The Utility of Nuchal Translucency Screening in the Era of Cell-Free Fetal DNA Testing
In this retrospective cohort study of 1,901 pregnant women between 11 weeks and 13 weeks six days of gestation who had a nuchal translucency (NT) screening for fetal aneuploidies and demonstrated NT measurements > 95th percentile, 47% of fetuses (894/1,901) had an NT between the 95th and 99th percentile and 53% (1,007/1,901) had an NT ≥ the 99th percentile. In addition, of the 43% of fetuses (814/1,901) with at least one abnormality (structural or genetic), 34% (279/814) would have been missed in the first trimester if only cell-free deoxyribonucleic acid was used for prenatal genetic screening.
