Use

The Labcorp Plasma Focus test is a Next Generation Sequencing-based laboratory-developed test (LDT) for the detection of genomic sequence mutations in 33 clinically actionable or relevant genes, including amplifications in eight genes, translocations associated with five genes and microsatellite instability (MSI) using plasma derived cell DNA (cfDNA). The test is intended to be used by qualified health care professionals in accordance with professional oncology guidelines for patients with advanced stage or metastatic non small cell lung cancer, colorectal cancer, breast cancer, esophageal cancer, gastroesophageal junction cancer, gastric cancer or melanoma. Test results are not prescriptive for the use of any specific therapeutic product.
