Patient's question:
My wife is currently pregnant, but we haven't had the Down syndrome screening before. What should we do if we didn't have the Down syndrome screening during pregnancy?Doctor's answer:
Down syndrome screening is now a mandatory test, primarily aimed at ruling out the risk of Down syndrome. This is a congenital chromosomal abnormality that leads to developmental delay, and children born with it often have intellectual disabilities and most also suffer from congenital diseases. They generally lack self-care abilities. If your wife did not undergo this screening during pregnancy, you could consider undergoing a non-invasive DNA test, which can also rule out this risk. Moreover, this test has a higher accuracy but comes at a higher cost.
