BillionToOne's mission is to make prenatal testing safe and affordable for every expecting mother. More than 3,000,000 babies are born with serious genetic defects in the world every year. BillionToOne's novel technology can detect even single-gene disorders such as thalassemia through a simple blood test. We are replacing amniocentesis, an invasive and risky procedure that has a high miscarriage risk, with a safe and affordable blood test, starting with developing countries.
