Effect of first-trimester nuchal translucency on second-trimester maternal serum biochemical screening for Down's syndrome

Nuchal translucency measurement in first trimester Down syndrome screening.

(1) Approximately three in every four fetuses with Down syndrome have increased nuchal translucency (NT), which is a larger than normal build-up of fluid at the back of the neck. (2) The ultrasound measurement of NT between 11 and 14 weeks' gestation, in combination with the mother's age and the levels of placental biochemical markers in her blood, can be used to detect approximately 84% of fet...
