GBS Screening

Group B Streptococcus (GBS) is a common type of bacteria found in the internal genitalia/vagina, rectum, or urinary bladder of individuals whether pregnant or not. GBS usually does not cause infections in pregnant individuals, but is of concern for the baby. At 35 to 37 weeks of pregnancy, your health care provider will offer you a vaginal swab to check if you have GBS. If you test positive for GBS, your health care provider will offer you antibiotics during labour in order to prevent the spread of the infection to your baby. The majority of babies born to pregnant individuals with GBS are not affected by the bacteria, however, a very small number of these babies will develop a serious infection. For more information on the risk factors, screening, management and what your choices are regarding GBS screening, please check out the resources below.
