Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial information has been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC") for interim reporting purposes. The condensed consolidated financial statements are unaudited. The unaudited condensed consolidated financial statements reflect, in the opinion of the Company's management, all adjustments, consisting of only normal recurring adjustments, necessary for a fair presentation of financial position, results of operations, changes in equity, and comprehensive loss and cash flows for each period presented in accordance with United States generally accepted accounting principles (“U.S. GAAP”). All intercompany transactions and balances have been eliminated. These interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019. Certain prior year numbers were reclassified to conform with current year presentation. Such reclassification had no impact on the previously reported results of operations.
Recently Issued But Not Yet Adopted Accounting Pronouncements	Recently Issued But Not Yet Adopted Accounting Pronouncements In April 2012, the Jump-Start Our Business Startups Act (the “JOBS Act”) was signed into law. The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for an emerging growth company. As an emerging growth company, the Company may elect to adopt new or revised accounting standards when they become effective for non-public companies, which typically is later than when public companies must adopt the standards. The Company has elected to take advantage of the extended transition period afforded by the JOBS Act and, as a result, will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for emerging growth companies, which are the dates included below. In February 2015, the FASB issued Accounting Standards Update ("ASU") 2016-2, Leases (Topic 842), which amends the accounting guidance for leases and increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requires disclosures of key information about leasing arrangements. ASU 2016-2 initially mandated a modified retrospective transition method, however, in July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which amends ASU 2016-2, permitting entities the option to adopt this standard prospectively with a cumulative-effect adjustment to opening equity in the year of adoption and include required disclosures for prior periods but will not restate prior periods. The Company anticipates implementing the accounting guidance for leases using the alternative method beginning with the annual reporting period ending December 31, 2022 and interim reporting periods in 2023. The Company is in the process of evaluating the impact of adoption of the lease accounting guidance on the consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses: Measurement of credit Losses on Financial Instruments (ASU 2016-13), which amends the impairment model by requiring entities to use a forward looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables and available-for-sale debt securities. The standard is effective for the company beginning in the first quarter of 2023, with early adoption permitted. the Company is currently evaluating the expected impact of ASU 2016-13 on its financial statements. In August 2020, the FASB issued ASU No. 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 ("ASU 2020-06"), which simplifies accounting for convertible instruments by removing major seperation models required under current U.S. GAAP. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exceptions and also simplifies the diluted earnings per share calculation in certain areas. The standard is effective for public business entities, excluding entities eligible to be smaller reporting companies as defined by the SEC, for fiscal years and interim periods within those fiscal years beginning after December 15, 2021. For all other entities, the standard will be effective for fiscal years beginning after December 15, 2023. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, and adoption must be as of the beginning of the Company's annual fiscal year. The company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.
Lineagen Acquisition	Lineagen Acquisition On August 21, 2020, the Company, Alta Merger Sub, Inc., a wholly owned subsidiary of the Company (“Merger Sub”), Lineagen, a Delaware corporation, and Michael S. Paul, Ph.D., solely in his capacity as exclusive agent and attorney-in-fact of the securityholders of Lineagen, entered into an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the terms and conditions of the Merger Agreement, Merger Sub merged with and into Lineagen (the “Merger”) whereupon the separate corporate existence of Merger Sub ceased, with Lineagen continuing as the surviving corporation of the Merger as a wholly owned subsidiary of the Company. The Company accounted for its acquisition of Lineagen using the acquisition method of accounting pursuant to Accounting Standards Codification Topic 805, Business Combinations ("ASC 805"). Under ASC 805, the tangible and identifiable intangible assets acquired and liabilities assumed in a business combination are recorded based on their estimated fair values as of the acquisition date. Any excess purchase price over the estimated fair value assigned to the tangible and identifiable intangible assets acquired and liabilities assumed is recorded to goodwill. The Company based the estimated fair value of identifiable intangible assets acquired on independent valuations that use information and assumptions provided by the Company’s management. The use of alternative valuation assumptions, including estimated revenue projections, growth rates, cash flows, discount rates and useful lives could result in different purchase price allocations and amortization expense in current and future periods. Under ASC 805, acquisition-related transaction costs (such as advisory, legal, valuation, other professional fees) are expensed in the statements of operations in the periods incurred.
Long-Lived Assets (including Finite-Lived Purchased Intangible Assets)	Long-Lived Assets (including Finite-Lived Purchased Intangible Assets) Long-lived assets consist of property and equipment and purchased finite-lived intangible assets. The Company records property and equipment at cost, and records purchased finite-lived intangible assets based on their fair values at the date of acquisition. Property and equipment generally consist of laboratory equipment, computer and office equipment, furniture and fixtures, and leasehold improvements. Property and equipment are recorded at cost and depreciated or amortized using the straight-line method over the estimated useful lives of the assets (generally three to five years, or the remaining term of the lease for leasehold improvements, whichever is shorter). Repairs and maintenance costs are charged to expense as incurred. Intangible assets acquired in a business combination are recognized separately from goodwill and are initially recognized at their fair value at the acquisition date (which is regarded as their cost). Intangible assets are amortized over the estimated useful life of the asset on a basis that approximates the pattern of economic benefit. Intangible assets are reviewed for impairment if indicators of potential impairment exist. There was no indication of impairment of intangible assets for any of the periods presented. As a result of the Lineagen acquisition the Company recorded intangible assets, which consist of a trade name intangible and customer relationship intangible, which will be amortized using the straight-line method over the estimated useful lives of the assets of five years, which is consistent with the pattern of economic benefit of the assets. If the Company identifies a change in the circumstances related to its long-lived assets, such as property and equipment and intangible assets (other than goodwill), that indicates the carrying value of any such asset may not be recoverable, the Company will perform an impairment analysis. A long-lived asset (other than goodwill) is not recoverable when the undiscounted cash flows expected to be generated by the asset (or asset group) are less than the asset’s carrying amount. 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.

Goodwill	Goodwill Goodwill arises when the purchase price of an acquired business exceeds the fair value of the identifiable net assets acquired, with such excess recorded as goodwill on the balance sheet. Goodwill is not subsequently amortized. Goodwill is reviewed for impairment annually (during the fourth quarter) or more frequently if indications of impairment exist. In testing goodwill for impairment, the Company will first assess qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If the qualitative assessment indicates that it is more likely than not that the fair value of the reporting unit is less than its carrying value, then the Company will perform a quantitative impairment analysis by comparing the fair value of the reporting unit to the carrying value of the reporting unit, including goodwill. An impairment charge for goodwill is recognized for the amount by which the carrying value of the reporting unit exceeds its fair value, not to exceed the total goodwill allocated to the reporting unit.
Revenue Recognition for Diagnostic Services	Revenue Recognition for Diagnostic ServicesThe Company generates revenue by performing diagnostic testing services. Revenue from the completion of diagnostic testing services is recorded at the billed value less estimated contractual adjustments. The Company performs its obligation under a contract with a customer by processing diagnostic tests and communication of test results, which is the point at which the Company has determined control is transferred to the customer for revenue recognition purposes.
Net Loss Per Share	Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding for the period. Diluted net loss per share is computed by dividing the net loss by the weighted average number of common shares and common share equivalents outstanding for the period. Common stock equivalents are only included when their effect is dilutive. The Company’s potentially dilutive securities which include warrants and outstanding stock options under the Company’s equity incentive plan have been excluded from the computation of diluted net loss per share as they would be anti-dilutive to the net loss per share. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding due to the Company’s net loss position.
