Down’s syndrome screening is a special and important test that is usually referred to as prenatal screening for Down’s syndrome.
Down’s syndrome is a special and important test that is performed by testing the vein blood of a pregnant woman to detect the concentration of alpha fetoprotein, chorionic gonadotropin, and free estriol in the mother’s serum. The test is also based on the mother’s weight, age, and week of gestation, in order to determine the risk of congenital anomalies, such as congenital stupidity, and neural tube malformations in the fetus.
Down syndrome, or trisomy 21, is a disease caused by chromosomal abnormality. Most fetuses are aborted during pregnancy, but some fetuses survive to give birth and may suffer from significant intellectual backwardness, peculiar facial features, growth disorders, and multiple malformations.
Pregnant women need to cooperate with their doctors to undergo Down’s syndrome screening during pregnancy, and in the case of high risk, non-invasive DNA or amniocentesis is required for further clarification if necessary.
