Spotlight: Group B Strep (23) Question for Marti - The limitations of screening

9 July, 2026

Good morning, this question is for Marti.

The limitations of screening

My 36-week GBS screening was negative, yet Finley developed early-onset GBS disease. Until she died, I had no idea that colonization can change between screening and delivery.

How often does this happen, and what should parents and clinicians understand about the limitations of current screening?
