NT examination is a necessary prenatal examination for women during pregnancy, but some first-time mothers may not have much knowledge about this examination because there are many prenatal examination items during pregnancy, and some examinations also need to be performed on an empty stomach. So, do pregnant women need to undergo NT testing on an empty stomach?

1. NT examination is a mandatory prenatal check-up during pregnancy, and pregnant women do not need to go on an empty stomach if they only undergo NT examination. This examination will monitor the thickness of the fetal nuchal translucency through ultrasound to determine the possibility of chromosomal diseases and developmental abnormalities.
2. When measuring, if the thickness of the nuchal translucency of the fetus is less than 2.5 millimeters, it indicates that it is at a normal level. If the measured value is greater than 3 millimeters, it belongs to excessive thickening of the nuchal translucency. Generally, if the measurement value is greater than 2.5 millimeters, it is considered that there is an increased risk of 21-3 body types. Therefore, multiple targeted prenatal examinations should be conducted in the following weeks of pregnancy to determine whether there are high-risk factors.
3. The time for women to undergo NT testing after pregnancy should be between 11-14 weeks, which is the optimal gestational age for testing. Before the examination, it is not necessary to go on an empty stomach, and it is better to go to the hospital for examination after eating, because the activity of the fetus in the uterus will also increase after eating, which can provide better fetal position and clearer observation, which is beneficial for doctors to make more accurate examination results.
