When is gbs testing done

In newborns, the signs and symptoms of meningitis can be hard to spot. Yes, pregnant women are screened for GBS as part of routine prenatal care. The test for GBS is called a culture. It is now done between 36 and 38 weeks of pregnancy. In this test, a swab is used to take a sample from the vagina and rectum. If the results show that GBS is present, most women will receive antibiotics through an intravenous IV line once labor has started. This is done to help protect the fetus from being infected.

The best time for treatment is during labor. Penicillin is the antibiotic that is most often given to prevent early-onset disease in newborns. While treatment with antibiotics during labor can help prevent early-onset GBS disease in a baby, this treatment does not prevent late-onset disease. If you are allergic to penicillin, tell your health care professional before you are tested for GBS. You may have a skin test to determine the severity of your allergies.
