Patient's question:
What does "low risk" written on the first screening test for Down syndrome mean?Doctor's answer:
Down syndrome screening, as the name implies, is a prenatal test for screening fetuses with Down syndrome. Experts explain that by drawing and testing the pregnant woman's blood, it serves as a key indicator for screening trisomy 21 syndrome in the fetus. The results of Down syndrome screening have two categories: low risk and high risk. This test is merely a probability issue and cannot determine whether there are congenital abnormalities. If you have undergone Down syndrome screening and received a low-risk result, and you have also had a non-invasive DNA test with a result below the threshold, you can rest assured that there is no problem. However, if the result is high risk, you should pay attention.
