Patient's question:
Can I directly register for the Down syndrome screening in the afternoon of the day I do it?Doctor's answer:
Prenatal screening for Down syndrome is performed between weeks 15-20. The purpose of the screening is to determine the risk of the fetus having Down syndrome by testing the mother's blood. If the results of the screening indicate a high risk of the fetus having Down syndrome, further diagnostic tests such as amniocentesis or chorionic villus sampling should be conducted.
