[C20: named after the rhesus monkey, in which it was first discovered]

Rh factor

(ˈɑrˈeɪtʃ)
n.
any of a group of antigens on the surface of red blood cells, those having inherited such antigens being designated Rh + (Rh positive) and those lacking them, a much smaller group, being designated Rh− (Rh negative) : transfused or fetal Rh + blood may induce a severe reaction in an Rh− individual.
[1940–45; so called because first found in the blood of rhesus monkeys]

Rh factor

(är′āch′)
An antigen present in red blood cells, used in the classification of human blood. The blood cells of most people contain an Rh factor. For a blood transfusion to be successful, the blood of the donor must match that of the recipient—both must have or must be missing the Rh factor.

There are four major blood groups determined by the presence or absence of two antigens - A and B on the surface of red blood cells: Group A has only A antigen on red cells (and B antibody in the plasma); Group B has only the B antigen on red cells (and A antibody in the plasma); Group AB has both A and B antigens on red cells (but neither A nor B antibody in the plasma); and Group O has neither A nor B antigens on red cells (but both A and B antibodies in the plasma.) Aside from A and B antigens, there is a third antigen called the Rh factor, which indicates either present (+) or absent (-).
