Blood groups are classified based on the presence or absence of antigen A and B and the third antigen Rh factor on the surface of red blood cells. Based on this there are eight types of blood groups: O+, O–, A+, A–, B+, B–, AB+ and AB–.

The O– blood group is the universal donor and AB+ is the universal recipient. However, in some cases, when only plasma is required, AB plasma is the universal donor.
