Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal The Company is involved in various claims and litigation matters from time to time in the ordinary course of business. Management believes that all such current legal actions, in the aggregate, will not have a material adverse effect on the Company. The Company also maintains insurance, including coverage for product liability claims, in amounts that management believes are appropriate given the nature of its business. At June 30, 2015 and December 31, 2014, the Company had $0.3 million accrued as a liability for various legal matters where the Company deemed the liability probable and estimable. Licensing Arrangements The Company has entered into various other licensing and royalty agreements, which largely require payments based on specified product sales as well as the achievement of specified milestones. The Company had royalty and license expenses relating to those agreements of approximately $0.2 million for the three months ended June 30, 2015 and 2014. The Company had royalty and license expenses relating to those agreements of approximately $0.4 million and $0.5 million for the six months ended June 30, 2015 and 2014, respectively. Research and Development Agreements The Company has entered into various research and development agreements that provide it with rights to develop, manufacture and market products using the intellectual property and technology of its collaborative partners. Under the terms of certain of these agreements, the Company is required to make periodic payments based on achievement of certain milestones or resource expenditures. These milestones generally include achievement of prototype assays, validation lots and clinical trials. At June 30, 2015 and December 31, 2014, total future commitments under the terms of these agreements are estimated at $2.4 million and $4.3 million, respectively. The commitments will fluctuate as we agree to new phases of development under the existing arrangements. Contingent Consideration In conjunction with the acquisition of BioHelix Corporation (“BioHelix”) in May 2013, the Company agreed to contingent consideration ranging from $5.0 million to $13.0 million upon achievement of certain research and development milestones and revenue targets through 2018. At December 31, 2014, all research and development milestones had been achieved and all payments related to research and development milestones had been disbursed. No payments related to the royalty revenue earn-out were disbursed during the three months ended June 30, 2015 and 2014. Payments of $0.1 million and $49,000 related to the revenue royalty earn-out were disbursed during the six months ended June 30, 2015 and 2014, respectively. As of June 30, 2015, the current portion of the contingent consideration is $0.6 million and the non-current portion of the contingent consideration is $4.9 million. The fair value of the remaining contingent consideration related to the revenue royalty earn-out to be settled in cash is estimated based on the Monte Carlo Simulation Model. In August 2013, the Company completed a business combination accomplished by acquiring the assets of AnDiaTec GmbH & Co. KG (“AnDiaTec”), a privately-held, diagnostics company, based in Germany. The Company agreed to contingent consideration of up to €0.5 million ($0.6 million based on the June 30, 2015 currency conversion rate) upon achievement of certain revenue targets through 2018. As of June 30, 2015, the current portion of the contingent consideration is $25,000 and the non-current portion of the contingent consideration is $0.1 million, based on the Monte Carlo Simulation Model. In addition, the Company agreed to pay the founder of AnDiaTec contingent payments of up to €3.0 million ($3.4 million based on the June 30, 2015 currency conversion rate) upon achievement of certain research and development milestones, subject to continued employment. The Company paid $0.5 million for the achievement of agreed upon research and development milestones during the three months ended June 30, 2015 and nothing during the three months ended June 30, 2014. The Company paid $0.9 million and $0.3 million for the achievement of agreed upon research and development milestones during the six months ended June 30, 2015 and 2014, respectively.
