Down syndrome screening is a very important prenatal screening program that can screen for the risk of Down syndrome in the fetus. In order to be responsible for the fetus and family, pregnant mothers must undergo Down syndrome screening on time. Recently, a pregnant mother who is not familiar with Down syndrome screening wanted to know if Down syndrome screening is closely related to weight?
Down syndrome screening involves extracting blood samples from pregnant mothers and testing for biochemical indicators such as chorionic gonadotropin (HCG), alpha fetoprotein (AFP), and free estriol (uE3) levels. Combined with the mother's age, weight, and actual gestational age at the time of pregnancy testing, the risk of Down syndrome in the fetus can be assessed.
When calculating the results of Down syndrome screening, the weight of the pregnant mother is an essential data. Therefore, it can be seen that there is a certain relationship between Down syndrome screening and the weight of the pregnant mother. However, in the process of calculating Down syndrome screening results, the weight of the pregnant mother's weight data is not significant. In fact, the data with higher weight are the age of the pregnant mother and the gestational age at the time of screening.
Down syndrome screening is usually conducted between 15 and 20 weeks of pregnancy. After examination, if the results show a high risk of Down syndrome in the fetus, further testing should be performed, such as amniocentesis or non-invasive DNA testing after 20 weeks of pregnancy, to ultimately confirm whether the fetus has Down syndrome.
