In order to get an accurate answer and avoid accidents, we need to first understand at how many months pregnant women should do Down syndrome screening?

How many months of pregnancy should you do Down syndrome screening?

Down syndrome screening is a prenatal examination item that can determine whether the fetus suffers from congenital head or central nervous system development disorders based on the concentration of alpha-fetoprotein, human gonadotropin and free estriol in the pregnant woman's blood. After obtaining the test data, it can be determined based on the natural body conditions of the pregnant woman (including but not limited to weight and age) to determine whether the fetus has congenital head or central nervous system development disorders.

Pregnant women also need to know the time of Down syndrome screening. The best time to conduct Down syndrome screening in early pregnancy is 12 weeks. The time for mid-pregnancy Down syndrome screening is between 14 and 20 weeks of pregnancy, and the best time to check is between 16 and 18 weeks. Whether it is early or late, the test results of Down syndrome screening will be affected to a certain extent.

What is Down syndrome screening?

Down syndrome screening is a very important test. Please do not relax your vigilance. Its purpose is to determine whether the fetus is at risk of Down syndrome by testing the pregnant woman's blood. If the Down syndrome screening data shows that the fetus has a high risk of Down syndrome, further diagnostic tests should be carried out.

Children with Down syndrome are not exclusive to older pregnant women, although older pregnant women over 35 years old are closely related to Down syndrome, that is, the older they are, the greater the probability of having a child with Down syndrome. However, young women may also have children with Down syndrome, which is random.

Clinical medicine shows that only 20% of Down syndrome occurs in older pregnant women, and the other 80% of Down syndrome children are born in young pregnant women under 35 years old. Therefore, both young and older pregnant mothers need to undergo Down syndrome screening.

Having a smart baby at home is everyone's dream, but accidents are inevitable. In order to get timely medical treatment, it is necessary to understand the health of the fetus through various tests. Please pay great attention to Down syndrome screening. Timely and effective examinations can prevent accidents, allow healthy babies to be born, and have happy and harmonious families.
