Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization, Description of Business, Basis of Presentation, Acquisitions and Recent Accounting Pronouncements | Organization, Description of Business, Basis of Presentation, Acquisitions and Recent Accounting Pronouncements We are an emerging leader in the field of personalized medicine, enabling precision medicine in the field of oncology through our diagnostic products and services and molecular markers. We develop, commercialize and provide molecular- and biomarker-based tests and services that enable physicians to personalize the clinical management of each individual patient by providing genomic information to better diagnose, monitor and inform cancer treatment and that enable biopharmaceutical companies engaged in oncology trials to better select candidate populations and reduce adverse drug reactions by providing information regarding genomic factors influencing subject responses to therapeutics. We have a comprehensive, disease-focused oncology testing portfolio. Our tests and techniques target a wide range of cancers, covering eight of the top ten cancers in prevalence in the United States, with additional unique capabilities offered by our Tissue of Origin® test for identifying difficult to diagnose tumor types or poorly differentiated metastatic disease. We were incorporated in the State of Delaware on April 8, 1999 and have offices and state-of-the-art laboratories located in California, New Jersey, North Carolina, Shanghai (China), and Hyderabad (India). Our laboratories comply with the highest regulatory standards as appropriate for the services they deliver including CLIA, CAP, NY State, California State and NABL (India). Our services are built on a foundation of world-class scientific knowledge and intellectual property in solid and blood-borne cancers, as well as strong academic relationships with major cancer centers such as Memorial Sloan-Kettering, Mayo Clinic, and the National Cancer Institute. Basis of Presentation The accompanying unaudited condensed financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions for interim reporting as prescribed by the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary to make the financial statements not misleading have been included. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the audited consolidated financial statements as of and for the year ended December 31, 2015 , filed with the Securities and Exchange Commission on March 10, 2016. The consolidated balance sheet as of December 31, 2015 , included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP. Interim financial results are not necessarily indicative of the results that may be expected for any future interim period or for the year ending December 31, 2016 . Liquidity and Going Concern We believe that our current cash will support operations for at least the next 6 months. We are actively discussing opportunities for additional equity or debt financing, and we are taking steps to improve our operating cash flow. We can provide no assurances that our current actions will be successful or that any additional sources of financing will be available to us on favorable terms, if at all, when needed. Our forecast of the period of time through which our current financial resources will be adequate to support our operations and the costs to support our general and administrative, sales and marketing and research and development activities are forward-looking statements and involve risks and uncertainties. The continuation of the Company as a going concern is dependent on the ability of the Company to obtain necessary debt and/or equity financing to continue operations. These interim consolidated financial statements do not include any adjustments to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. Acquisition of Response Genetics, Inc. On October 9, 2015, we acquired substantially all the assets and assumed certain liabilities of Response Genetics, Inc. (“Response Genetics”), with its principal place of business in California, in a transaction valued at approximately $12.9 million , comprised of $7.5 million in cash and 788,584 shares of the Company’s common stock, with the common stock being valued at $5.4 million . The results of operations for the three and six months ended June 30, 2016 include the operations of Response Genetics, which accounted for approximately $2,044,000 and $4,207,000 of the Company’s consolidated revenue, respectively. The net loss of Response Genetics cannot be determined, as its operations are integrated with Cancer Genetics. 2016 Offering On May 25, 2016, we sold 2,467,820 shares of common stock in a public offering and warrants to purchase 1,233,910 shares of common stock in a concurrent private placement. These offerings resulted in gross proceeds of $5 million . We sold 2,150,000 shares of common stock and warrants to purchase 1,075,000 shares of common stock to certain institutional investors at a combined offering price of $2.00 per common share, and our Chairman of the Board, John Pappajohn, purchased 317,820 shares of common stock and warrants to purchase 158,910 shares of common stock at a combined offering price of $2.2025 per common share. In addition, we issued warrants to purchase an aggregate of 123,391 shares of common stock to the placement agent. Subject to certain ownership limitations, the warrants will be initially exercisable commencing six months from the issuance date at an exercise price equal to $2.25 per share of common stock. The warrants are exercisable for five years from the initial exercise date. All references to the sales of common stock and warrants mentioned in this paragraph are referred to as the “2016 Offering.” Recent Accounting Pronouncements In March 2016, the FASB issued ASU 2016-09 “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” This standard requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid in capital pools. The guidance also allows for the employer to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. The guidance is effective in 2017 with early adoption permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and the timing of adoption. |

The table above includes approximately $1,078,000 of biopharma revenue and approximately $3,129,000 of clinical services revenue from our acquisition of Response Genetics for the six months ended June 30, 2016 . Accounts receivable by service type at June 30, 2016 and December 31, 2015 consists of the following (in thousands): June 30, December 31, Biopharma Services $ 5,144 $ 3,238 Clinical Services 7,119 3,733 Discovery Services 345 314 Allowance for doubtful accounts (664 ) (664 ) $ 11,944 $ 6,621 At June 30, 2016 , accounts receivable includes approximately $1,425,000 of unbilled revenue for clinical services provided by our location in California. Allowance for Doubtful Accounts (in thousands) Balance, December 31, 2015 $ 664 Additions to allowance for doubtful accounts — Balance, June 30, 2016 $ 664 Revenue for Biopharma Services are customized solutions for patient stratification and treatment selection through an extensive suite of DNA-based testing services. Clinical Services are tests performed to provide information on diagnosis, prognosis and theranosis of cancers to guide patient management. These tests can be billed to Medicare, another third party insurer or the referring community hospital or other healthcare facility. Discovery Services are services that provide the tools and testing methods for companies and researchers seeking to identify new DNA-based biomarkers for disease. The breakdown of our Clinical Services revenue (as a percent of total revenue) is as follows: Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Medicare 12% 7% 13% 7% Other insurers 17% 6% 19% 6% Other healthcare facilities 7% 9% 6% 8% 36% 22% 38% 21% We have historically derived a significant portion of our revenue from a limited number of test ordering sites. Test ordering sites account for all of our Clinical Services and Biopharma Services revenue. Our test ordering sites are largely hospitals, cancer centers, reference laboratories, physician offices and biopharmaceutical companies. Oncologists and pathologists at these sites order the tests on behalf of the needs of their oncology patients or as part of a clinical trial sponsored by a biopharmaceutical company in which the patient is being enrolled. We generally do not have formal, long-term written agreements with such test ordering sites, and, as a result, we may lose a significant test ordering site at any time. The top five test ordering sites during the three months ended June 30, 2016 and 2015 accounted for 40% and 61% , respectively, of our testing volumes, with 6% and 22% , respectively, of the volume coming from community hospitals. During the three months ended June 30, 2016 , there were two biopharmaceutical companies which accounted for approximately 15% and 11% of our total revenue, respectively. During the three months ended June 30, 2015 , there was one biopharmaceutical company which accounted for approximately 25% of our total revenue. The top five test ordering sites during the six months ended June 30, 2016 and 2015 accounted for 38% and 66% respectively, of our testing volumes, with 7% and 23% , respectively, of the volume coming from community hospitals. During the six months ended June 30, 2016 , there were two biopharmaceutical companies which accounted for approximately 13% and 11% of our total revenue, respectively. During the six months ended June 30, 2015 , there were two biopharmaceutical companies which accounted for approximately 26% and 14% of our total revenue, respectively. |

Debt Disclosure [Abstract] | |
Bank Term Note and Line of Credit | Bank Term Note and Line of Credit On May 7, 2015, we entered into a debt financing facility with Silicon Valley Bank (“SVB”). The SVB credit facility provides for a $6.0 million term note (“Term Note”) and a revolving line of credit (“Line of Credit”) for an amount not to exceed the lesser of (i) $4.0 million or (ii) an amount equal to 80% of eligible accounts receivable. The Term Note requires interest-only payments through April 30, 2016 and beginning May 1, 2016, monthly principal payments of approximately $167,000 will be required plus interest through maturity on April 1, 2019 . The interest rate of the Term Note is the Wall Street Journal prime rate plus 2% , with a floor of 5.25% ( 5.50% at June 30, 2016 ) and an additional deferred interest payment of $180,000 will be due upon maturity. The Line of Credit requires monthly interest-only payments of the Wall Street Journal prime rate plus 1.5% ( 5.00% at June 30, 2016 ) and matures on May 7, 2017 . The loan agreement requires maintenance of certain financial ratios and grants SVB a first security interest in substantially all Company assets (other than our intellectual property). At June 30, 2016 the principal balance of the Term Note was approximately $5,667,000 and the principal balance of the Line of Credit was $0 . On January 28, 2016, the Line of Credit was amended with SVB and we are no longer able to draw on the Line of Credit until we raise approximately $8 million of additional equity. On June 3, 2016, the Company delivered its April 2016 reporting package to SVB showing the Company was in technical default with SVB due to violating a liquidity covenant. As discussed in Note 1, the Company raised $5 million in May of 2016. The Company was in compliance with all covenants in May and June of 2016. SVB has waived the April 2016 technical default. The following is a summary of long-term debt (in thousands): June 30, 2016 December 31, 2015 Term Note, principal balance $ 5,667 $ 6,000 Less unamortized debt issuance costs 19 25 Term Note, net 5,648 5,975 Less current maturities 2,000 1,333 Long-term portion $ 3,648 $ 4,642 Principal maturities of the Term Note as of June 30, 2016 are as follows: 2016 (remaining six months) - $1,000,000 ; 2017 - $2,000,000 ; 2018 - $2,000,000 ; 2019 - $666,667 . |

Stock-Based Compensation | Stock-Based Compensation We have two equity incentive plans: the 2008 Stock Option Plan (the “2008 Plan”) and the 2011 Equity Incentive Plan (the “2011 Plan”, and together with the 2008 Plan, the “Stock Option Plans”). The Stock Option Plans are meant to provide additional incentive to officers, employees and consultants to remain in our employment. Options granted are generally exercisable for up to 10 years . At June 30, 2016 , 921,276 shares remain available for future awards under the 2011 Plan and 112,055 shares remain available for future awards under the 2008 Plan. As of June 30, 2016 , no stock appreciation rights and 275,500 shares of restricted stock have been awarded under the Stock Option Plans. A summary of employee and non-employee stock option activity for the six months ended June 30, 2016 is as follows: Options Outstanding Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Number of Shares (in thousands) Weighted- Average Exercise Price Outstanding January 1, 2016 1,961 $ 10.55 7.68 $ — Canceled or expired (69 ) 9.78 Outstanding June 30, 2016 1,892 $ 10.57 7.13 $ — Exercisable June 30, 2016 1,173 $ 10.43 6.46 $ — On July 19, 2016, the Company granted employees incentive stock options to purchase 181,800 shares of the Company’s common stock at an exercise price of $2.02 per share with vesting over a period of 2.5 to 5 years. Aggregate intrinsic value represents the difference between the estimated fair value of our common stock and the exercise price of outstanding, in-the-money options. As of June 30, 2016 , total unrecognized compensation cost related to non-vested stock options granted to employees was $3,639,078 which we expect to recognize over the next 2.61 years. As of June 30, 2016 , total unrecognized compensation cost related to non-vested stock options granted to non-employees was $57,000 which we expect to recognize over the next 1.51 years. The estimate of unrecognized non-employee compensation is based on the fair value of the non-vested options as of June 30, 2016 . The fair value of options granted to employees is estimated on the grant date using the Black-Scholes option valuation model. This valuation model requires us to make assumptions and judgments about the variables used in the calculation, including the expected term (the period of time that the options granted are expected to be outstanding), the volatility of our common stock, a risk-free interest rate, and expected dividends. To the extent actual forfeitures differ from the estimates, the difference will be recorded as a cumulative adjustment in the period estimates are revised. No compensation cost is recorded for options that do not vest. We use the simplified calculation of expected life described in the SEC’s Staff Accounting Bulletin No. 107, Share-Based Payment , and volatility is based on an average of the historical volatilities of the common stock of three entities with characteristics similar to those of the Company. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. We use an expected dividend yield of zero, as we do not anticipate paying any dividends in the foreseeable future. Expected forfeitures are assumed to be zero due to the small number of plan participants and the plan design which has monthly vesting after an initial cliff vesting period. The following table presents the weighted-average assumptions used to estimate the fair value of options granted to employees during the periods presented: Three Months Ended June 30, Six Months Ended June 30, 2015 2015 Volatility 58.83 % 63.89 % Risk free interest rate 1.61 % 1.65 % Dividend yield 0.00 % 0.00 % Term (years) 5.99 6.15 Weighted-average fair value of options granted during the period 5.71 5.77 In May 2014, we issued 200,000 options to our Director, Raju Chaganti, with an exercise price of $15.89 .

Equity [Abstract] | |
Warrants | Warrants We have issued certain warrants which contain an exercise price adjustment feature in the event we issue additional equity instruments at a price lower than the exercise price of the warrant. The warrants are described herein as derivative warrants. As of June 30, 2016 all derivative warrants have either expired or have been exercised. On May 25, 2016, we issued 1,357,301 warrants to purchase shares of our common stock as part of our 2016 Offering. Subject to certain ownership limitations, the warrants will be initially exercisable commencing six months from the issuance date at an exercise price equal to $2.25 per share of common stock. The warrants are exercisable for five years from the initial exercise date. The following table summarizes the warrant activity for the six months ended June 30, 2016 (in thousands, except exercise price): Issued With / For Exercise Warrants 2016 Warrants Issued 2016 Warrants Expired Warrants Outstanding June 30, 2016 Non-Derivative Warrants: Financing $ 10.00 243 — — 243 Financing 15.00 436 — — 436 Debt guarantee 15.00 233 — (87 ) 146 Consulting 10.00 10 — (10 ) — 2015 Offering 5.00 3,450 — — 3,450 2016 Offering 2.25 — 1,357 — 1,357 Total non-derivative warrants $ 5.59 B 4,372 1,357 (97 ) 5,632 Derivative Warrants: Financing 4.00 A 60 — (60 ) — Total derivative warrants — B 60 — (60 ) — Total $ 5.59 B 4,432 1,357 (157 ) 5,632 A These warrants were subject to fair value accounting and contained an exercise price adjustment feature.

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The Fair Value Measurements and Disclosures Topic of the FASB Accounting Standards Codification requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, the Topic establishes a fair value hierarchy for valuation inputs that give the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that we have the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect our own assumptions about the assumptions that market participants would use in pricing an asset or liability. The following table summarizes the financial liabilities measured at fair value on a recurring basis segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value (in thousands): June 30, 2016 Total Quoted Prices in Significant Other Significant Notes payable $ 165 $ — $ — $ 165 December 31, 2015 Total Quoted Prices in Significant Other Significant Warrant liability $ 17 $ — $ — $ 17 Notes payable 266 — — 266 $ 283 $ — $ — $ 283 The ultimate payment to VenturEast will be the value of 84,278 shares of common stock at the time of payment. The value of the note payable to VenturEast was determined using the fair value of our common stock less a discount for credit risk. During the three and six months ended June 30, 2016 , we recognized a gain of approximately $67,000 and $101,000 , respectively, due to the change in value of the note. During the three and six months ended June 30, 2016 , we recognized a gain of approximately $17,000 due to the expiration of all remaining warrants underlying the warrant liability. Realized and unrealized gains and losses related to the change in fair value of the VenturEast note and warrant liability are included in other income (expense) on the Consolidated Statement of Operations. The following table summarizes the activity of the notes payable to VenturEast and the warrant liability, which were measured at fair value using Level 3 inputs (in thousands): Note Payable Warrant to VenturEast Liability Fair value at December 31, 2015 $ 266 $ 17 Change in fair value (101 ) (17 ) Fair value at June 30, 2016 $ 165 $ — |

Equity Method Investments and Joint Ventures [Abstract] | |
Joint Venture Agreement | Joint Venture Agreement In November 2011 , we entered into an affiliation agreement with the Mayo Foundation for Medical Education and Research (“Mayo”), subsequently amended. Under the agreement, we formed a joint venture with Mayo in May 2013 to focus on developing oncology diagnostic services and tests utilizing next generation sequencing. The joint venture is a limited liability company, with each party initially holding fifty percent of the issued and outstanding membership interests of the new entity (the “JV”). In exchange for our membership interest in the JV, we made an initial capital contribution of $1.0 million in October 2013. In addition, we issued 10,000 shares of our common stock to Mayo pursuant to our affiliation agreement and recorded an expense of approximately $175,000 . We also recorded additional expense of approximately $231,000 during the fourth quarter of 2013 related to shares issued to Mayo in November 2011 as the JV achieved certain performance milestones. In the third quarter of 2014, we made an additional $1.0 million capital contribution. The agreement also requires aggregate total capital contributions by us of up to an additional $4.0 million . We may make capital contributions up to $1.0 million later in 2016. The timing of the remaining installments is subject to the JV's achievement of certain operational milestones agreed upon by the board of governors of the JV. In exchange for its membership interest, Mayo’s capital contribution takes the form of cash, staff, services, hardware and software resources, laboratory space and instrumentation, the fair market value of which will be approximately equal to $6.0 million . Mayo’s continued contribution will also be conditioned upon the JV’s achievement of certain milestones. Our share of the JV’s net loss was approximately $ 15,000 and $ 198,000 for the three months ended June 30, 2016 and 2015 , respectively, and approximately $27,000 and $ 405,000 for the six months ended June 30, 2016 and 2015 , respectively, and is included in research and development expense on the Consolidated Statement of Operations. We have a net receivable due from the JV of approximately $10,000 at June 30, 2016 , which is included in other current assets in the Consolidated Balance Sheets. The joint venture is considered a variable interest entity under ASC 810-10, but we are not the primary beneficiary as we do not have the power to direct the activities of the JV that most significantly impact its performance. Our evaluation of ability to impact performance is based on our equal board membership and voting rights and day-to-day management functions which are performed by the Mayo personnel. |

Related Party Transactions | Related Party Transactions John Pappajohn, our Chairman of the Board of Directors and stockholder, has 145,778 warrants outstanding at $15.00 per share at June 30, 2016 , granted in consideration for personally guaranteeing our revolving line of credit through March 31, 2014. Mr. Pappajohn also loaned money to us prior to our IPO and was granted warrants in consideration. At June 30, 2016 , Mr. Pappajohn retained 436,079 of these warrants at $15.00 per share. In January 2014, the Board of Directors appointed Mr. Pappajohn to serve as the Chairman of the Board. As compensation for serving as Chairman of the Board, the Company pays Mr. Pappajohn $100,000 per year and granted to Mr. Pappajohn 25,000 restricted shares of the Company’s common stock and options to purchase an aggregate of 100,000 shares of the Company's common stock. In April 2014, we entered into a consulting agreement with Equity Dynamics, Inc. (“EDI”), an entity controlled by Mr. Pappajohn, pursuant to which EDI received a monthly fee of $10,000 . Total expenses for the three months ended June 30, 2016 and 2015 were $30,000 , and for the six months ended June 30, 2016 and 2015 , total expenses were $60,000 . As of June 30, 2016 , we owed EDI $0 . On May 25, 2016, Mr. Pappajohn purchased 317,820 shares of common stock and warrants to purchase 158,910 shares of common stock in the 2016 Offering described in Note 6. In 2010, we entered into a three -year consulting agreement with Dr. Chaganti, which was subsequently renewed through December 31, 2016 pursuant to which Dr. Chaganti receives $5,000 per month for providing consulting and technical support services. Pursuant to the terms of the renewed consulting agreement, Dr. Chaganti received an option to purchase 200,000 shares of our common stock at a purchase price of $15.89 per share vesting over a period of four years. Total non-cash stock-based compensation recognized under the consulting agreement for the three months ended June 30, 2016 and 2015 was $9,500 and $98,625 , respectively. Total non-cash stock-based compensation recognized under the consulting agreement for the six months ended June 30, 2016 and 2015 was $25,625 and $161,125 , respectively. Also pursuant to the consulting agreement, Dr. Chaganti assigned to us all rights to any inventions which he may invent during the course of rendering consulting services to us. In exchange for this assignment, if the USPTO issues a patent for an invention on which Dr. Chaganti is listed as an inventor, we are required to pay Dr. Chaganti (i) a one-time payment of $50,000 and (ii) 1% of any net revenues we receive from any licensed sales of the invention. In the first quarter of 2016, we paid Dr. Chaganti $50,000 which was recognized as an expense in fiscal 2015 when one patent was issued. |

Basis of Presentation | The accompanying unaudited condensed financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions for interim reporting as prescribed by the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary to make the financial statements not misleading have been included. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the audited consolidated financial statements as of and for the year ended December 31, 2015 , filed with the Securities and Exchange Commission on March 10, 2016. The consolidated balance sheet as of December 31, 2015 , included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP. Interim financial results are not necessarily indicative of the results that may be expected for any future interim period or for the year ending December 31, 2016 . |
Recent Accounting Pronouncements | In March 2016, the FASB issued ASU 2016-09 “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” This standard requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid in capital pools. The guidance also allows for the employer to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. The guidance is effective in 2017 with early adoption permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and the timing of adoption. |
