In addition to a determination of fetal viability and gestational age, nuchal translucency measurement
, and a check of basic anatomy, this early exam offers a great opportunity to screen for CHDs--the most common congenital anomaly, with an incidence of about 4-13 per 1,000 live births.
Detection of fetal chromosomal anomalies: does nuchal translucency measurement
have added value in the era of non-invasive prenatal testing?
Extremely large nuchal translucency measurement
predicts adverse pregnancy outcome.
Also, NTD's first trimester non-invasive prenatal screening test for Down Syndrome is the only high sensitivity screen that uses the free Beta hCG biomarker, along with PAPP-A and Nuchal Translucency measurement
, in assessing risk for Down syndrome.
Standard aneuploidy screening included assays of first- or second-trimester serum biomarkers with or without fetal nuchal translucency measurement
The examination was carried out by 4 doctors trained and certified in nuchal translucency measurement
. All fetuses were initially scanned transabdominally and transvaginal scans were performed if required to complete anatomic screening.
Screening for Down's syndrome by fetal nuchal translucency measurement
in a general obstetric population.
The First and Second Trimester Evaluation of Risk (FASTER) trial involved about 38,000 pregnant women at 15 centers who underwent combined first-trimester screening with nuchal translucency measurement
and serum testing for the biochemical markers pregnancy-associated plasma protein A (PAPP-A) and free [beta]-HCG.
NEW ORLEANS -- First-trimester aneuploid screening using maternal age, biochemistry, and nuchal translucency measurement
is "possible, accurate, and reliable," and should be more widely adopted, Dr.
