summary

summary Down's syndrome screening is a test for Down's syndrome. Prenatal screening of Down's syndrome is not equal to prenatal diagnosis. Positive screening results do not mean that the fetus must be congenital fool. What causes Down's syndrome? Let me talk about it. Reason 1: there is a history of virus infection before and after pregnancy, which may lead to fetal congenital stupidity or congenital malformation, for example, influenza infection during pregnancy, pregnancy after drinking, and excessive use of hormone drugs by pregnant women. Reason 2: one of the couples is older, sperm or egg is easy to age or chromosome aberration, which makes the fetus more likely to suffer from Down's syndrome. Reason 3: pregnant women who have had habitual abortion, premature delivery and stillbirth may have chromosomal abnormalities.
