Scientific discovery

INTERVAL is a ground-breaking study to find out the optimum interval between donations for different donors to safely give blood.

The study is the first of its kind and is set up in collaboration with the Universities of Cambridge and Oxford. We are gathering evidence from 50,000 donors and investigating whether donation intervals should be tailored to donors by age, gender, genetic profile and other characteristics. The results will help us improve donor safety and could shape the future of blood donation nationally and internationally.
