Patient's question:
In a few days, I will accompany my pregnant 17-week sister-in-law to the hospital for a thorough check-up. I want to ask the doctor in advance if fasting is required for the Down syndrome screening. Will eating before the Down syndrome screening affect the test results? Can a 18-week pregnant woman undergo Down syndrome screening?Doctor's answer:
The Down syndrome screening is recommended to be done between weeks 15-20 of pregnancy. Weeks 1 or 18 are relatively suitable. This detailed examination does not require fasting, as diet has no impact on the test results. Before the examination, it is mainly necessary to undergo an ultrasound to verify the gestational age. Once the gestational age is confirmed, you can proceed with the examination.Throughout the rest of the pregnancy, follow the doctor's advice to have regular prenatal check-ups and maintain a diversified diet to ensure comprehensive nutrition.
