summary

Down's screening is a test item for pregnancy, which is very important for pregnant women. So down's screening also has its own time requirements, let's see when Down's screening is ready.

When is down's screening ready

First aspect: from 14 weeks of pregnancy, as a mother to be, it is best to carry out down syndrome screening. S syndrome is a congenital fetal malformation that we often see in clinic, which is caused by the formation of chromosomes in the process of development.

Second, in the normal population of childbearing age, the incidence of trisomy 21 is 800 to 1 in 1000, and there is no obvious genetic tendency. So it is necessary for every expectant mother to be responsible for herself and do the examination in time.

The third aspect: at present, the best time for Down's screening is 14 weeks + 6 days to 18 weeks + 6 days, and the best time is between 16 and 18 weeks. If you miss this time, you can't continue to do this examination.

matters needing attention

The significance of Down's screening is still relatively large, but this project is optional. However, we suggest that expectant mothers should do it in time for their babies. At the same time, it reminds expectant mothers that amniocentesis is risky.
