NT examination is a type of examination that can exclude abnormalities to a certain extent, and it is a very important item in prenatal examination. If there are no major problems with this examination, it proves that the baby's physical health is more likely. In order to detect and solve problems as early as possible, what does it mean to pass NT smoothly?
1. NT smooth means that the baby's deformity may be small. This prenatal examination is the first examination to exclude abnormalities in the fetus. If its measurement value is less than three millimeters, it is generally normal; But if it exceeds three millimeters, further inspection is needed. This is an important indicator of whether the fetal chromosomes are abnormal.
2. The best time for NT inspection. The best time for this examination is generally within 11 to 14 weeks of pregnancy, mainly because the fetus is still too small before 11 weeks, and it is not possible to observe the posterior nuchal translucency of the fetus. But after 14 weeks, the fetus will gradually develop again, which will greatly affect the test results.
3. NT is high-risk. If such a situation occurs, pregnant women must take it seriously and calm down. This is just a reminder, and no matter what kind of examination it is, there is no 100% certainty. This prompt only suggests that the baby may have a chromosomal disease, but doctors usually confirm it through other means, such as non-invasive genetic testing. If there are no problems with other tests, then the baby is still healthy.
