In order for the child to grow up healthy, both men and women will undergo prenatal check ups before pregnancy. Most people think that as long as they do this prenatal examination, there is no need to undergo genetic disease screening after pregnancy. However, there are also some people who are unsure and are torn between doing and not doing it. Is it necessary to screen for genetic diseases in early pregnancy?
Genetic disease screening is still necessary. Generally, Down syndrome screening is performed between 11 and 16 weeks of pregnancy. By testing the pregnant woman's blood, the concentrations of alpha fetoprotein, chorionic gonadotropin, and free estriol in the maternal serum are detected. Combined with the pregnant woman's age, weight, gestational age, and other factors, the risk factor for fetal Down syndrome and neural tube defects is determined.
If it is found to be high-risk, non-invasive DNA testing can also be performed; Perform a four-dimensional examination between 20 and 24 weeks to exclude any abnormalities on the surface of the fetus and any abnormalities in the fetal heart. In addition, it is also possible to consult a specialist for genetic disease testing by taking chorionic villi in early pregnancy or amniotic fluid in mid pregnancy.
Many families feel that genetic diseases have nothing to do with themselves, as long as they and their partners are in good health. In fact, it is not the case. If someone in the family has had a related genetic disease, it is possible to be inherited. Moreover, some genetic diseases have recessive genes. Although the probability of inheritance is low, it is still necessary to cooperate with doctors to conduct corresponding examinations for the health of the baby and the happiness of the family.
