New study seeks help from thousands of blood donors

The blood donor service is looking for volunteers to get involved in a new study to see how often people can give blood.

In total they're looking for 50,000 donors to take part. The research isn't being conducted at visiting clinics but at blood donor centres across the country, including two in the Anglia region, Cambridge and Luton.
