In the past, the prenatal diagnosis of this kind of disease was only through amniotic fluid or chorionic villus examination, but these methods are long-time, expensive and troublesome to operate, and are limited to some high-risk pregnant women. According to statistics, about 80% of fetal chromosomal diseases occur in ordinary pregnant women, because the absolute fertility value of this group exceeds that of high-risk groups, so prenatal diagnosis from the perspective of eugenics can not be ignored. The actual situation is that the prenatal diagnosis department of this group can't bear it so far, which eventually makes this group a blind spot for eugenics. The emergence of 1988 serum marker screening method has fundamentally changed the passive situation of prenatal prevention of the above diseases.
