Some women are fortunate enough to be pregnant with twins. During pregnancy, special attention should be paid to conducting various prenatal examinations to ensure the healthy development of the fetus. Down syndrome screening is very important among these examination items, and pregnant women must not miss this examination. So, what about high-risk Down syndrome screening for twins?
Pregnant women should pay attention to doing Down syndrome screening tests between 14-18 weeks, and the latest should not exceed 20 weeks. It is meaningless to do tests after that. Down syndrome screening uses venous blood to examine the absence of neural tube defects in fetuses. If high risk is detected, it does not necessarily mean that the fetus has a problem, and of course, low risk does not guarantee that the fetus has no problems.
The Down syndrome screening result is high-risk, indicating a relatively high risk of the fetus having Down syndrome. The reasons for the occurrence of such examination results include the older age of the pregnant woman, the decline in ovarian function, and the poor quality of the eggs released, which can lead to a higher risk of examination; In addition, a family history of giving birth to malformed fetuses or having Down syndrome children in the family can also have some impact on the examination results.
After a pregnant woman undergoes Down syndrome screening and shows symptoms of high wind clearance, do not worry too much. Doctors will guide the pregnant woman to undergo further examinations based on her condition, such as amniocentesis, etc. After a series of examinations, it can be determined whether the fetus has any problems. Pregnant women only need to maintain a relatively stable mood and wait for the test results.
