Normal range of nt value at 13 weeks

Pregnant women need to go to the hospital regularly for many tests. These tests can determine whether the fetus is normal. Due to the different months of pregnancy, the tests that need to be done are also different, so there are many issues that are not well understood. Then, what is the normal range of the NT value at 13 weeks is a question that pregnant women are very concerned about.

13 weeks nt value is within normal range

At 13 weeks of pregnancy, if the nt value test result is less than 3mm, it means it is within the normal range. During pregnancy, you must maintain adequate sleep and not exercise excessively, otherwise it may harm the fetus. You must go to the hospital regularly for various prenatal checkups. You should also pay attention to your diet and try not to eat irritating foods.

Many parents are very curious about the gender of the fetus. Although medicine is relatively developed nowadays and there are many ways to determine the gender of the fetus, it is impossible to determine the gender of the fetus using methods such as NT examination. It can only screen whether the fetus has congenital malformations. This test is very important and can make a diagnosis of fetal sex chromosome diseases in the early stages.

If fetal malformations are ruled out in the early stages of pregnancy, parents can rest assured. If the nt value exceeds 3mm during the examination, it means that the baby's growth and development is not good and further examination is generally required. You should have a certain understanding of the normal range of NT values. If you find any abnormalities in the future, you don't have to strictly follow the doctor's advice.

What is NT test?

nt (nuchal translucency), that is, the thickness of the neck membrane, refers to the maximum thickness between the skin and the subcutaneous soft tissue in the sagittal cross-section of the fetal cervical vertebrae. The inspection method is as follows:

1. The NT test, also known as the nuchal translucency scanner, uses B-ultrasound to accurately measure the location of the thickest echo-free transparent layer of the subcutaneous tissue in the fetus's neck. It is a way to assess whether the fetus is likely to suffer from Down syndrome. It is a screening method.

2. The NT test is different from diagnostic tests such as chorionic villus aspiration biopsy or amniocentesis. They can provide a clear diagnosis, but the NT test can only remind of the risk.
