How long does it take to do nt during pregnancy

With the gradual development of medical technology and the awareness of eugenics being accepted by more and more young people, modern people will undergo many important tests during pregnancy, one of which is called NT. So what exactly does this NT test check? Generally, at what stage of pregnancy is it appropriate to do NT? Friends who are interested can follow the editor to discuss.

How long is the pregnancy suitable for NT?

Nuchal translucency scanning is usually performed between 11 and 14 weeks of pregnancy. It is technically impossible to perform an NT test before 11 weeks because the fetus is still very small. After 14 weeks, the water stored in the fetus's subcutaneous tissue may be absorbed by the developing lymphatic system, making it impossible to obtain accurate test data. Therefore, pregnant women need to go to the hospital for NT examination within 11-14 weeks of pregnancy. Generally, a nuchal translucency scanner can be performed in a tertiary hospital or a large specialized gynecological hospital.

What does nt check

Babies with Down syndrome also have water retention in the subcutaneous tissue, so the skin on the back of the neck will be thicker. If the NT test shows that the thickness of the fetal neck skin exceeds the standard value, it may be related to abnormalities in the fetal chromosomal karyotype and other anatomical abnormalities. The thicker the NT, the greater the chance of fetal anatomical abnormalities and chromosomal abnormalities.

In addition to detecting the risk of chromosomal abnormalities, thickening of the fetal nuchal translucency is also related to congenital heart disease.

If the NT test result exceeds the index value range, it is recommended that the pregnant woman conduct a subsequent fetal abnormality examination to further determine the risk of fetal abnormalities so that countermeasures can be taken as soon as possible.

It turns out that this mysterious NT test is a screening for Down syndrome, which is very important for pregnant women themselves and even the entire society. At present, only some qualified hospitals can perform this inspection. It is precisely because of the advanced modern medical technology that the occurrence of many congenital diseases has been greatly reduced, which is of great significance for improving the quality of the population. ��Actual effect.

Under normal circumstances, from pregnancy to delivery, women's breast size may increase by more than 15-20 cm due to the influence of estrogen. Therefore, it is necessary to change underwear appropriately according to the changes in the breasts during pregnancy, and do a good job of breast care and maintenance. This will help promote milk secretion and allow breastfeeding during delivery. I hope that will be helpful.
