rh factor

the surface of red blood cells contains markers that the immune system can recognize—one of these markers is the rh factor (rh [d] antigen). a person whose blood contains the rh factor is rh-positive (d); a person whose blood does not contain the rh factor is rh-negative (d).

blood type contains information about the presence (+) or absence (–) of the rh factor. blood type is indicated by a letter (a, b, or o) and a symbol (+ or –). if a person has b negative (b–) blood, for example, that person is rh-negative. a person with b positive blood (b+) is rh-positive.
