Screening completed at the 12+3 gestational week, which included fetal nuchal translucency measurement
, maternal serum pregnancy-associated plasma protein A levels, and free beta-human chorionic gonadotropin levels, showed no increased risk for trisomies 21, 18, and 13.
Abnormal first-trimester Doppler findings also appear to predict Down syndrome and other adverse outcomes independently of a normal nuchal translucency measurement
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.
Patients found to be screen positive for possible chromosome conditions (such as Down syndrome or trisomy 18), or have an increased nuchal translucency measurement
, are referred for other services that include genetic counseling, ultrasound, amniocentesis and chorionic villus sampling (CVS).
First-trimester nuchal translucency measurement
and echocardiography at 16 to 18 weeks of gestation in prenatal detection for trisomy 18.
MIAMI BEACH -- A nuchal translucency measurement
of at least 4 mm identified during prenatal ultrasound screening for aneuploidy warrants immediate consideration of chorionic villus sampling, Dr.
First trimester trisomy screening: Nuchal translucency measurement
training and quality assurance to correct and unify technique.
NT/freeBeta/PAPP-A, referred to as Early Screen(R), is available to all pregnant patients throughout the USA and is provided by sonographers and physicians who have Fetal Medicine Foundation special training and certificates for nuchal translucency measurement
5 percent false positive rate with traditional combined first trimester screening with serum markers and nuchal translucency measurement
We now know, without doubt, that first-trimester screening that combines maternal serum free [beta]-human chorionic gonadotropin and pregnancy-associated plasma protein-A with fetal nuchal translucency measurement
is better than second-trimester screening, and we must embrace this new knowledge.
Blood samples will be collected between 10 and 14 weeks, and those receiving the standard first-trimester screening will also receive a nuchal translucency measurement
performed via ultrasound.
