NT examination is an important examination used to evaluate the health of the fetus. The best examination time is 11-13 weeks + 6 days of pregnancy. Let us learn more about the relevant knowledge of NT inspection. Why is the timing of NT examination so important? This is because before 11 weeks of pregnancy, the baby is still too young and it is difficult to accurately measure NT. After 14 weeks, the baby\’s developing lymphatic system will absorb too much fluid, which can lead to inaccurate NT results. Therefore, in order to ensure the accuracy of the inspection results, we need to conduct the NT inspection within the optimal time. However, the judgment of the pregnancy cycle may be interfered by some factors, such as delayed ovulation, irregular menstruation, or misremembering the last menstrual period. In order to avoid the influence of these factors, it is recommended to choose an intermediate period for examination, such as around 12 weeks of pregnancy. This ensures the accuracy of the test results and avoids unnecessary worry and anxiety. NT examination assesses the health status of the fetus by measuring the maximum thickness of the anechoic layer between the skin at the back of the neck and the subcutaneous soft tissue on the sagittal plane at the level of the fetal cervical spine. This test can detect chromosomal disorders and other abnormalities in the fetus early, such as Down syndrome. If NT is thickened, it may be related to chromosomal abnormalities, including trisomy 21, trisomy 18, trisomy 13, etc. Therefore, NT examination is of great significance to protect the health of mothers and infants. Classic saying: \”There is only one kind of heroism in the world, and that is to still love life after recognizing the truth of life.\” – Romain Rolland NT examination is one of the important means to protect the health of mothers and infants. We should attach great importance to it and promptly Check.
