Women must undergo regular check ups during pregnancy, especially for prenatal screening and prenatal screening, which can prevent the birth of defective children. Some pregnant women may experience high or moderate risk after undergoing Down syndrome screening. So, could Tang Shi be a child of Tang Shi?
The result of moderate risk after Tang screening examination may not necessarily be Tang's child. Because the accuracy of Tang screening is not 100%, its highest accuracy is 70%. Moreover, the Down syndrome screening test is used to determine the likelihood of the fetus developing Down syndrome, and cannot fully confirm whether the fetus has Down syndrome. This means that when the risk index is high, it indicates a higher likelihood of developing Down syndrome, but it does not necessarily mean that the fetus will have problems. For example, elderly pregnant women have a higher chance of having Down syndrome babies after pregnancy, but it does not necessarily mean that the fetus will be sick.
Conducting a Down syndrome screening can only determine the probability of the fetus developing Down syndrome, but it is not clear whether the fetus will develop Down syndrome. If the results of the Down syndrome screening indicate that the fetus is at risk of developing Down syndrome, then the pregnant woman needs to undergo the next step of examination, which is amniocentesis. By amniocentesis, it is possible to determine whether the fetus has Down syndrome. Many elderly and high-risk pregnant women do not undergo Down syndrome screening, but directly undergo amniocentesis examination.
