Will NT be passed through non-invasive

NT is based on B-ultrasound examination of the thickness of the nuchal translucency of the fetus, and is used to eliminate some sex chromosome hereditary diseases. Minimally invasive DNA prenatal non-destructive testing technology involves drawing blood for testing to see if there are any abnormalities in the fetus' sex chromosomes. So if NT is approved, will minimally invasive surgery be approved?

NT is based on minimally invasive surgery. Will it be based on

uncertain

Under normal circumstances, NT will be successful after minimally invasive surgery, but there are also exceptions. And if the pregnant woman and her husband's family do not have any genetic diseases, generally only the mid-term Down syndrome screening is needed, and there is no need for minimally invasive DNA testing.

Is minimally invasive DNA testing necessary?

No, it depends on the results of Down syndrome screening.

There are Down syndrome screening and NT test before minimally invasive DNA testing. If these two tests are normal, there is no need to do minimally invasive DNA testing. If the previous test results are abnormal, minimally invasive DNA testing or prenatal testing will be necessary.

Generally speaking, if the pregnant woman and her husband's family do not have any hereditary diseases or the pregnant woman herself has no problems, there is no need to do a second minimally invasive surgery. Doctors generally do not require minimally invasive surgery, so there is no need to do it. The prevalence of Down syndrome is also related to the age of the pregnant woman. Generally, the older the woman is, the more strongly she is recommended to undergo minimally invasive testing.

How much does minimally invasive DNA testing cost?

The cost of this minimally invasive examination is generally around 1,500 yuan, which is a self-paid item. Some local governments offer subsidies or companies provide support, so it can be free or at a lower price.

It is best not to test before the twelfth week of pregnancy, because the concentration of DNA in the pregnant mother is too low at this time, and mandatory testing at this time does not meet the testing requirements. After 24 weeks of testing, if the result is not good, then the pregnant woman will generally be advised to undergo an induced abortion, which will cause great harm to the pregnant woman's body. Therefore it must be done after twelve weeks and before twenty-four weeks.

In fact, there is no correlation between the two. In other words, if a woman has passed the NT test, it does not mean that she can pass the minimally invasive test. The NT test is one of the diagnostic methods to check whether the fetus has Down syndrome, while the minimally invasive test mainly checks whether the fetus has other sex chromosome diseases. There is no necessary correlation between the two. Therefore, women's NT examination will not affect the success rate of minimally invasive examinations.

The NT test is based on B-ultrasound examination and is used to screen for fetal abnormalities in early pregnancy. During the NT test, the thickness of the nuchal translucency of the fetus is scanned to determine the condition of the fetus. For minimally invasive tests, only blood tests are needed on pregnant women to detect the physical condition of the fetus from the DNA fragments dispersed in the pregnant mother and obtain the fetus's genetic information.

Moreover, the results obtained from minimally invasive examinations are more accurate than those from NT examinations, and the risk factors are not as high. Therefore, women can undergo minimally invasive examinations with peace of mind. In addition, many parents think that they are healthy and that their fetuses are unlikely to have chromosomal abnormalities, but this idea is wrong, because some genes may mutate when forming sex chromosomes. However, during pregnancy, women should do pregnancy checkups regularly, eat more nutritious foods, and protect the health of the fetus.
