Patient's question:
I just got pregnant for one month. My sister told me that the Down syndrome screening is a very important prenatal test. This is a very important part, very useful, able to screen the possibility of Down syndrome. At what month of pregnancy should Down syndrome screening be done?Doctor's answer:
Down syndrome screening is divided into early Down syndrome screening and mid-pregnancy Down syndrome screening. The initial screening time is from 9 weeks to 12.3 weeks, and the mid-pregnancy screening time is from 16 weeks to 20 weeks. Therefore, the specific discussion is about the screening time, which should be determined based on individual circumstances and procedures. If the age is over 35, it is recommended to directly undergo non-invasive DNA testing. It is also advisable to pay more attention to rest and consume more nutritious foods during pregnancy.
