Going Concern [Abstract]
Operating Matters and Liquidity	Note 2—Operating Matters and Liquidity The Company has experienced net operating losses since its inception through June 30, 2013. The Company had net losses of $5.1 million and $5.0 million for the years ended December 31, 2012 and 2011, respectively, and $3.0 million for the six months ended June 30, 2013, contributing to an accumulated deficit of $110.7 million as of June 30, 2013. The Company continues to take steps to reduce operating costs, including genetic test processing costs as well as general and administrative expenses. Cost savings are achieved through test process improvements, reductions in personnel and the subleasing of underutilized rental space. Management believes that the current laboratory space is adequate to process high volumes of genetic tests. As more fully discussed in Note 8 herein, on May 17, 2013, the Company entered into a Common Stock Purchase Agreement with various accredited investors, pursuant to which the Company sold an aggregate of 43,715,847 shares of its common stock in a private placement transaction, at a price of $0.2745 per share for gross proceeds of $12,000,000. The investors also received warrants to purchase up to an aggregate of 32,786,885 shares of common stock at an exercise price of $0.2745 per share. The warrants are exercisable as to 63% of the shares immediately and as to 37% of the shares following receipt of shareholder approval of an increase in the number of authorized shares of common stock from 150,000,000 to 300,000,000, and have a term of seven years from the date they become exercisable. The Company’s financial statements have been prepared assuming that it will continue as a going concern which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company expects to incur additional losses in 2013 and, accordingly, is dependent on the recent financing and potential revenue to fund its operations in the commercial launch of the PST^® test with Renaissance Health Services Corporation (“RHSC”), the parent corporation of eight Delta Dental member companies operating in their eight respective states. The Company currently believes RHSC may begin offering dental plans that incorporate our genetic PST^® test for plan years beginning January 1, 2014. The timing of any revenues that we may receive under this agreement is dependent upon the timing of the offering of such plans, which timing is very uncertain at this time, and is contingent upon a number of factors, including RHSC’s affiliates’ ability to develop such plans and to develop a viable market for such plans. The Company expects to have the cash resources necessary, for at least the next twelve months, to support the launch of the PST genetic test in dental offices in collaboration with RHSC in 2014.
