BillionToOne provides molecular diagnostic testing for prenatal screening and cancer monitoring. Its QCT technology detects and measures DNA variations at a single base-pair level, enabling precise analysis across the three billion DNA letters. The main products, Northstar Select and Northstar Response, are tests that help doctors choose the best first-line therapy and track how well treatment is working, respectively. The company markets these services to healthcare providers who perform the tests and use the results to guide patient care. Unlike some rivals, BillionToOne emphasizes high-resolution DNA assessment and scalable diagnostic services through provider partnerships, aiming to improve accuracy, speed, and access. Its mission is to make molecular testing more accurate, efficient, and accessible to all, driven by growth, equality, and teamwork.
