Additional Notes

GBS screening is an important test for pregnant women. If a woman tests positive for GBS, it does not necessarily mean that her baby will become infected. However, it is important to receive antibiotics during labor to reduce the risk of transmission to the baby. Women who test negative for GBS at 35-37 weeks of pregnancy do not need to be retested, even if labor is delayed or prolonged.
