BillionToOne Unity Prenatal Screen

BillionToOne has commercially launched its Unity prenatal screening assay. According to BillionToOne, the assay is powered by its molecular counting technology and is the only prenatal screen that tests cell-free fetal DNA for cystic fibrosis, spinal muscular atrophy, and sickle cell disease using only one tube of the mother's blood. The firm said it will make the test available at select clinics through its early access program, with plans for a broader commercial launch later this year.
