Average-Risk Screening Guidelines Expand Coverage Pathways
Major obstetric and genetics professional societies are increasingly recommending cell-free fetal DNA testing as a first-line screening option for average-risk pregnancies, moving guidance away from high-risk-only eligibility toward broader population-level screening comparable to how the technology was originally validated only in higher-risk populations a decade earlier. Natera and LabCorp have both expanded average-risk validation studies since 2023, targeting payers that want population-level evidence before extending broad screening coverage. Smaller laboratories are following more slowly, constrained by the validation investment required to support guideline inclusion, but coverage is broadening steadily each year across major developed healthcare markets.
Market Impact: Adds 6% annual eligible population
