Early Down syndrome screening report

I think many pregnant mothers are familiar with Down syndrome screening. It is mainly used to screen whether the fetus has Down syndrome. Down syndrome, also known as trisomy 21, is a chromosomal abnormality. Babies with this disease are born with congenital retardation, so it is best for pregnant women to have a Down syndrome screening. So how do we judge the Down syndrome screening report?

Down syndrome screening is a new item that pregnant women must do during pregnancy check-up. Down syndrome screening tests the concentration of alpha-fetoprotein (AFP) and human chorionic gonadotropin (β-HCG) in the blood of pregnant women, and takes into account the age of the pregnant women. Computers are used to accurately calculate the risk factors of each pregnant woman having a baby with Down syndrome. Down syndrome screening includes early pregnancy screening and mid-pregnancy screening. Regardless of whether it is mid- to late-stage screening or early-stage screening, pregnant women can generally obtain screening results one week after blood tests.

Generally, the AFP value of the blood cells of pregnant women with congenital idiocy is 70% of that of normal pregnant women, that is, the average MOM value is 0.7-0.8, and the HCG value is higher, with an average MOM of 2.3-2.4. If the test result is high risk, there is no need to worry too much. Next, pregnant women screened in the early pregnancy need to undergo a villus sampling test, and pregnant women screened in the second trimester need to undergo an amniocentesis to obtain the fetal sex chromosomes for fluorescent in situ hybridization, and finally the diagnosis can be confirmed. After all, the MOM value is an average ratio, which fluctuates with the gestational age of the pregnant woman. If these values ​​are within the range, there is no need to panic. The age of the pregnant woman, the number of weeks of pregnancy, the fetal fetal protein secreted by the fetus, the human chorionic growth hormone secreted by the embryo, drug factors, genetic factors, etc. all affect the Down screening value. Many aspects should be considered in making forecasts.

The above is a detailed introduction on how to judge the relevant Down screening test report. In short, you don't need to be on an empty stomach when doing Down syndrome screening, but it depends on your menstrual cycle, weight, height, exact gestational age, and gestational age. It is best to consult your doctor for other preparations before the test. I hope this article can help all pregnant mothers.
