Low Fetal Fraction and Birth Weight in Women with Negative First-Trimester Cell-Free DNA Screening

18 Nov 2019

Abstract excerpt

Abstract Objective To determine the association between low fetal fraction and birth weight among women with a negative cell-free DNA (cfDNA) result for common aneuploidies in the first trimester. Study Design This is a retrospective cohort of women who delivered a singleton between July 2016 and June 2018 at a single institution and had normal cfDNA testing in the first trimester. The primary variable of...
