What is early pregnancy antenatal screening?

Now everyone's economic ability has been improved, so many women have to undergo various examinations regularly when they first become pregnant. Through examinations, some fetal diseases can be screened in time, such as congenital idiocy and open neural tube defects, etc. Many congenital diseases are often related to genetics and are also affected by environmental factors. So what is early pregnancy prenatal screening?

First, what is prenatal screening in early pregnancy? Prenatal screening refers to some medical and daily care related behaviors implemented on pregnant women. Its purpose is to check the health of both mother and baby, do preventive work and detect complications as early as possible, so as to minimize the impact of the disease. Through screening, doctors can conduct regular examinations for pregnant women and give scientific advice, which can reduce the mortality rate of women during pregnancy and the mortality rate of infants near birth. It is very necessary to conduct this series of examinations before delivery, which is of great significance to the health of mother and baby. Prenatal screening can effectively reduce the rate of newborn birth diseases because it can predict defects in the fetus while it is in the mother's womb. Combined with prenatal diagnosis, it can minimize the birth of babies with congenital defects. Therefore, expectant fathers and mothers must actively cooperate.

Second, when pregnant, mothers should undergo prenatal screening. The detection method is very simple. It only requires a certain amount of blood to be drawn from the pregnant woman for testing, mainly to detect the levels of chorionic gonadotropin and alpha-fetoprotein. The mother's age and the time of pregnancy when the blood test was taken should be considered comprehensively to calculate the risk index of possible diseases in the fetus. If the risk index is very high, it means that the fetus has a high probability of suffering from a certain genetic disease.

What is early pregnancy prenatal screening? It generally checks for three congenital diseases with a higher incidence rate, namely Down syndrome, trisomy 18 and open neural tube defects. The incidence rates of the above three congenital diseases are relatively high. Although congenital diseases such as neural tube defects and congenital idiocy are also hereditary diseases, they are mainly affected by the environment, and it is difficult to judge the possibility of the disease based solely on family history. For safety reasons, it is best for expectant mothers who have the conditions to undergo prenatal screening. It should be noted that prenatal screening is only a predictive measure and cannot guarantee that the test results are correct. If the test results are high risk, timely treatment is required.
