Common tests for GBS

GBSS believes all pregnant women should be informed about group B Strep and offered the opportunity to have a sensitive test for GBS carriage late in pregnancy.

Whatever the result of a GBS specific test, it is good news. If it detects no group B Strep, that is great. If it does detect GBS, that is also good news – although the baby has a raised risk of developing GBS infection, the risk is known so steps that have been proven to be hugely effective at minimising that risk can be considered.

If you are or have recently been taking antibiotics, this may affect the result of a GBS test. Please discuss this with your health professional.

In the UK, three different tests for GBS carriage may be used and it is important to know which is being offered.
