Premier Genomics is a CLIA-accredited, CAP-certified clinical laboratory that offers cutting-edge genetic testing.

Partnering with private practices and institutions, we serve physicians and their patients by offering genetic tests and comprehensive reports that give physicians the tools they need to guide patient medical management. We specialize in the areas of Pharmacogenomics, Prenatal/carrier screening, Infectious Disease, Hereditary Cancer and Wellness.

Founded by physicians, we strongly believe that the value of advanced genetic testing lies in actionable, relevant results reporting with medical management guidance, based on publications by international pharmacogenetics expert groups, consortia, or regulatory bodies.
