Significant items subject to such estimates include the allowance for doubtful accounts calculated based on the historical uncollected balances applied to current outstanding accounts receivable balances, average selling price expected to be received from insurance payors, the operating right-of-use assets and the associated lease liabilities, the average useful life for property and equipment, deferred revenues associated with unsatisfied performance obligations, accrued liability for potential refund requests, stock-based compensation, the fair value of options, income tax uncertainties, and the expected consideration to be received from contracts with customers. These estimates and assumptions are based on management's best estimates and judgment. Management regularly evaluates its estimates and assumptions using historical experience and other factors, including contractual terms and statutory limits; however, actual results could differ from these estimates and could have an adverse effect on the Company's financial statements.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-style:italic;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="display:inline-block;text-align:left;text-indent:0pt;width:36pt;"/><i style="font-style:italic;">Revenue</i></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="display:inline-block;text-align:left;text-indent:0pt;width:36pt;"/>The total consideration which the Company expects to be entitled to from patients and insurance carriers in exchange for the Company's products is determined is a significant estimate when the Company calculates Average Selling Price based on the contractual pricing agreed to with each insurance carrier for each test (CPT code) performed adjusted for variable consideration related to historical percent of cases allowed, historical percent of patient responsibility collected, and historical percent of contract price collected from insurance carriers. The Company uses the expected-value approach of estimating variable consideration. The Company also considers recent trends, past events not expected to recur, and future known changes such as anticipated contractual pricing changes or insurance coverages. For insurance carriers with similar reimbursement characteristics, the Company uses a portfolio approach to estimate the effects of variable consideration. The Company also applies a constraint to the estimated variable consideration when it assesses it is probable that a significant reversal in the amount of cumulative revenue may occur in future periods. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="display:inline-block;text-align:left;text-indent:0pt;width:36pt;"/>When assessing the total consideration for insurance carriers and patients, a certain percentage of revenues is further constrained for estimated refunds.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-style:italic;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="display:inline-block;text-align:left;text-indent:0pt;width:36pt;"/><i style="font-style:italic;">Stock-based compensation</i></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-style:italic;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="display:inline-block;text-align:left;text-indent:0pt;width:36pt;"/>The Company’s stock-based compensation relates to stock options, restricted stock units (“RSUs”), performance-based awards, market-based awards, and stock purchase rights under an Employee Stock Purchase Plan (“ESPP”).<span style="display:inline-block;width:10.63pt;"/></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="display:inline-block;text-align:left;text-indent:0pt;width:36pt;"/>Stock based compensation granted to the Company’s employees is measured at the grant date based on the fair value of the award. The fair value is recognized as expense over the requisite service period, which is generally the vesting period or estimated performance period of the respective awards. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="display:inline-block;text-align:left;text-indent:0pt;width:36pt;"/>The Company uses the Black‑Scholes option‑pricing model to estimate the fair value of stock options issued to employees and non-employees. Stock-based compensation expense for stock-based awards are based on their grant date fair value. The fair value of stock option awards is recognized as compensation expense on a straight-line basis over the </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">requisite service period in which the awards are expected to vest and forfeitures are estimated based on historical trends at the time of grant and revised as necessary. Stock option awards that include a service condition and a performance condition are considered expected to vest when the performance condition is probable of being met. The Black-Scholes model considers several variables and assumptions in estimating the fair value of stock-based awards. These variables include the per share fair value of the underlying common stock, exercise price, expected term, risk-free interest rate, expected annual dividend yield and the expected stock price volatility over the expected term. For all stock options granted, we calculate the expected term using the simplified method for “plain vanilla” stock option awards. We determine expected volatility using the historical volatility of the stock price of similar publicly traded peer companies. The risk-free interest rate is based on the yield available on U.S. Treasury zero-coupon issues similar in duration to the expected term of the equity-settled award.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="display:inline-block;text-align:left;text-indent:0pt;width:36pt;"/>The Company determines the fair value of RSUs based on the closing price of our stock price, which is listed on Nasdaq, at the date of the grant. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="display:inline-block;text-align:left;text-indent:0pt;width:36pt;"/>For stock options and performance-based awards that vest upon meeting performance conditions or market conditions in combination with performance conditions, the Company derives the requisite service period from the grant date to the date it is probable that the vesting conditions will be met. The requisite service period is considered to be a significant accounting estimate. For stock options with market conditions, the Company derives the requisite service period using the Monte Carlo simulation model.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="display:inline-block;text-align:left;text-indent:0pt;width:36pt;"/>The Monte Carlo simulation model is used to estimate the fair value of market-based condition awards. The model requires the input of the Company's expected stock price and peer stock price volatility, the expected term of the awards, and a risk-free interest rate. Determining these assumptions requires significant judgment.

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Tax benefits are recognized when it is more likely than not that a tax position will be sustained during an audit. Deferred tax assets are reduced by a valuation allowance if current evidence indicates that it is considered more likely than not that these benefits will not be realized.

The Company uses judgment to analyze and determine if the composition of its inventory is obsolete, slow-moving or unsalable and frequently reviews such determinations. A write down of specifically identified unusable, obsolete, slow-moving or known unsalable inventory in the period is first recognized by using a number of factors including product expiration dates </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">and scrapped inventory. Any write-down of inventory to net realizable value establishes a new cost basis and will be maintained even if certain circumstances suggest the inventory is recoverable in subsequent periods. Costs associated with the write-down of inventory are recorded to cost of revenue on our consolidated statements of operations. The Company makes assumptions about future demand, market conditions and the release of new products that may supersede older products. However, if actual market conditions are less favorable than anticipated, additional inventory write-downs may be required.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="display:inline-block;text-align:left;text-indent:0pt;width:36pt;"/><i style="font-style:italic;">Investments and financial instruments</i></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="display:inline-block;text-align:left;text-indent:0pt;width:36pt;"/><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="display:inline-block;text-align:left;text-indent:0pt;width:36pt;"/>The Company classifies its investments as Level 1 or 2 within the fair value hierarchy. Fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets that the Company has the ability to access. Fair values determined by Level 2 inputs utilize data points that are observable such as quoted prices, interest rates and yield curves. The Company holds Level 2 securities which are initially valued at the transaction price and subsequently valued by a third-party service provider using inputs other than quoted prices that are observable either directly or indirectly, such as yield curve, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for the underlying instruments or debt, broker and dealer quotes, as well as other relevant economic measures.

The Company estimates the incremental borrowing rate of its leases based on corporate bonds with a similar credit rating as the Company and a similar bond term as the lease term as of the approximate lease commencement date.

Depreciation and amortization is calculated using the straight-line method over the estimated useful lives of the assets, which are generally three to five years determined by the classification of the property and equipment class in accordance with the Company’s fixed asset policy. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the assets or the remaining term of the lease, whichever is shorter. The Company periodically reviews the useful lives assigned to property and equipment placed in service in accordance with the Company’s fixed asset policy and changes the estimates of useful lives to reflect the results of such reviews.

Estimates consist of historical trends, analytical procedures, review of supporting documentation, inquiries with supply partners and vendors, and other relevant assumptions. Estimates are used in several areas including, but not limited to, estimates of progress to date for certain contacts with vendors, liabilities related to clinical trials, reserves associated with insurance and general overpayments, and the provision for income taxes. Although the Company believe its estimates, assumptions, and judgment are reasonable, it is based upon information presently available and are subject to change.</p>
