The UNITY Screen test by BillionToOne is a prenatal screening test that uses a blood sample from the mother to assess the risk of the fetus developing severe recessive genetic conditions, such as cystic fibrosis, sickle cell anemia, thalassemias, and spinal muscular atrophy (SMA). This test utilizes cell-free DNA (cfDNA) found in maternal blood to provide insights into the fetus’s genetics.
Children with the most common form of SMA have access to genetic therapy to improve their quality and lifespan. Treatment can begin shortly after birth.
