Patient's question:
After getting pregnant, I'm always afraid that the child might have some kind of bad illness. I just had the Down syndrome screening a few days ago. Is the Down syndrome screening during pregnancy accurate?Doctor's answer:
I'm glad to help you clarify your questions. The prenatal screening for Down syndrome is a basic diagnostic test for fetal abnormalities, primarily used in early pregnancy to rule out trisomy 21 in the fetus. If the results of the screening indicate a high risk, further non-invasive DNA testing is required. Non-invasive DNA testing is a more accurate diagnostic test for fetal abnormalities compared to the standard screening. If the non-invasive DNA test results are normal, there is no need to undergo further testing.
