In recent years, more and more people have been suffering from Down syndrome. Looking at this terrible data, many expectant mothers cannot help but worry. They are always worried that their babies will also suffer from this disease, so they want to know through examination. So, can Down syndrome be detected in the late stage of pregnancy?
1. Down syndrome screening can detect Down syndrome infants by examining various substances in the serum, and then calculating and testing based on the expected delivery date and age of the expectant mother. Actually, every pregnant woman should undergo Down syndrome screening, and the best time to do this test is between 15 and 20 weeks of pregnancy.
2. It can also be checked in late pregnancy, but the results may not be accurate at the optimal time. In fact, the causes of Down syndrome are quite complex, related to genetic factors. Genetics is the most important factor. If the first child born to both spouses is Down syndrome, the second child is highly likely to be Down syndrome. Moreover, if the pregnant woman is too old, it is also easy to cause Down syndrome.
It is not possible to completely detect Down syndrome through Down syndrome screening tests. Many babies are only diagnosed with Down syndrome after birth. Therefore, in order to avoid the occurrence of Down syndrome, it is recommended that expectant mothers pay more attention during pregnancy, avoid areas with excessive pollution, and develop good lifestyle habits.
