Down syndrome screening is a detection method that extracts serum from pregnant women, tests the concentrations of alpha-fetoprotein, chorionic gonadotropin and free estriol in the maternal serum, and calculates the risk of giving birth to a fetus with congenital defects based on the pregnant woman's due date, weight, age and gestational age at the time of blood collection.

Eugenics and good upbringing are very important for all families, so pregnant mothers must do Down syndrome screening before delivery, which plays a key role in whether the next generation can be conceived healthily.

Down syndrome screening is divided into two phases: the early phase is 9-13 weeks of pregnancy, and the mid-phase is 14-22 weeks of pregnancy. Generally, the results can be obtained within one week after the blood test. If the results show high risk, there is no need to panic. Further amniocentesis and fetal chromosome testing are needed to make a clear diagnosis.
