The reason for this is that there is no scientific basis for the statement that nine out of ten people are at high risk, so don’t have too much of a psychological burden. The high-risk group for Down’s syndrome screening is mostly found in older mothers, i.e. those who are older than 35 years old. However, the result of Down’s syndrome screening is only a prediction of the probability that the fetus may have the disease, it does not mean that the fetus is 100% diseased, so doctors recommend a detailed DNA test for the fetus to accurately determine whether the fetus will have congenital diseases. Therefore, it is necessary for pregnant women to go to the hospital for timely check-ups in the early stages of pregnancy to confirm the physical condition and intelligence of the fetus. If the results are not promising, the pregnancy can also be terminated early to avoid the fetus from being born with the disease and to reduce the burden on the family. In addition, pregnancy checkups also allow pregnant women to understand their physical condition so that they can regulate their body during pregnancy and deliver the fetus successfully.
