor collections, current customer contractual requirements, experience with collections from third-party payors, and changes in medical policies. When assessing the total consideration for insurance carriers and patients, revenue is further constrained for estimated refunds. The Company reserves certain amounts in Accrued liabilities in the Condensed Consolidated Balance Sheets in anticipation of requests for refunds of payments made previously by insurance carriers, which are accounted for as reductions in Revenue in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).

Cash collections for certain tests delivered may differ from rates estimated due to changes in the estimated transaction price for contractual adjustments, obtaining updated information from payors and patients that was unknown at the time the performance obligation was met, settlements with third-party payors, or as a result of third-party payors disputing bills or denying payment for tests that the Company has performed, among other reasons. As a result of this new information, the Company updates its estimate of the amounts to be recognized for previously delivered tests. During the three months ended March 31, 2026 and 2025, the impact of the amounts to be recognized for tests in which the performance obligation was met in a prior period was not material to the Condensed Consolidated Statements of Operations.

Fair Value Measurements

The fair value of the Company’s financial instruments reflects the amounts that the Company estimates it will receive in connection with the sale of an asset or pay in connection with the transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). The fair value hierarchy prioritizes the use of inputs used in valuation techniques into the following three levels:

Level 1—quoted prices in active markets for identical assets and liabilities.

Level 2—observable inputs other than quoted prices in active markets for identical assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Some of the Company’s marketable securities primarily utilize broker quotes in a non-active market for valuation of these securities.

Level 3—unobservable inputs.

The carrying amounts of certain financial instruments—including cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses—approximate their fair values due to their short-term maturities. Additionally, the carrying value of our long-term debt as of March 31, 2026, approximates its fair value due to the debt’s floating interest rate based on prevailing market rates. The Company's fair value measurements related to impairment testing for goodwill and certain intangible assets were determined using Level 3 unobservable inputs; see Note 5, "Goodwill and Intangible Assets" for further discussion.
