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.
