Patient's question:
I had a glucose screening test at 26 weeks of pregnancy, but after drinking the glucose solution, I vomited more than half an hour later. I asked the doctor, and she said I couldn't eat anymore. The test results showed a value of 5.4. Do I need to redo the glucose screening test? I am currently 29 weeks pregnant. If I want to redo the test, what would be a suitable time?Doctor's answer:
The Down syndrome screening is mainly aimed at identifying the risk of trisomy 18, trisomy 21, and neural tube defects at an early stage for timely intervention. However, it is not a mandatory test for every pregnant woman. But for high-risk groups, it is recommended to undergo the test. Common high-risk factors include pregnant women over the age of 35, those who have previously given birth or have a family history of Down syndrome children, exposure to teratogenic factors such as radiation or viruses during the early stages of pregnancy, and a fetus indicated by ultrasound.
