The Lung Cancer Circulating Tumor DNA Multi-gene Mutation Combined Detection Kit is next-generation sequencing (NGS) based and non-invasive. Enabling highly accurate mutation detection across the most clinically relevant genes associated with lung cancer. The kit allows highly sensitive detection of actionable mutations across the genes from liquid biopsy samples of patients whose tissue samples are inaccessible. It provides a comprehensive molecular profiling of lung cancer for clinicians and researchers.
