The GeneStrat® Genomic Test is a blood-based series of ddPCR tests for DNA (EGFR, KRAS, BRAF) and multiplexed assays for RNA variants (EML4-ALK, ROS1, RET).  In this report we will update on test and specimen collection kit design considerations, feasibility and product development studies. We will report on post-launch test performance using the included nucleic acid preserving blood collection tubes.
