Clinical Diagnostics Testing

About Us

Granger Genetics

Granger Genetics is located in Richmond , Virginia. The company evolved after an asset purchase in 2016. The original company became independently owned in 2011 from Bostwick Labs and continued an existing model of “everything to everybody” providing clinical testing services and a strong contract research organization. Senior management determined that the company’s “best self” would be the focus on clinical laboratory testing and molecular biology research. Granger Genetics evolved out of this restructuring, giving the company a better focus on its services, a more robust research program and fresh forward thinking leadership to drive the company with new diagnostic products and services. Here at Granger in our clinical laboratories, our #1 goal and commitment is to patient safety and quality. We are a CLIA certified laboratory to perform high complexity diagnostic testing. We are constantly seeking solutions to specific medical concerns brought to our attention. Providing the medical community with personalized, quality testing options is what sets Granger Genetics apart from the competition. We no longer want to be “everything to everybody”- we want to be your choice for your patients in personalized medicine.
