Pregnancy NT test cost

The NT test is: NT (nuchal translucency), that is, the nuchal translucency, which refers to the maximum thickness between the skin and the subcutaneous soft tissue in the sagittal cross-section of the fetal cervical vertebrae. The NT test, also known as the nuchal translucency scan, is a method that uses B-ultrasound to accurately measure the location of the thickest echo-free transparent layer of the subcutaneous tissue in the fetus's neck to assess whether the fetus is likely to have Down syndrome.

If the NT value of a pregnant woman is found to be outside the normal range during the NT test, further fetal abnormality screening should be carried out, such as amniocentesis or chorionic villus sampling, to determine whether she has Down syndrome or other diseases.

The charges for nuchal translucency scanning vary in different hospitals and regions. Some hospitals require this new item to be a self-paid examination item, and some hospitals can go through the maternity insurance procedure. How much does an NT test cost? Generally speaking, the price of an NT test is around 100-300 yuan. Pregnant women can consult the local hospital clinic for details.

NT test is usually done in a few weeks of pregnancy

The fetus usually undergoes NT examination around 12 weeks. Because the change of nuchal translucency is closely related to the number of weeks of pregnancy, accurate measurement of nuchal translucency is limited to 10-14 weeks of pregnancy. During a normal 10-14 week pregnancy, the thickness of the nuchal translucency increases slightly with the number of weeks of pregnancy. A rough and simple estimation method is that any value less than 2.5 mm is considered normal, and any value greater than 2.5 mm is diagnosed as thickened nuchal translucency. The nuchal translucency disappears after 14 weeks of pregnancy. The thickness of the fetal neck skin can be accurately measured between 14 and 21 weeks of pregnancy, which is also a reasonable indicator value. When the thickness of the neck skin is greater than 6mm, the possibility of chromosomal abnormalities in the fetus should be considered. The positive diagnosis rate is 39-56%.
