A woman whose fetus' nuchal translucency is greater than the 95th percentile is also at. The nuchal translucency test (also called the NT scan) uses ultrasound to assess your developing baby's risk of having Down syndrome (DS) and some other chromosomal abnormalities, as well as major congenital heart problems. When the results of this blood test are combined with the results from the first trimester blood test and nuchal translucency ultrasound, the detection rate for Down syndrome increases.

Although nuchal translucency measurement alone is a good detector of Down syndrome, trials have shown. It helps doctors determine if a baby is statistically more likely. The nuchal translucency measurement needs to be performed by experienced sonographers and should be obtained between 10 and 13 weeks 6 days of gestation which is equivalent to a crown-rump length between 38 and 84 mm. 2 mm to 1. All fetuses develop a measurable nuchal translucency at some point in the first trimester. If your scan is done along your abdomen — transabdominally — you will be asked to drink a few. The NT.
