According to studies by the World Health Organization (WHO), the rate of birth defects in newborns is 1.73%, every year around the world about 8 million babies are born with a birth defect. In Vietnam, there are about 1.5 million babies born every year, of which 2-3% have genetic diseases and birth defects such as Down's disease (intellectual retardation), syndrome Edwards (defects caused by extra chromosomes), neural tube defects, G6PD deficiency (children do not have enough of this enzyme, the red blood cells are difficult to function properly), congenital adrenal hyperplasia; have Thalassemia (congenital hemolysis)...
Birth defects can happen at any time during pregnancy, but most often during the first trimester, when your baby's body parts are forming. Therefore, prenatal screening tests are extremely important, not only to help detect birth defects for the fetus, but also to improve and improve the quality of the breed. Therefore, this is a necessary job to help mothers detect diseases, give birth to a healthy baby and develop normally.
