Why is AB negative blood so important?

It’s the rarest blood type and important for platelet donation

AB negative is the rarest blood type, so finding new blood donors can be a challenge.

We can take plasma from AB negative blood donations as it can help treat patients of all blood types.

We generally meet the demand for AB negative blood from our male donors.

This is because female donors (especially those who have been pregnant) can have antibodies that, while no danger to themselves, can be life threatening to patients transfused with their plasma.

If demand for AB negative blood rises, we contact our AB negative female donors directly to ask them to donate blood.

We also need AB negative donors to give platelets. Platelets can help people with cancer and people who’ve lost a lot of blood after an accident, organ transplant or surgery.
