Noninvasive Prenatal Testing for Whole Fetal Chromosomal Aneuploidies: A Multicenter Prospective Cohort Trial in Taiwan.


Department of Obstetrics and Gynaecology, Chang Gung Memorial Hospital at Linkou, College of Medicine, Chang Gung University, Taoyuan, Taiwan.


Objective: To evaluate the performance of noninvasive prenatal testing for all fetal chromosomal aneuploidies in an extremely high-risk group undergoing first trimester combined Down syndrome screening. Method: A multicenter cohort prospective study in Taiwan was performed between June and December 2012. Maternal plasma was collected and shotgun massive parallel sequencing was performed on each fetal chromosome. 201 Taiwanese pregnant women at >12 weeks' gestation from 11 medical centers were enrolled in this trial. The extremely high-risk group was defined as a Down syndrome risk cutoff >1:30 or nuchal translucency >3.0 mm (n = 100), while the low-risk group was defined as a Down syndrome cutoff <1:1 100="" 11="" 13="" 16="" 18="" 1="" 2013="" 21="" 3="" 45="" 47="" 8="" 96="" abnormalities="" ag="" also="" amniocentesis="" amount="" an="" and="" aneuploidies="" aneuploidy="" applied="" autosomal="" basel.="" be="" because="" birth="" can="" case="" cases="" chromosomal="" chromosome="" conclusions:="" confirmation="" detected="" detection="" efficiently="" extremely="" false-positive="" fetus="" first="" for="" gravidas="" group="" high-="" high-risk="" in="" insufficient="" karger="" low-risk="" maternal="" n="27/100" no="" noninvasive="" of="" one="" or="" outcome="" overall="" p="" performed="" plasma="" populations.="" prenatal="" prenatally="" rate="" recorded.="" results:="" s.="" sex="" shows="" specificity="100%)." study.="" syndrome.="" taiwan="" testing="" that="" the="" there="" this="" trial="" trisomy="" turner="" was="" were="" whole="" with="">
