The eight types are A+, A-, B+, B-, AB+, AB-, O+, and O. These four groups expand to eight types with the presence (+) or absence (-) of a protein called the Rh factor.
This is especially true when the recipient’s blood type is unknown or in the case of an emergency when there is no time to test the recipients blood group.
