Tang sieve a few days out of the results

summary

Pregnant about 4 months to do down screening, in order to screen down syndrome. This inspection cost is not high, each place is different, the most expensive is a few hundred yuan, and it must be done in the production inspection project. In terms of my personal experience and the facts of my friends, I would like to say a few points about the high-risk or critical results of Tang Shai. Tang sieve a few days to tell you the results.

Tang sieve a few days out of the results

First: after the screening results come out, the bottom will definitely state that high-risk or critical does not mean there is a problem, while low-risk does not mean there is no problem. So if you get the results of this examination, don't worry, its accuracy may be zero for you.

Second: in the early Tang Dynasty, NT was added to Tang sieve once every three months. In foreign countries, the result of NT is more meaningful and accurate. However, in China, even in the first tier cities like Beijing, few places attach importance to NT.

Third: the result of Tang's screening is a probability value, such as 1:180, which is a high-risk value. It represents that one of the 180 same results may be Tang's, which makes other 179 expectant mothers worried.

matters needing attention

If there is a problem with the results of Tang screening, it will lead to further genetic testing or amniocentesis. The cost of genetic testing is high, amniocentesis is risky, and the cost is not low, and the general hospital can not operate.
