During pregnancy, doctors recommend undergoing a Down syndrome screening. Tang screening is mainly used to check whether the fetus has Down syndrome. This disease can lead to a decline in fetal intelligence, alleviation of growth and development, and even a distinctive facial appearance. Early detection of fetal problems during pregnancy can lead to early treatment. Can I undergo Tang screening at 15 weeks of pregnancy?
At 15 weeks of pregnancy, a Down syndrome screening can be performed, usually at 15-20 weeks, with the best time being between 16-18 weeks for examination. Tang screening is to extract serum from pregnant women, detect the concentrations of alpha fetoprotein and chorionic gonadotropin in their serum, and calculate the risk factor of Down syndrome by testing the serum and combining it with the pregnant woman's weight, age, and other factors.
The function of Tang screening is to screen chromosomes, conduct specialized examinations for Down syndrome, neural tube defects, and 18 body syndrome, and assess the risk of abnormalities. This is because the use of prenatal serum for screening abnormalities is more common and safer. Especially being able to exclude children with Down syndrome.
Down syndrome is mainly caused by abnormal development due to genetic mutations during the preparation for pregnancy or the formation of fertilized eggs. It is also possible that it is a congenital genetic problem, influenced by genetic factors, leading to abnormal fetal development. This possibility can be ruled out through Down syndrome screening.
