Patient's question:
[Condition Description: Trisomy 21 test result 1/45018 Trisomy 21 test result 1/22000 Past treatment history and effectiveness: Had one miscarriage Desired help: Want to know if the child will have problems, the doctor said it is within the safe range, but the risk is highDoctor's answer:
Currently, the triple screen test measures the levels of alpha-fetoprotein (AFP) and human chorionic gonadotropin (β-hCG) in a pregnant woman's blood, and combines the mother's age to precisely calculate the risk of each pregnant woman carrying a child with Down syndrome. The normal value of AFP should be greater than 2.5MoM, and the lower the test result, the higher the chance of the fetus developing Down syndrome. On the other hand, the higher the level of hCG, the higher the risk of the fetus having Down syndrome. Additionally, doctors will input the AFP value, hCG value, the mother's age, weight, and gestational week into the computer to calculate the risk of the fetus developing Down syndrome. If the test results show a risk below 1/270, it indicates a relatively low risk, with the chance of the fetus having Down syndrome being less than 1%. However, if the risk is higher than 1/270, it means the risk of the fetus being affected is relatively high, and further tests such as amniocentesis or chorionic villus sampling should be conducted.
