After pregnancy, women need to undergo various tests, including Down syndrome screening. Down syndrome screening is not a test that needs to be done on an empty stomach, mainly to check the fetus with Down syndrome syndrome, which is also a necessary test for pregnant women. So, should the high risk of Down syndrome screening be taken seriously?
Is the Tang screening high-risk inspection dangerous
The high risk of Down syndrome screening is actually not very dangerous, because the accuracy of Down syndrome screening is not very high, basically around 60%. If high risk of Down syndrome screening is detected, there is no need to worry too much. You can do amniocentesis to further determine whether the fetus has any problems.
What should be paid attention to during Tang screening inspection
1. The best time to do a Down syndrome screening is between the 15th and 20th week of pregnancy, when the accuracy of the screening is relatively high. If it's too late, it's not good to do the Tang screening.
2. Tang screening is not expensive and does not harm the fetus, but its accuracy is not very high, so doctors usually do Tang screening according to the requirements of pregnant women.
3. Tang screening is performed by taking serum samples. When Tang screening is performed, some blood is drawn from the pregnant woman. Currently, fasting is not required. This test is conducted by combining the pregnant woman's serum with the expected delivery date, age, and other factors to check whether the fetus has congenital infertility.
The above is an introduction to whether the high risk of Tang sieve is important. If you are still not familiar with it or are concerned about the danger of Tang sieve's high risk, you can directly go to the hospital for other examinations.
