BillionToOne study in general-risk pregnancies shows 94.4% sensitivity for Unity cfDNA recessive-condition screen

BillionToOne disclosed publication of a prospective, multi-site prenatal screening study in The Green Journal on Aug. 18, 2026.

• Results were presented as published findings, not as a future conference readout.
• Study outcome supported using a single maternal blood draw to assess fetal risk for inherited conditions in routine, general-risk pregnancies.
• Data indicated the approach reduced missed high-risk pregnancies tied to incomplete partner testing, a key bottleneck in standard carrier screening workflows.
• Publication strengthens the commercial case for Unity Fetal Risk Screen as a primary screen, supporting broader adoption in everyday prenatal care.
