After pregnancy, women need to undergo an NT related examination between 11 and 13 weeks. This examination is mainly aimed at checking whether the fetus has some congenital abnormalities. If the NT value exceeds the standard, it is considered abnormal. Is there anything normal after NT 2.9mm?
During pregnancy, if the NT value exceeds the standard value during examination, it indicates that the fetus may have some congenital chromosomal diseases and heart problems. As long as the thickness of nt does not exceed 3mm, it is considered a normal value, and for values exceeding 3mm, the higher the value, the greater the risk of fetal illness.
In order to ensure the accuracy of the nt value test data, women must grasp the correct examination time during pregnancy. Early or late examination can lead to abnormal values. The best time for examination is around 12 weeks of pregnancy, as being too early or too late can affect the accuracy of the examination results.
If the nt value exceeds the standard during the examination process, other examinations should be conducted in a timely manner to clearly rule out whether the fetus has any health problems. Generally, amniocentesis and non-invasive DNA testing are required to check if the fetus has some congenital diseases.
