Patient's question:
NoDoctor's answer:
Hello, Down syndrome screening is a method that involves drawing pregnant women's blood serum to detect the concentration of alpha-fetoprotein and human chorionic gonadotropin in the mother's serum. It also combines the pregnant woman's estimated due date, age, weight, and gestational age at the time of blood collection to calculate the risk coefficient of giving birth to a child with Down syndrome. The best time to perform Down syndrome screening is between the 15th and 20th weeks of pregnancy. In your case, you have already passed the optimal time for the test, so it would not be accurate to do it now. Currently, it is recommended to undergo a 3D ultrasound to check the development of the fetus. If everything is normal, there is generally no need to be too concerned.
