Biocept, Inc., a molecular oncology diagnostics company, develops and commercializes proprietary clinical diagnostic laboratory assays designed to identify rare tumor cells and cell-free tumor DNA from blood and cerebrospinal fluid, or CSF in the United States. Its cancer assays provide information to healthcare providers to identify oncogenic alterations that qualify a subset of cancer patients for targeted therapy at diagnosis, progression, and monitoring to identify resistance mechanisms. The company offers assays for solid tumor indications, such as breast cancer, non-small cell lung cancer (NSCLC), gastric cancer, colorectal cancer, prostate cancer, pancreaticobiliary cancer, and ovarian cancer.

The company has a collaboration with CLEARED4 to develop a system for tracking and managing COVID-19 testing requirements and test results for its customers; and with Protean BioDiagnostics, Inc. to research the ability of its Target Selector molecular assay to determine EGFR status in NSCLC patients.
