There are various types of examinations for women during pregnancy, and some pregnant women feel that doing so many examinations is not very useful. They think that some items can be avoided, such as prenatal GBS examinations. This idea is very wrong, even dangerous. Every examination during pregnancy is useful. So, what is the purpose of prenatal GBS examination?
GBS examination is to check for Streptococcus agalactiae, a bacterium that parasitizes the vagina and intestines of women. If a woman has strong resistance, it will not cause illness, but when her resistance decreases, it will cause trouble. Many women have this bacteria in their bodies, and newborns are easily infected when passing through the birth canal. If pregnant women have this bacteria in their bodies and no measures are taken, the infection rate of newborns born naturally can reach over 90%. So in order to prevent babies from being infected with Streptococcus agalactiae, pregnant women must undergo prenatal GBS testing.
GBS poses great harm to newborns and is a common cause of sepsis and meningitis in newborns. 30% of pregnant women have GBS in their bodies. If a pregnant woman undergoes vaginal delivery, the vast majority of fetuses will be infected, and some fetuses may even be infected in the female uterus. This can cause the child to develop pneumonia and sepsis before birth, and may also lead to fetal death in the uterus. So women should undergo prenatal GBS examination after pregnancy.
