Summary of Significant Accounting Policies [Abstract]  
Use of Estimates

Use of Estimates

The Company prepares its consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. These principles require management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, together with amounts disclosed in the related notes to the consolidated financial statements. Actual results and outcomes may differ from management’s estimates, judgments and assumptions. Significant estimates, judgments and assumptions used in these consolidated financial statements include, but are not limited to, those related to revenues, accounts receivable and related allowances, contingencies, useful lives and recovery of long-term assets, income taxes, and the fair value of stock-based compensation. These estimates, judgments, and assumptions are reviewed periodically and the effects of material revisions in estimates are reflected in the consolidated financial statements prospectively from the date of the change in estimate.

Revenue Recognition

Revenue Recognition

The Company recognizes revenues when (a) the price is fixed or determinable, (b) persuasive evidence of an arrangement exists, (c) the service is performed and (d) collectability of the resulting receivable is reasonably assured.

The Company’s specialized diagnostic services are performed based on a written test requisition form or electronic equivalent and revenues are recognized once the diagnostic services have been performed, and the results have been delivered to the ordering physician. These diagnostic services are billed to various payers, including Medicare, commercial insurance companies, other directly billed healthcare institutions such as hospitals and clinics, and individuals. The Company reports revenues from contracted payers, including Medicare, certain insurance companies and certain healthcare institutions, based on the contractual rate, or in the case of Medicare, published fee schedules. The Company reports revenues from non-contracted payers, including certain insurance companies and individuals, based on the amount expected to be collected. The difference between the amount billed and the amount estimated to be collected from non-contracted payers is recorded as an allowance to arrive at the reported net revenues. The expected revenues from non-contracted payers are based on the historical collection experience of each payer or payer group, as appropriate. The Company records revenues from patient pay tests net of a large discount and as a result recognizes minimal revenue on those tests. The Company regularly reviews its historical collection experience for non-contracted payers and adjusts its expected revenues for current and subsequent periods accordingly.

Cost of Revenue

Cost of Revenue

Cost of revenue includes payroll and payroll related costs for performing tests, depreciation of laboratory equipment, rent for laboratory facilities, laboratory reagents, probes and supplies, and delivery and courier costs relating to the transportation of specimens to be tested.

Advertising Costs

Advertising Costs

Advertising costs are expensed at the time they are incurred and are not material for the years ended December 31, 2012 and 2011, respectively.

Research and Development

Research and Development

Research and development (“R&D”) costs are expensed as incurred. R&D expenses consist of cash and equity compensation and benefits for R&D personnel, amortization of intangibles, related supplies, inventory and payment for samples to complete validation studies. These expenses were incurred to develop new genetic tests.

Fair Value Measurements

Fair Value Measurements

The Company determines fair value measurements used in its consolidated financial statements based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants exclusive of any transaction costs, as determined by either the principal market or the most advantageous market.

Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy. The basis for fair value measurements for each level within the hierarchy is described below with Level 1 having the highest priority and Level 3 having the lowest.

Level 1: Quoted prices in active markets for identical assets or liabilities.

Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets.

Level 3: Valuations derived from valuation techniques in which one or more significant inputs are unobservable.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are reported, net of an allowance for doubtful accounts, which is estimated based on the aging of accounts receivable with each payer category and the historical data on bad debts in these aging categories. In addition, the allowance is adjusted periodically for other relevant factors, including regularly assessing the state of our billing operations in order to identify issues which may impact the collectability of receivables or allowance estimates. Revisions to the allowance are recorded as an adjustment to bad debt expense within general and administrative expenses. After appropriate collection efforts have been exhausted, specific receivables deemed to be uncollectible are charged against the allowance in the period they are deemed uncollectible. Recoveries of receivables previously written-off are recorded as credits to the allowance. Our estimates of net revenue are subject to change based on the contractual status and payment policies of the third party payers with whom we deal. We regularly refine our estimates in order to make our estimated revenue as accurate as possible based on our most recent collection experience with each third party payer.

Statements of Cash Flows

Statements of Cash Flows

For purposes of the statements of cash flows, we consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Fair Value of Financial Instruments and Concentrations of Credit Risk

Fair Value of Financial Instruments and Concentrations of Credit Risk

The carrying value of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued expenses and other liabilities, amounts outstanding under our revolving credit facility, and other current assets and liabilities are considered reasonable estimates of their respective fair values due to their short-term nature. The Company maintains its cash and cash equivalents with domestic financial institutions that the Company believes to be of high credit standing. The Company believes that, as of December 31, 2012, its concentration of credit risk related to cash and cash equivalents was not significant. The carrying value of the Company’s long-term capital lease obligations approximates its fair value based on the current market conditions for similar instruments.

Concentrations of credit risk with respect to revenue and accounts receivable are primarily limited to certain clients to whom the Company provides a significant volume of its services, and to specific payers of our services such as Medicare and individual insurance companies. The Company’s client base consists of a large number of geographically dispersed clients diversified across various customer types. For the years ended December 31, 2012 and 2011, a large oncology practice with multiple locations accounted for 14.9% and 11.3% respectively, of total revenue. All other clients were less than 5% of total revenue individually.

The Company orders the majority of its FISH probes from one vendor and as a result of their dominance of that marketplace and the absence of any competitive alternatives, if they were to have a disruption and not have inventory available it could have a material effect on our business. This risk cannot be completely offset due to the fact that they have patent protection which limits other vendors from supplying these probes.

Inventories

Inventories

Inventories, which consist principally of testing supplies, are valued at the lower of cost or market, using the first-in, first-out method (FIFO).

Other Current Assets

Other Current Assets

As of December 31, 2012 and 2011, other current assets consist of prepaid expenses of approximately $820,000 and $824,000, respectively, and Lee County, Florida economic development tax credit of $0 and $130,000 respectively.

Property and Equipment

Property and Equipment

Property and equipment are recorded at cost, net of accumulated depreciation and amortization. Property and equipment generally includes purchases of items with a cost greater than $1,000 and a useful life greater than one year. Depreciation and amortization are computed on the straight line basis over the estimated useful lives of the assets. Leasehold improvements and property and equipment under capital leases are amortized over the shorter of the related lease terms or their estimated useful lives. Costs incurred in connection with the development of internal-use software are capitalized in accordance with the accounting standard for internal-use software, and are amortized over the expected useful life of the software.

The Company periodically reviews the estimated useful lives of property and equipment. Changes to the estimated useful lives are recorded prospectively from the date of the change. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in income (loss) from operations. Repairs and maintenance costs are expensed as incurred.

Intangible Assets

Intangible Assets

 

Intangible assets with finite useful lives are recorded at fair value which is our cost, less accumulated amortization. Amortization is recognized over the estimated useful lives of the assets. The Company’s intangible assets are related to our license agreement with Health Discovery Corporation (see Note E – Intangible Assets).

Recoverability and Impairment of Long-Lived Assets

Recoverability and Impairment of Long-Lived Assets

We review our long-lived assets for recoverability if events or changes in circumstances indicate the assets may be impaired. This circumstance exists when the carrying amount of the asset exceeds the sum of the undiscounted cash flows expected to result from its use and eventual disposition. At December 31, 2012, we believe the carrying value of our long-lived assets is recoverable.

Income Taxes

Income Taxes

We compute income taxes in accordance with ASC Topic 740 Income Taxes. Under ASC-740, deferred taxes are recognized for the tax consequences of temporary differences by applying enacted statutory rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. Also, the effect on deferred taxes of a change in tax rates is recognized in income in the period that included the enactment date. Temporary differences between financial and tax reporting arise primarily from the use of different depreciation methods and lives for property and equipment and recognition of bad debts and various other expenses that have been allowed for or accrued for financial statement purposes but are not currently deductible for income tax purposes.

We annually evaluate tax positions that have been taken or are expected to be taken in our tax returns, and record a liability for uncertain tax positions. We follow a two-step approach to recognizing and measuring uncertain tax positions. First, tax positions are recognized if the weight of available evidence indicates that it is more likely than not that the position will be sustained upon examination, including resolution of related appeals or litigation processes, if any. Second, the tax position is measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon settlement. We recognize interest and penalties related to unrecognized tax benefits in the provision for income taxes in the accompanying consolidated financial statements. As of December 31, 2012 and 2011, we do not believe we had any significant uncertain tax positions nor did we have any provision for interest or penalties related to such positions.

Stock-Based Compensation

Stock-Based Compensation

We account for option and stock awards under the Amended Plan in accordance with ASC Topic 718 Compensation – Stock Compensation, which requires the measurement and recognition of compensation expense in the Company’s statement of operations for all share-based option and stock awards, based on estimated grant-date fair values.

ASC Topic 718 requires us to estimate the fair value of stock-based option awards on the date of grant using an option-pricing model. The grant-date fair value of the award is recognized as expense over the requisite service period using the straight-line method. In accordance with ASC Topic 718, the estimated stock-based compensation expense to be recognized is reduced by stock option forfeitures.

We estimate the grant-date fair value of stock-based option awards using a trinomial lattice model. This model is affected by our stock price on the date of the grant as well as assumptions regarding a number of highly complex and subjective variables. These variables include the expected term of the option, expected risk-free rates of return, the expected volatility of our common stock, and expected dividend yield, each of which is more fully described below. The assumptions for expected term and expected volatility are the two assumptions that significantly affect the grant date fair value.

Expected Term: The expected term of an option is the period of time that the option is expected to be outstanding. The average expected term is determined using a trinomial lattice simulation model.

 

Risk-free Interest Rate: We base the risk-free interest rate used in the trinomial lattice valuation method on the implied yield at the grant date of the U.S. Treasury zero-coupon issue with an equivalent term to the stock-based award being valued. Where the expected term of a stock-based award does not correspond with the term for which a zero coupon interest rate is quoted, we use the nearest interest rate from the available maturities.

Expected Stock Price Volatility: Effective January 1, 2006 until December 31, 2009, we evaluated the assumptions used to estimate volatility and determined that, under SAB 107, we should use a blended average of our volatility and the volatility of certain peer companies. We believe that the use of this blended average peer volatility which was more reflective of market conditions and a better indicator of our expected volatility due to the limited trading history available for our Company since its last change of control, prior to which we operated under a different business model. Effective January 1, 2010 since we had sufficient historical data since our last change of control we began to use our own historical weekly volatility because that was more reflective of market conditions.

Dividend Yield: Because we have never paid a dividend and do not expect to begin doing so in the foreseeable future, we have assumed a 0% dividend yield in valuing our stock-based awards.

Tax Effects of Stock-Based Compensation

Tax Effects of Stock-Based Compensation

We will only recognize a tax benefit from windfall tax deductions for stock-based awards in additional paid-in capital if an incremental tax benefit is realized after all other tax attributes currently available have been utilized.

Net Income (Loss) Per Common Share

Net Income (Loss) Per Common Share

We compute net income or (loss) per share in accordance with ASC Topic 260 Earnings Per Share. Under the provisions of ASC 260, basic net income (loss) per share is computed by dividing the net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted average number of common shares outstanding during the applicable period, plus the dilutive effect of potential common stock. Potential common stock consists of shares issuable pursuant to stock options and warrants. Diluted net loss per share is computed by dividing the net loss for the period by the weighted average number of common and common equivalent shares outstanding during the period.
