We will be recruiting women from 80 sites in England, Wales and Scotland. 40 sites will be randomised to the current UK policy. 20 sites will undertake testing using a bedside machine. 20 sites will undertake testing at 3-5 weeks before the expected labour due date.

We are currently in the process of opening our first sites, more details to follow. If you would like your Hospital to be involved in the GBS3 trial, please email: GBS3@nottingham.ac.uk .
