The Nuchal Translucency (NT) Calculator is a powerful tool used during the first trimester of pregnancy to assess the risk of chromosomal abnormalities, such as Down syndrome, in the developing fetus.
Screening by NT can detect about 80% of fetuses with trisomy 21 and other major aneuploides for a false positive rate of 5%. The combination of NT and maternal serum free β-hCG and PAPP-A improves the detection to 90%.
The first trimester screening test (FTS) is blood work, and the nuchal translucency test is specialized imaging of the fetus using ultrasound. When the two tests are performed together, the combined data can help assess the risk of certain genetic conditions, but it cannot diagnose them.
It involves a blood test and measuring the fluid at the back of the baby's neck (nuchal translucency) with an ultrasound scan. This is sometimes called a nuchal translucency scan. The nuchal translucency measurement can be taken during the dating scan.
