These are, of course, the letters that represent blood groups. This is all in support of the NHS Blood and Transplant #Missing Type campaign to highlight the global importance of blood donation.
The campaign aims to:
- reverse a trend in the decline of new blood donors over the last decade
- contribute to the 204,000 people we need to attend a donation session for the first time to give blood in 2016 to replace people who can’t donate anymore, to make sure we have the right mix of blood groups
