Patient's question:
Want to know what the high risk of Down syndrome screening means and how to solve this situation? Consult the doctor.Doctor's answer:
Down Syndrome ScreeningDown syndrome screening is a scientific method for testing how an infant may have genetic defects and is one of the essential examination items that pregnant women must undergo during pregnancy. A blood sample is taken to test the concentrations of alpha-fetoprotein, human chorionic gonadotropin, and free estriol in maternal serum. It is necessary to estimate the risk factors for the birth of a fetus with congenital defects by combining the expected delivery date, weight, age, and gestational age at the time of blood collection. Down syndrome screening can only help confirm the probability of the fetus having Down syndrome but cannot determine how the fetus developed Down syndrome. In other words, the probability of the blood test indicators being "Down syndrome baby" is higher, but this does not predict that the baby definitely has a problem.
