Whose type can you match?
Donors with type O- blood are universal red cell donors whose donations can be given to people of all blood types. Donors with types AB- and AB+ blood are universal plasma donors, while patients with type AB+ are universal red cell recipients because they can receive red cells from all types. All other donors and recipients must be safely matched, for example:

| O- | 7% | O+ A+ B+ AB+ O- A- B- AB- | O- |
| A+ | 34% | A+ AB+ | O+ A+ O- A- |
