Many new mothers who have just become pregnant are not clear about the specific procedures for pregnancy and do not know what tests pregnant women should undergo. However, pregnant women need to undergo various tests and pay attention to many things, including prenatal check ups. So, when should I do the NT test for pregnancy? Next, friends, let's take a look with the editor.
When should I do NT testing during pregnancy
Cervical posterior transparent band scan is usually performed between 11-14 weeks of pregnancy. It is technically difficult to perform NT examination before 11 weeks because the fetus is still too small at this time. After 14 weeks, the subcutaneous fluid in the fetus may be absorbed by the developing lymphatic system, making it impossible to obtain accurate detection data. Therefore, pregnant women need to go to the hospital for NT examination within 11-14 weeks of pregnancy.
Is it necessary to do NT inspection
NT is a method for evaluating whether a fetus may have Down syndrome and is a screening tool. Fetuses with Down syndrome may experience subcutaneous fluid accumulation, resulting in thicker skin behind the neck. If NT detects that the thickness of fetal neck skin exceeds the standard value, it may be related to fetal chromosomal karyotype abnormalities and other structural abnormalities, and the thicker the NT, the higher the probability of fetal structural and chromosomal abnormalities.
When should I do the NT test for pregnancy? Pregnant women should do NT between 11-14 weeks, expectant mothers should remember. At the same time, it is necessary for every pregnant mother to do NT, which is beneficial for the fetus. In addition, there are many tests to be done during pregnancy, and expectant mothers can learn about them in advance. Finally, I wish all expectant mothers and babies good health.
