There are many concerns for mums-to-be during every phase of pregnancy, as well shortly after birth. Our Group B Streptococcus test is designed to protect newborn babies from possible infection from the Group B Streptococcus bacteria, and to give new mothers one less thing to worry about. 

Group B Streptococcus is a type of bacteria that is very common – up to 2 in 5 people have it living in their body, usually in the rectum or vagina. The bacteria is common in pregnant women and rarely causes any problems. However, there is a risk that it passes to the baby in pregnancy or during delivery which could make them ill. A positive test result may lead to antibiotics being administered during delivery to protect the baby if the mother is considered to be in a high-risk group.

This test is the gold-standard ECM (enriched culture medium) test for Group B Strep. It includes 2 swabs; one vaginal and one rectal which should be performed between 35 and 37 weeks of pregnancy. A positive result should be shared with your midwife or consultant.
