Patient's question:
I went with my wife for a prenatal check-up yesterday and found an NT item I didn't understand. Hello, what is the meaning of NT in prenatal examinations for pregnant women?Doctor's answer:
Hello, after pregnancy, an NT detailed examination is usually performed between 11 and 13+6 weeks of gestation. NT is an early screening for Down syndrome, which can preliminarily determine the risk of the fetus having Down syndrome based on the thickness of the nuchal translucency. If the nuchal translucency is greater than 2.5 millimeters, it is important to prepare for the mid-trimester Down syndrome screening. Based on the pregnant woman's height, weight, age, gestational week, and other factors, the risk of the fetus being high-risk for Down syndrome can be estimated.
