The InVisionFirst®-Lung liquid biopsy test is a 37-gene next-generation sequencing assay performed on cell-free circulating tumor DNA in peripheral blood to detect oncogenic driver mutations and therapy targets in non-small cell lung cancer (NSCLC). This assay demonstrated 98% concordance with tissue in clinical validation. Testing is performed by Inivata.

InVisionFirst®-Lung Liquid Biopsy enables discovery of actionable mutations in patients with advanced NSCLC at diagnosis or progression when results are needed more quickly than they can be obtained from tissue testing, or tissue is insufficient, unavailable, or not practical to obtain. Biomarker coverage includes oncogenic drivers and prognostic markers as recommended by current guidelines and literature. Positive results are quantified and delivered in an easy-to-read report annotating clinical trial opportunities, therapies approved in advanced NSCLC and in other indications, and associations with therapy resistance. Tissue testing is recommended over liquid biopsy when possible.
