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
Ductus venosus studies in fetuses at high risk for chromosomal or heart abnormalities: relationship with nuchal translucency measurement
and fetal outcome.
The examination was carried out by 4 doctors trained and certified in nuchal translucency measurement
Abnormal first-trimester Doppler findings also appear to predict Down syndrome and other adverse outcomes independently of a normal nuchal translucency measurement
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.
When Integrated screening and Sequential screening test results include a fetal ultrasound nuchal translucency measurement
, the highest Down syndrome detection rates are achieved and fewer false positives are experienced than with current first- or second-trimester screening.
Ductus venosus studies in foetuses at high risk for chromosomal or heart abnormalities: relationship with nuchal translucency measurement
and foetal outcome.
Limitations of using first-trimester nuchal translucency measurement
in routine screening for major congenital heart defects.
