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 Condensed Consolidated Financial Statements herein 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, 2023 (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 seasonality in its business. Due to the annual reset of patient deductibles at the beginning of the year, the Company has historically experienced a decrease in test volumes and reduction in the average revenue per test for the six months ended June 30. For the six months ended June 30, 2024 and 2023, the Company did not experience this seasonality impact to the same extent as prior years. Additionally, operating results for the three and six months ended June 30, 2024 may not necessarily be indicative of results to be expected for any other interim period or for the full year and historical patterns of seasonality may continue in future periods. For example, the volume of testing is typically negatively impacted by the summer season, which is generally reflected in the quarter ended September 30.
Assets and Liabilities Held for Sale Policy	Assets and liabilities held for sale ("Net Assets held for Sale") represent receivables, inventory, intangibles, and other assets and liabilities that have met the criteria of "held for sale" accounting, as specified by Accounting Standards Codification ("ASC") 360, Property, Plant, and Equipment, and are recorded at the lower of carrying value or fair value less costs to sell. Fair value is based on the estimated proceeds from the sale of net assets and estimates of the costs to sell that include direct costs that are estimable and probable. Assets and liabilities classified as held for sale are expected to be sold within twelve months following their initial classification as held for sale.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2023, the Financial Accounting Standards Board ("FASB") issued accounting standards update ("ASU") 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which enhances the disclosures required for reportable segments in annual and interim consolidated financial statements. ASU 2023-07 is effective for the Company for annual reporting periods beginning after December 15, 2023 and for interim periods within fiscal years December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2023-07 on its segment disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires enhanced income tax disclosures, including disaggregation of information on the rate reconciliation table and disaggregated information related to income taxes paid. The amendments in ASU 2023-09 are effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of ASU 2023-09 on its income tax disclosures.
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, or cash flows from operations.
Revenue	The Company primarily generates revenue by performing genetic testing. Testing revenues are primarily derived from the following categories of products: Hereditary Cancer (MyRisk, BRACAnalysis, BRACAnalysis CDx), Tumor Profiling (MyChoice CDx, Prolaris, Precise Tumor, and EndoPredict), Prenatal (Foresight, Prequel, and SneakPeek), and Pharmacogenomics (GeneSight). Revenue is recorded at the estimated transaction price. The Company has determined that the communication of test results indicates transfer of control for revenue recognition purposes. Under ASC 606: Revenue from Contracts with Customers, an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company performs its obligation under a contract with a customer by processing tests and communicating the test results to customers, in exchange for consideration from the customer. The Company has the right to bill its customers upon the completion of performance obligations and thus does not record contract assets. Occasionally, customers make payments prior to the Company’s performance of its contractual obligations. When this occurs, the Company records a contract liability as Deferred revenue, which is included in Accrued liabilities in the Condensed Consolidated Balance Sheets. In accordance with ASC 606, the Company has elected not to disclose the aggregate amount of the transaction price allocated to remaining performance obligations for its contracts that are one year or less, as the revenue is expected to be recognized within the next year. Furthermore, the Company has elected not to disclose the aggregate amount of the transaction price allocated to remaining performance obligations for its agreements wherein the Company’s right to payment is in an amount that directly corresponds with the value of the Company’s performance to date. In determining the transaction price, the Company includes an estimate of the expected amount of consideration as revenue. The Company applies this method consistently for similar contracts when estimating the effect of any uncertainty on an amount of variable consideration to which it will be entitled. An estimate of transaction price does not include any estimated amount of variable consideration that is constrained. In addition, the Company considers all the information (historical, current, and forecast) that is reasonably available to identify possible consideration amounts. In determining the expected value, the Company considers the probability of the variable consideration for each possible scenario. The Company also has significant experience with historical discount patterns and uses this experience to estimate transaction prices. The estimate of revenue is affected by assumptions in payor behavior such as changes in payor mix, payor collections, current customer contractual requirements, and experience with collections from third-party payors. When assessing the total consideration for insurance carriers and patients, revenues are further constrained for estimated refunds. The Company reserves certain amounts in Accrued liabilities in the Company’s Condensed Consolidated Balance Sheets in anticipation of requests for refunds of payments made previously by insurance carriers, which are accounted for as reductions in revenues in the Condensed Consolidated Statements of Operations and Comprehensive Loss. Cash collections for certain tests delivered may differ from rates estimated, primarily driven by changes in the estimated transaction price due to contractual adjustments, obtaining updated information from payors and patients that was unknown at the time the performance obligation was met, and settlements with third-party payors. 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 June 30, 2024 and the three and six months ended June 30, 2023, the impact of the amounts to be recognized for previously delivered tests was not material to the Company's Condensed Consolidated Statements of Operations. During the six months ended June 30, 2024, the Company recognized $6.3 million in revenue, which resulted in a $0.07 impact to earnings per share for tests in which the performance obligation was met in prior periods, primarily driven by changes in the estimated transaction price. Additionally, during the six months ended June 30, 2024, the Company recognized $3.0 million in revenue due to a retroactive coverage change by a payor for one of its prenatal products. The Company applies the practical expedient related to costs to obtain or fulfill a contract since the amortization period for such costs will be one year or less. Accordingly, no costs incurred to obtain or fulfill a contract have been capitalized. The Company also applies the practical expedient for not adjusting revenue recognized for the effects of the time value of money. This practical expedient has been elected because the Company collects very little cash from customers under payment terms and the vast majority of payment terms have a payback period of less than one year.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company limits its exposure to loss by placing its cash in financial institutions with high credit ratings. The Company's cash may consist of deposits held with banks that may at times exceed federally insured limits of $250,000 per customer. Substantially all of the Company’s accounts receivable are with companies in the healthcare industry, U.S. and state governmental agencies, and individuals. The Company does not believe that receivables due from U.S. and state governmental agencies, such as Medicare, represent a credit risk since the related healthcare programs are funded by the U.S. and state governments.
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. All of the Company’s financial instruments are valued using quoted prices in active markets or based on other observable inputs. For Level 2 securities, the Company uses a third-party pricing service which provides documentation on an ongoing basis that includes, among other things, pricing information with respect to reference data, methodology, inputs summarized by asset class, pricing application and corroborative information. The fair value of the Company’s long-term debt, which it considers a Level 2 measurement, is estimated using discounted cash flow analyses, based on the Company’s current estimated incremental borrowing rates for similar borrowing arrangements.

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 Condensed Consolidated Financial Statements herein 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, 2023 (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 seasonality in its business. Due to the annual reset of patient deductibles at the beginning of the year, the Company has historically experienced a decrease in test volumes and reduction in the average revenue per test for the six months ended June 30. For the six months ended June 30, 2024 and 2023, the Company did not experience this seasonality impact to the same extent as prior years. Additionally, operating results for the three and six months ended June 30, 2024 may not necessarily be indicative of results to be expected for any other interim period or for the full year and historical patterns of seasonality may continue in future periods. For example, the volume of testing is typically negatively impacted by the summer season, which is generally reflected in the quarter ended September 30.

Assets and Liabilities Held for Sale Policy

Assets and liabilities held for sale ("Net Assets held for Sale") represent receivables, inventory, intangibles, and other assets and liabilities that have met the criteria of "held for sale" accounting, as specified by Accounting Standards Codification ("ASC") 360, Property, Plant, and Equipment, and are recorded at the lower of carrying value or fair value less costs to sell. Fair value is based on the estimated proceeds from the sale of net assets and estimates of the costs to sell that include direct costs that are estimable and probable. Assets and liabilities classified as held for sale are expected to be sold within twelve months following their initial classification as held for sale.

Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board ("FASB") issued accounting standards update ("ASU") 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which enhances the disclosures required for reportable segments in annual and interim consolidated financial statements. ASU 2023-07 is effective for the Company for annual reporting periods beginning after December 15, 2023 and for interim periods within fiscal years December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2023-07 on its segment disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires enhanced income tax disclosures, including disaggregation of information on the rate reconciliation table and disaggregated information related to income taxes paid. The amendments in ASU 2023-09 are effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of ASU 2023-09 on its income tax disclosures.

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, or cash flows from operations.

Revenue

The Company primarily generates revenue by performing genetic testing. Testing revenues are primarily derived from the following categories of products: Hereditary Cancer (MyRisk, BRACAnalysis, BRACAnalysis CDx), Tumor Profiling (MyChoice CDx, Prolaris, Precise Tumor, and EndoPredict), Prenatal (Foresight, Prequel, and SneakPeek), and Pharmacogenomics (GeneSight). Revenue is recorded at the estimated transaction price. The Company has determined that the communication of test results indicates transfer of control for revenue recognition purposes.

Under ASC 606: Revenue from Contracts with Customers, an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company performs its obligation under a contract with a customer by processing tests and communicating the test results to customers, in exchange for consideration from the customer. The Company has the right to bill its customers upon the completion of performance obligations and thus does not record contract assets. Occasionally, customers make payments prior to the Company’s performance of its contractual obligations. When this occurs, the Company records a contract liability as Deferred revenue, which is included in Accrued liabilities in the Condensed Consolidated Balance Sheets.

In accordance with ASC 606, the Company has elected not to disclose the aggregate amount of the transaction price allocated to remaining performance obligations for its contracts that are one year or less, as the revenue is expected to be recognized within the next year. Furthermore, the Company has elected not to disclose the aggregate amount of the transaction price allocated to remaining performance obligations for its agreements wherein the Company’s right to payment is in an amount that directly corresponds with the value of the Company’s performance to date.

In determining the transaction price, the Company includes an estimate of the expected amount of consideration as revenue. The Company applies this method consistently for similar contracts when estimating the effect of any uncertainty on an amount of variable consideration to which it will be entitled. An estimate of transaction price does not include any estimated amount of variable consideration that is constrained. In addition, the Company considers all the information (historical, current, and forecast) that is reasonably available to identify possible consideration amounts. In determining the expected value, the Company considers the probability of the variable consideration for each possible scenario. The Company also has significant experience with historical discount patterns and uses this experience to estimate transaction prices.

The estimate of revenue is affected by assumptions in payor behavior such as changes in payor mix, payor collections, current customer contractual requirements, and experience with collections from third-party payors. When assessing the total consideration for insurance carriers and patients, revenues are further constrained for estimated refunds. The Company reserves certain amounts in Accrued liabilities in the Company’s Condensed Consolidated Balance Sheets in anticipation of requests for refunds of payments made previously by insurance carriers, which are accounted for as reductions in revenues in the Condensed Consolidated Statements of Operations and Comprehensive Loss.

Cash collections for certain tests delivered may differ from rates estimated, primarily driven by changes in the estimated transaction price due to contractual adjustments, obtaining updated information from payors and patients that was unknown at the time the performance obligation was met, and settlements with third-party payors. 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 June 30, 2024 and the three and six months ended June 30, 2023, the impact of the amounts to be recognized for previously delivered tests was not material to the Company's Condensed Consolidated Statements of Operations. During the six months ended June 30, 2024, the Company recognized $6.3 million in revenue, which resulted in a $0.07 impact to earnings per share for tests in which the performance obligation was met in prior periods, primarily driven by changes in the estimated transaction price. Additionally, during the six months ended June 30, 2024, the Company recognized $3.0 million in revenue due to a retroactive coverage change by a payor for one of its prenatal products.

The Company applies the practical expedient related to costs to obtain or fulfill a contract since the amortization period for such costs will be one year or less. Accordingly, no costs incurred to obtain or fulfill a contract have been capitalized. The Company also applies the practical expedient for not adjusting revenue recognized for the effects of the time value of money. This practical expedient has been elected because the Company collects very little cash from customers under payment terms and the vast majority of payment terms have a payback period of less than one year.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company limits its exposure to loss by placing its cash in financial institutions with high credit ratings. The Company's cash may consist of deposits held with banks that may at times exceed federally insured limits of $250,000 per customer. Substantially all of the Company’s accounts receivable are with companies in the healthcare industry, U.S. and state governmental agencies, and individuals. The Company does not believe that receivables due from U.S. and state governmental agencies, such as Medicare, represent a credit risk since the related healthcare programs are funded by the U.S. and state governments.

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.

All of the Company’s financial instruments are valued using quoted prices in active markets or based on other observable inputs. For Level 2 securities, the Company uses a third-party pricing service which provides documentation on an ongoing basis that includes, among other things, pricing information with respect to reference data, methodology, inputs summarized by asset class, pricing application and corroborative information.

The fair value of the Company’s long-term debt, which it considers a Level 2 measurement, is estimated using discounted cash flow analyses, based on the Company’s current estimated incremental borrowing rates for similar borrowing arrangements.
