A person can safely receive a transfusion from another person provided the receiver's blood contains all of the A, B, and
Rh factors of the donor. So a person with B* blood can receive blood from persons with types B. B",o*, and O
but not with types A . A . AB*, and AB. (For an explanation of blood type classifications, see below.)
Describe using set notation the set of blood types of persons that can receive blood from anyone (universal receivers).
Let A, B, and Rh represent the sets of blood types that contain the corresponding factors.
A person's blood is classified as A, B, AB (has both antigens), or (has neither antigen). Blood having the Rh factor is
classified as Rh positive (+) and if lacking the factor, Rh negative (-). For example, if a person has the A antigen, lacks
the B antigen, and has the Rh factor, her blood would be classified as A.
