Who is the test tube baby NT suitable for?
Test tube baby NT (Nuchal Translucency) is a method for early screening of fetal genetic diseases. The risk of chromosomal abnormalities in the fetus is assessed through the thickness of the fetal neck detected by B-ultrasound combined with the blood test results of pregnant women. Although IVF NT has been widely used worldwide, not all people are suitable for this screening. This article will elaborate on the applicable population of IVF NT from four aspects: pregnant women's age, genetic disease risk, prenatal examination results and medical conditions.

Age of pregnant women
The age of pregnant women is one of the important factors to judge the applicability of IVF NT. Generally speaking, pregnant women aged 35 and above are more likely to have chromosomal abnormalities, such as Down syndrome. Therefore, for pregnant women aged 35 and above, IVF NT is a very necessary screening method. For pregnant women under the age of 35, although the probability of chromosomal abnormalities is relatively low, it is still necessary to eliminate risks through IVF NT to ensure the health of embryos.
In addition, in some special cases, the age of pregnant women is not the only consideration. For example, for women who have had multiple pregnancy failures or abnormal pregnancy, even if they are younger, they may need to carry out IVF NT to assess the fetal development.
Risk of genetic diseases
Some populations have a high risk of genetic diseases, which is also one of the suitable populations for IVF NT. For example, if both the husband and wife are carriers of genetic diseases, or a child has been born with chromosomal abnormalities, in vitro NT can more accurately assess the health of the embryo and avoid the risk of chromosomal abnormalities again.
Test tube baby NT is also an important screening method for pregnant women with known genetic diseases in their families. By detecting the chromosome of the fetus, we can find out whether there is a family genetic disease as soon as possible, so that parents can make more intelligent decisions.
Pre pregnancy examination results
The results of pre pregnancy examination are also important basis for deciding whether to carry out test tube baby NT. During the genetic counseling before pregnancy, the doctor will evaluate the necessity for couples to accept IVF NT according to their genetic status and family history of certain diseases.
In addition, the blood test results of pregnant women will also affect the applicability of IVF NT. According to the fetal free DNA in the blood and the genetic condition of the pregnant woman, doctors can predict the risk of chromosomal abnormalities in the fetus, providing a basis for whether to carry out IVF NT.
Medical conditions
The last factor is medical conditions. IVF NT needs to be carried out in hospitals with relevant technology and equipment, so as to ensure the accuracy and safety of screening. Therefore, only those hospitals with IVF NT technology can provide corresponding services. When choosing IVF NT, couples need to ensure that the selected hospital has a good reputation and a professional medical team.
In conclusion, IVF NT is applicable to older pregnant women, couples with genetic disease risk, couples with abnormal prenatal examination results, and couples who choose hospitals with relevant technologies and equipment. Through the screening of test tube baby NT, we can know the health status of the fetus as soon as possible, make corresponding decisions in advance, and ensure the healthy development of the embryo.
