What is the prenatal screening for Down syndrome?

Patient's question:

No

Doctor's answer:

Through the blood draw and testing of pregnant women, important indicators for screening fetal trisomy 21 syndrome are identified. Based on the screening results, it can be determined whether the fetus has congenital intellectual disabilities and the risk level of the fetus suffering from Down syndrome. If the screening results are high-risk, further diagnostic testing—amniocentesis—is required.
