Tang Screen received a text message saying it was a high risk. Is the result accurate if it is non-invasive

The result of Tang's screening is not very accurate, just a big probability. What will happen if you receive Don's sieve? High risk? Don't be too nervous. Donsiye's accuracy rate is only 70%, but it can't be left unchecked. I feel that if I were that 30%, this kind of luck should be gone.

Generally speaking, Tang screen is literally the same, mainly? Screen? In order to prevent the fish from escaping from the net and make parents pay attention to it, as long as the doctor thinks you need further examination, you will be listed as a high risk, which is responsible for your baby's health. Therefore, even if many pregnant mothers are screened for high risk, there will be no major problems in the end, but it is precisely because of this that pregnant women can receive more accurate examinations.

After receiving high-risk results, there are two options. One is noninvasive DNA, and the other is amniocentesis. 1. Noninvasive DNA

Non-invasive DNA is to extract the peripheral blood of pregnant women, which is simple and easy to operate Older maternal doctors who are prone to fetal chromosomal diseases will suggest skipping the Tang sieve and doing it directly. Non-invasive advantages are less pain, quick response, and results can be produced in about 7 days.

If there is a problem, the hospital will also call directly. If there are no problems, we can get the results of the paper within half a month.

The disadvantage is that although the accuracy rate is higher than that of Tang sieve, it is only 99%, and only three pairs of main chromosomes, 13, 18 and 2 1, are checked. Although there are hints of other chromosomal abnormalities, they cannot be detected specifically. If doing non-invasive DNA also shows high risk, then you will suffer from amniocentesis again.

2. Amniocentesis

Amniocentesis sounds painful. According to my best friend, the needle used to shoot sheep is very thick. If you have been exposed to high-risk chemicals before, or if your parents have a genetic history of chromosomal diseases, you don't even need to do a Tang sieve, just go for amniocentesis. This is to directly insert the needle into the placenta to extract amniotic fluid for analysis. The process is painful, but the result can be 100% accurate.

In the Tang Dynasty, some pregnant women would choose sheep puncture directly after high-risk screening, but it should be noted that amniocentesis can only be done after 18 weeks of pregnancy, and the results are slow. The waiting process is very long, about a month, but it can also be accelerated by adding money. You can consult your local hospital for details.

It should be noted that if you are not the high-risk group I mentioned before, don't go directly for sheep puncture, because it has a one-thousandth chance of miscarriage. If your fetus is unstable or you have contraindications for sheep puncture, you can't do sheep puncture. Just choose non-invasive.

Generally speaking, after receiving the information that Tang Sijie said was high-risk, first check whether you have ever been exposed to teratogenic high-risk chemicals, whether your close family members have a history of genetic diseases in DNA, and whether you have had a fetus with chromosomal abnormalities before. If there is none, non-invasive is enough.

After all, amniocentesis is accurate, but it is expensive and painful, and there is a risk of miscarriage. Many pregnant mothers are pregnant with children, so don't increase the risk of miscarriage. When the non-invasive result is not optimistic, it is too late to arrange the sheep to wear.
