Question
How do I go about getting a Down syndrome screening? I’m currently 21 weeks pregnant and have heard that it’s necessary to have the screening done to ensure the health of my baby. What do I need to prepare for before undergoing this screening, and how exactly is it conducted?
Answer
Down syndrome screening involves assessing the risk of fetal Down syndrome. The risk for Down syndrome is determined through a blood test around the 24th week of pregnancy. The screening process involves drawing blood from the expectant mother, and the risk factors for a Down syndrome baby are calculated based on the mother’s pre-pregnancy, weight, age, and gestational age. After the Down syndrome screening test, you should refrain from eating or drinking anything after 12 pm the day before the test and continue to fast until you arrive at the testing hospital the next day.
