Down syndrome screening is also a prenatal examination that pregnant women need to undergo, mainly used to screen whether the fetus will have Down syndrome. Some pregnant women may also have high-risk screening results when undergoing this examination. So, what are the impacts of high risk of Down syndrome screening?
1. During pregnancy, women go to the hospital for Down syndrome screening. If there are high-risk screening results, it indicates that the fetus may have Down syndrome. If diagnosed with this disease, it will have a serious impact on the health of the fetus. However, although there is generally a high risk of Down syndrome screening, its accuracy is not very high, so it does not necessarily mean that the fetus will have Down syndrome. This is just a screening result, not a prenatal diagnosis.
2. If there is a high risk of Down syndrome screening, pregnant women should not be too nervous, as multiple prenatal checkups are required in the following weeks of pregnancy. For pregnant women who were initially at high risk of undergoing Tang screening, non-invasive DNA testing can also be used to determine whether the previous test results were false positives.
3. If there are still high-risk factors after this test result, amniocentesis can also be performed. This method extracts fetal amniotic fluid test substances for laboratory analysis, which has good accuracy and can make accurate prenatal diagnosis of whether the fetus will have abnormalities.
