Patient's question:
I want to do the Down syndrome screening. The doctor said it doesn't matter whether I do it or not.Doctor's answer:
Analysis of the condition: In the Tang Dynasty, screening mainly focused on detecting congenital fetal abnormalities. Suggestions: It can primarily identify conditions such as Down syndrome (21-3 trisomy) and congenital neural and vascular malformations. However, not all conditions can be detected; this is just a screening test.
