Patient's question:
Hello expert, today I took my little son for a Down syndrome screening and Down syndrome evaluation. Here, I would like to ask, after I went to the hospital today for a Down syndrome screening and Down syndrome evaluation, what are the normal values? I hope to see a doctor who can give me a reference. Thank you.Doctor's answer:
Down syndrome screening is not a detailed examination for the baby. Down syndrome screening is performed between weeks 15 and 20 of pregnancy by extracting peripheral blood from the pregnant woman to test three hormones. It then combines the pregnant woman's age, weight, and gestational age to conduct a prenatal imaging screening. If the baby has already been born, it is recommended that the mother should follow up at the pediatric department. The pediatrician will then assess the baby's facial features and physical appearance to determine the likelihood of Down syndrome.
