Patient's question:
A 6-month-old baby cannot lift their head, can roll over, has a normal appetite, and shows no significant abnormalities, but sometimes they experience tremors. If the Down syndrome screening indicates a high risk, what tests should be conducted?Doctor's answer:
Analysis of the condition: Hello, the triple screen test can detect 60-70% of Down syndrome infants. It should be noted that the triple screen test can only help determine the likelihood of the fetus having Down syndrome, but it cannot confirm whether the fetus actually has Down syndrome. In other words, if the blood test index is high, the chance of having a "Down syndrome baby" is higher, but it does not mean the fetus definitely has a problem. On the other hand, even if the test index is normal, it cannot guarantee that the fetus will definitely not be affected.Recommendation: Pregnant women with a triple screen test index above the normal range should undergo amniocentesis or chorionic villus sampling. If the results of amniocentesis or chorionic villus sampling are normal, Down syndrome can be completely ruled out. The best time to perform amniocentesis for prenatal diagnosis is between the 16th and 20th weeks of pregnancy.
