Why is B negative blood important?
It’s one of the rarest blood types
B negative donors are immensely important to our lifesaving work.
As B negative is one of the rarest blood types, it is hard to find new donors and to ensure we always collect enough blood.
We always need more B negative donors and rely heavily on the support and commitment of existing donors to ensure patients receive the blood they need.
