Does the Down syndrome screening have anything to do with the pregnant woman's date of birth?

Patient's question:

Today, I saw the screening results showing that the risk of Down syndrome exceeded the predetermined screening standard. The birth date I reported was the lunar calendar (19820812). I would like to ask if this is related to it. Thank you!

Doctor's answer:

Disease Analysis: Generally, the Down syndrome screening is mainly targeted at children with Down syndrome. Pregnant women of advanced maternal age should pay attention.
Guidance: Based on your condition, your current situation is that the risk of Down syndrome exceeds the predetermined screening standard. Therefore, further amniocentesis is necessary to evaluate your condition. This test is more accurate than the Down syndrome screening results, so you must undergo it. You do not yet qualify as a high-risk pregnant woman.
