After pregnancy, it is necessary to undergo Down syndrome screening, which mainly checks the risk index of Down syndrome in the fetus. And the time to do Tang screening is not just for pregnant women to do it at any time they want. Can Tang screening still be done after 20 weeks?
1. Tang Screen Time. The testing time for Tang screening is between 16-20 weeks of pregnancy, preferably between 16-18 weeks of pregnancy. If a Down syndrome screening is performed after 20 weeks of pregnancy, its accuracy may be affected, so it is not recommended to undergo a Down syndrome screening.
2. Tang sieve price. Tang screening is a necessary examination, and many pregnant women want to know the price of Tang screening clearly. In fact, the fees vary from region to region and from hospital to hospital, with a price of around 200 yuan.
3. Tang Xi needs to eat on an empty stomach. Many pregnant women believe that blood tests require fasting, but Tang Shi does not require fasting. However, if pregnant women need to undergo other tests, such as liver function tests, then fasting is necessary.
4. What should we do if Tang Xia is at high risk? I believe this is a concern for many pregnant women. In fact, the high risk of Down syndrome screening does not necessarily mean that the fetus is a Down syndrome child, but rather that the risk index of the fetus being a Down syndrome child is relatively high, and further examination is needed to determine. Pregnant women can undergo amniocentesis under the arrangement of a doctor to determine whether the fetus has Down syndrome.
