Is NT a must-check? Is NT important?

The NT test is something that every pregnant woman needs to do during pregnancy. This test can help us rule out congenital mental retardation and Down syndrome. It needs to be done at 12 weeks of pregnancy, so pregnant women should do the NT test at a reasonable time. When pregnant women undergo NT examination, they need to choose the thickest neck skin of the fetus for examination, and pregnant women should pay attention to the precautions of the examination.

Is it necessary to do NT test during pregnancy?

1. It is necessary to do NT examination during pregnancy, which can effectively rule out fetal malformations. The NT test is actually a B-ultrasound test, which uses ultrasound to scan the fluid below the fetus's neck and measure its thickness. This data is used to evaluate the risk of Down syndrome. It is an early Down syndrome screening.

2. The detection rate of NT examination is as high as 80%. If combined with the later Down syndrome screening, the detection rate will increase to 85%. Because one of the symptoms of Down syndrome is the lack of nasal bones, the detection rate will increase to 90% if the side of the fetus is scanned.

What should I pay attention to when doing NT examination?

1. The best time for nt examination is between 11 weeks and 13 weeks. Before 11 weeks, it is difficult for the machine to scan the thickness of the nuchal translucency. After 14 weeks, too much fluid will be absorbed by the fetal lymphatic system.

2. The NT is an abdominal B-ultrasound, so you should wear appropriate clothes, preferably separate clothes, so as not to be embarrassed.

3. You don’t need to be on an empty stomach or hold your urine when doing NT. If you do it together with creating a profile, you can do it on an empty stomach. The body does not need any special preparation.

I believe that everyone should now understand the necessity of NT examination. NT examination can effectively rule out fetal malformations for pregnant friends during pregnancy, so its role cannot be ignored. Pregnant women must attach importance to this examination and be adequately prepared for it, and must pay attention to controlling the time of the NT examination between 11 and 13 weeks.
