Down syndrome screening is a prenatal examination that every pregnant woman must undergo to rule out any congenital abnormalities in the fetus. Generally, it is best to undergo Down syndrome screening around the 15th week of pregnancy. But some people say that the gender of a baby can be determined through the results of Down syndrome screening. So, are all Down syndrome screenings greater than 1 female baby? Let's learn about it together with the editor below.
Down syndrome screening is greater than 1
Down syndrome screening is to check the concentration of alpha fetoprotein (AFP), chorionic gonadotropin (HCG), free estriol, etc. in maternal serum. Down syndrome screening does not have an accurate value, only a proportion. When the blood test screening value is greater than 1/270, it is a high-risk population, and the normal value is around 1/700. The international standard is 1/270. If the Down syndrome screening is greater than 1, it cannot determine the gender of the baby.
What are the functions of Tang sieve
Down syndrome screening is the abbreviation of prenatal screening examination for Down syndrome. It involves testing the blood of pregnant women, detecting the concentrations of alpha fetoprotein, chorionic gonadotropin, and free estriol in maternal serum, and combining the age, weight, gestational age, and other factors of the pregnant woman to determine the risk of congenital Down syndrome and neural tube defects in the fetus. Generally speaking, there are differences between the generated reports due to different detection instruments. Simply put, as long as it is one's own measured value, it should be below the reference risk assessment value (the larger the denominator, the lower the risk).
Down syndrome screening is very necessary for every pregnant mother, especially for elderly pregnant women who should actively cooperate with doctors to undergo Down syndrome screening, and if necessary, further examinations such as puncture should be carried out. Tang screening is used to detect fetal abnormalities and cannot determine the gender of the baby, so pregnant mothers need to maintain a positive attitude.
