NT cannot determine the sex of the fetus. NT refers to the thickness of the nuchal translucency and is a test used to determine whether the child has chromosomal abnormalities, and has nothing to do with the sex of the fetus.
The NT test is also called nuchal translucency test and the result of the test cannot determine the sex of the fetus. It is used to measure the thickness of the nuchal translucency to determine the presence of chromosomal or structural abnormalities in the fetus, and is usually performed between 11 and 13+6 weeks of pregnancy.
When the NT thickness is greater than 3 millimeters, there is a 90 percent chance that the fetus is normal. If the NT value is greater than 6 millimeters, there is a 90 percent chance that the fetus is abnormal, and the greater the NT value, the greater the likelihood that the fetus is abnormal.
The larger the NT value, the more likely it is that the fetus is abnormal. The NT value cannot determine the sex of the fetus, and non-medical identification of the sex of the fetus is illegal in China.
