Both Tang screening and non-invasive prenatal examinations are required for pregnant women. Generally, if Tang screening fails, non-invasive examinations need to be performed again. Both Tang screening and non-invasive prenatal examination are aimed at checking whether the fetus has Down syndrome, and if so, appropriate measures need to be taken to address it. So, what should we do if Tang Xi and Wu Chuang have not passed?
If both Tang screening and non-invasive examinations have not been performed, it indicates that the risk of fetal chromosomal abnormalities is still relatively high. If so, it is recommended to undergo another amniocentesis examination. Amniotic fluid puncture can be performed between 16-24 weeks of pregnancy in women. The fetus is relatively small and has a lot of amniotic fluid, which is less likely to harm the fetus. The condition of the amniotic fluid can be used to determine whether the fetus is healthy.
If there are no issues with the fetus during amniocentesis, then you can rest assured. However, if there is a high chance of the fetus being Down syndrome during amniocentesis, it is necessary to choose whether to continue the pregnancy based on the doctor's advice. Tang screening and non-invasive testing are both very important examination items, and pregnant women must pay attention to them and go to the hospital for examination on time.
Overall, it is rare for both Down syndrome screening and non-invasive methods to fail. If they occur, it can only be said that there is a high probability of fetal malformation or Down syndrome, and further examination is needed to confirm the diagnosis. If the fetus is indeed found to have chromosomal abnormalities, deformities, or Down syndrome problems, the pregnancy needs to be terminated immediately.
