Someone in need of a transplant is most likely to find a match in a person with a similar genetic history. That often means someone from the same ethnic background.

People from minority ethnic backgrounds often have rarer tissue types which makes it harder to find matching donors. That means we need to recruit even more donors from minority ethnic backgrounds so they are overrepresented on the register.

This includes people from African, African-Caribbean, Asian, Chinese, Eastern European, Mediterranean and mixed race backgrounds.
