NT is a well-known examination, especially during pregnancy, where pregnant women often hear the name NT. But many people are not very familiar with serological prenatal screening and NT, and cannot figure out what the two specifically refer to. So, is serological prenatal screening NT?
Serological prenatal screening is not NT, it actually refers to Down syndrome screening, which is different from NT testing. Serological prenatal screening mainly tests the blood of pregnant women, including serum tests, in order to calculate the risk factor of Down syndrome in fetuses. And NT only occurs during fetal progress, it belongs to liquid, but it is transparent.
Serological prenatal screening and NT are two different tests, but the main purpose of both tests is to check the incidence of fetal abnormalities. Taking NT examination as an example, once NT shows abnormal thickening, it means that its thickness exceeds the normal range, which is an abnormality and may indicate the presence of Down syndrome in the fetus.
The main purpose of serological prenatal screening examination is to detect the possibility of Down syndrome. Once this abnormality is detected, further amniocentesis can be performed. This examination method mainly involves extracting appropriate amniotic fluid. Jia Ling's examination has a relatively high accuracy rate, which can reach 100%.
