Group B Strep: Understanding Carriage, Risks, and When to Test Yourself at Home

What Does it Mean to be a Group B Strep Carrier?

Many UK adults carry Group B Streptococcus (GBS) in their vaginal or rectal areas without ever knowing it. This harmless carriage usually causes no problems or symptoms. However, it can pose risks during pregnancy, after certain medical treatments, or to individuals with weakened immune systems.

Who’s at Risk with Group B Strep?

• Pregnant women (due to risk of passing it to babies during childbirth)
• Newborn infants (especially preterm or low-birthweight babies)
• People with weakened immune systems

Why Should I Consider a GBS Swab Test?

Symptoms are Rare, but in some, GBS can cause:

• Urinary tract infections
• Vaginal discomfort or discharge
• Infection after certain gynaecological procedures

Routine screening is not offered by the NHS, but testing is recommended if you have symptoms, are pregnant, or have had a previous baby affected by GBS. For more on who should test, see the NHS GBS information.
