Down syndrome screening is an examination item that we are familiar with. Nowadays, people attach great importance to fertility. Every family hopes that they can give birth to a smart and healthy child. In this case, it is best for everyone to do a good job of Down syndrome screening during pregnancy. Through Down syndrome screening, we can understand whether the baby carried by pregnant friends has problems and effectively prevent misfortune from happening. According to the Down syndrome screening report, we can also distinguish the gender of men and women. 1. How to determine the gender of a baby based on Down syndrome screening results? First look at the MOM value of b-HCG: Below 0.4, most of them are boys; Above 1.0, most of them are girls; It is close to between 0.4 and 1.0, which is the critical value range, and it is possible for both men and women. Then, the combined binomial values (b-HCG and AFp) are more accurate: The lower the b-HCG MOM value (<0.4) and the higher the AFp MOM value (>1), the more likely it is that the baby is a boy. The higher the MOM value of b-HCG (>0.8) and the lower the MOM value of AFp (<1), the more likely it is a girl. In addition, in the blood cells of Down syndrome children and Down syndrome positive children, regardless of whether the fetus is a boy or a girl, the b-HCG value is higher, but the AFp value is slightly lower. 2. What is Down syndrome screening? Down screening is the general name for prenatal selection tests for Down syndrome. The purpose is to test the blood of pregnant women, test the concentrations of alpha-fetoprotein, human gonadotropin and free estriol in the blood cells of pregnant women, and combine the age, weight, and weeks of pregnancy of the pregnant women to determine the risk of congenital idiocy and neural tube defects in the fetus. 3. When should Down syndrome screening be done ? When is the best time to do Down syndrome screening? 15-20 weeks of pregnancy is the best time to do Down syndrome screening. Doctors recommend that Down syndrome screening should be done at 15 to 20 weeks, but each testing hospital has different conditions, so the actual time for Down syndrome screening should be announced by the hospital. This step can predict the possibility of congenital idiocy through examination. The main purpose of Down syndrome screening is to avoid the risk of congenital idiocy in the fetus to a certain extent.
