Screening tests during pregnancy: Screening for Group B Streptococcus (GBS)

Group B Streptococcus (GBS) is a common strain of bacteria that exists in the intestinal tracts. Although GBS is usually harmless in adults, it may cause serious infection and stillbirth in growing fetuses. The bacteria may harbour in the vagina and be passed on to the baby during labour and delivery. To this end, GBS is life-threatening and usually affects the baby in the first 24 hours and up to a week after birth.

Screening for Group B Streptococcus will reduce the chances of the baby getting infected, once the mother receives medical treatment such as oral antibiotics.
