When should a woman be tested for group B strep (GBS) if she is pregnant?

A woman should ask her doctor or nurse for a group B strep (GBS) test when she is 35 to 37 weeks pregnant. The test is an easy swab of the vagina and rectum that should not hurt.

Each time a woman is pregnant, she needs to be tested for GBS. It doesn't matter if she did or did not have this type of bacteria before; each pregnancy is different. The only time you don't need the test and will automatically be recommended antibiotics during labor is if you've delivered a previous baby with early-onset GBS disease, or if the bacteria were found in your urine at any time during this pregnancy.
