How long does the NT test take?

Whether the baby is born healthy or not is closely related to many details during pregnancy. In order to make the future baby healthier, pregnant women must actively go for prenatal check-ups so that they can promptly detect abnormalities in the fetus and take timely measures to solve them. The NT test is one of many prenatal check-up items. How long does the whole process of the NT test take?

The NT test can also be regarded as a fetal malformation screening test. It uses the B-ultrasound method to test the thickness of the transparent zone on the fetal neck to determine whether the fetal growth and development is normal. The length of the examination process has a lot to do with the position of the fetus. If the fetus is in a suitable position and the zona pellucida can be easily detected, the procedure can be completed in about ten minutes.

But if the fetus is in the wrong position, the zona pellucida cannot be seen. It is necessary to stimulate fetal activity until the zona pellucida can be detected, and then the fetus will be born later. Some pregnant women need to toss and turn several times, trying various methods to stimulate fetal activity. Such situations are very rare, and most pregnant women can still pass it in one go.

The timing of the NT test should be mastered. It is best to conduct the test at 12 weeks of pregnancy. Because the zona pellucida exists for a very short time, it only appears at 10 weeks of pregnancy and disappears at 14 weeks. If you don't manage your time well, you may miss the opportunity to check this item.

The time it takes for each hospital to issue the NT test report is different. Generally, the results can be obtained on the same day. Nt testing is used to diagnose fetal sex chromosome disorders and detect fetal development abnormalities caused by various reasons at an early stage of pregnancy. Generally speaking, it is recommended to be between 11 and 13 weeks of pregnancy. Beyond 14 weeks, the results are inaccurate.
