Fetal fraction in maternal plasma cell-free DNA at 11-13 weeks' gestation: relation to maternal and fetal characteristics.
OBJECTIVE To examine the possible effects of maternal and fetal characteristics on the fetal fraction in maternal plasma cell-free (cf) DNA at 11-13 weeks' gestation and estimate the proportion of pregnancies at high risk of non-invasive prenatal testing (NIPT) failure because the fetal fraction is less than 4%. METHODS In 1949 singleton pregnancies at 11-13 weeks' gestation cf-DNA was extrac...
متن کاملFetal fraction in maternal plasma cell-free DNA at 11-13 weeks' gestation: effect of maternal and fetal factors.
OBJECTIVE It was the aim of this study to examine the possible effects of maternal and fetal characteristics on the fetal fraction in maternal plasma cell-free DNA (cfDNA) at 11-13 weeks' gestation. METHODS In a nested case-control study, cfDNA was extracted from maternal plasma obtained before chorionic villous sampling from 300 euploid, 50 trisomy 21 and 50 trisomy 18 pregnancies at 11-13 w...
متن کاملMaternal thyroid function at 11-13 weeks of gestation in fetal trisomies 21 and 18.
OBJECTIVE To examine the association between maternal serum levels of thyroid stimulating hormone (TSH) and free β-human chorionic gonadotrophin (free β-hCG) in trisomy 21, trisomy 18 and euploid pregnancies at 11-13 weeks and investigate the potential value of TSH in first-trimester screening for aneuploidies. METHODS Maternal serum TSH and free β-hCG levels at 11-13 weeks in 25 trisomy 21 a...
متن کاملTracking embryo implantation using cell-free fetal DNA enriched from maternal circulation at 9 weeks gestation.
Embryo DNA fingerprinting represents an important tool for tracking embryo-specific outcomes after multiple embryo transfer during IVF. The situation in which two embryos are transferred and only one implants represents a unique opportunity for the most well-controlled validation of markers capable of identifying competent and incompetent embryos. Specifically, this design eliminates all patien...
متن کاملFetal RHD genotyping in maternal plasma at 11-13 weeks of gestation.
OBJECTIVE To examine the feasibility of fetal RHD genotyping at 11-13 weeks' gestation from analysis of circulating cell-free fetal DNA (ccffDNA) in the plasma of RhD negative pregnant women using a high-throughput robotic technique. METHODS Stored plasma (0.5 ml) from 591 RhD negative women was used for extraction of ccffDNA by a robotic technique. Real-time quantitative polymerase chain rea...
