Prenatal microarray testing revenues in the second quarter and first half of 2013 were $836,000 and $1.7 million, respectively, as compared to $331,000 and $645,000 in the 2012 periods.

Growth in our microarray volumes, positive coverage decisions at multiple third-party payors and the recently announced partnership with Sequenom provides evidence of that progress. In addition, we are driving the fastest growth in the most important and highest margin segment of our business – prenatal microarray testing."
