To avoid having a baby with Down syndrome after birth, pregnant women need to pay attention to Down syndrome screening during pregnancy. If high-risk cases are detected, there is no need to worry too much. Usually, combined with other tests, Down syndrome can be ruled out. So, pregnant women want to know how long it takes for Down syndrome to produce results?
Pregnant women need to undergo Tang screening to check the health status of their fetus. This examination is mainly divided into two stages: one is early pregnancy screening from 9 to 13 weeks of pregnancy, and the other is mid pregnancy screening from 14 to 21 weeks of pregnancy. No matter which screening is conducted, the results can usually be obtained within a week after blood draw. If the test results are not high-risk, there is no need to worry.
Any pregnant woman has a chance of getting pregnant with Down syndrome, so Down syndrome screening is aimed at all pregnant women, and from a medical perspective, Down syndrome screening is very necessary. Pregnant women should attach great importance to this examination. Doing Down syndrome screening can reduce the birth rate of Down syndrome infants. Down syndrome infants have congenital abnormalities in many aspects, often unable to take care of themselves, and many children may die prematurely before reaching adulthood.
In order to avoid the birth of Down syndrome children, it is necessary to detect and take measures early. Moreover, prenatal Down syndrome screening is crucial. The detection rate of trisomy 21 fetuses and early pregnancy NT screening through strict quality control exceeds 80%. Conversely, the detection rate of other chromosomal abnormalities exceeds 70%. If combined with maternal serum testing, the detection rate can be further increased.
