Evaluation of the Z‐score accuracy of noninvasive prenatal testing for fetal trisomies 13, 18 and 21 at a single center

22 Jan 2021

Abstract excerpt

OBJECTIVE: To assess the correlation between Z-scores of positive noninvasive prenatal testing (NIPT) results and the positive predictive value (PPV) of NIPT. METHODS: Pregnancies with positive NIPT results at Guangzhou Women and Children's Medical Centre between July 2017 and May 2020 were included in this study. Fetal karyotyping or microarray analysis was provided to patients with abnormal NIPT results for...
