Performance of a cell‐free DNA prenatal screening test, choice of prenatal procedure, and chromosome conditions identified during pregnancy after low‐risk cell‐free DNA screening

Abstract excerpt

OBJECTIVES: To evaluate the performance of cell-free DNA (cfDNA) screening for common fetal aneuploidies, choice of prenatal procedure, and chromosome conditions identified during pregnancy after low-risk cfDNA screening. METHOD: A single-center prenatal cfDNA screening test was employed to detect trisomies 21, 18, and 13 (T21, T18, T13) and sex chromosome aneuploidies (SCAs). Test performance, choice of prenatal...
