Around the 36th week of pregnancy, the woman will be screened for Group B Streptococcus (GBS). This is a very simple test to determine if GBS is present in the gastrointestinal and/or genitourinary tract of the pregnant woman. Therefore, there are two possible results:
- Negative result: there is no presence of GBS at that time and no treatment is required.
- Positive result: GBS is present and the woman will receive intravenous antibiotic at the time of delivery.
The antibiotic is not administered until the time of delivery, in case of a positive result, because the bacteria could re-grow after treatment.
