Group B Strep is a bacterial infection that is found in approximately 25% of all normal, healthy women. Most women who test positive do not have any symptoms. A woman who is pregnant and tests positive for GBS, however, has the possibility of passing GBS to her baby during delivery. Some, but not all babies exposed to GBS during delivery can become quite ill.
A routine part of testing during pregnancy includes Step B testing during a patient’s initial OB lab panel. Patients are also screened during the 36th week of pregnancy. If a woman is found to be positive, steps can be taken during labor to prevent GBS from being passed on to her baby.
