blood type (blŭd tīp),
The specific agglutination pattern of erythrocytes of an individual to the antisera of one blood group; for example, the ABO blood group consists of four major blood types: O, A, B, and AB. This classification depends on the presence or absence of two major antigens: A or B. Type O occurs when neither is present and type AB when both are present. The blood type is the genetic phenotype of the individual for one blood group system and may be determined using different antisera available for testing. See Blood Groups Appendix.

Patient discussion about blood type
Q. HIV - does it infect specific Blood Types? A friend of mine joined the army and they took him to an experiment and infected him with HIV. But he was not infected- he said because he has a certain blood type. Is this true?
A. HIV, as all other viruses need specific cells,s surface proteins which called receptors,in case of HIV these receptors are found in certain WBCs that known as T-helper cells which named as T4 cells. All humans have these T4 cells but some people lack the receptor that necessary for virus attachment and pentration of the cell which leeds to the inablity of the virus to cause infection and become a target for the immune system. But they c can infect other suseptable people.
Q. Is it true that people with different blood type should have different diets?
A. I myself believe that that theory was kind of "psychological" advise : if you believe on it, then you do it, then you will have positive result. But I agree with violet that there is still none appropriate study to prove that theory.
And by the way, what "eat diet according to your blood type" suggests most likely are full lists of healthy foods, so I do believe if you follow a healthy diet program (doesn't have to be blood-type-diet), you will have a healthy life indeed..
Stay healthy always..
Q. is it possible to change my blood type from ab to ab-?
A. not really no...i mean there's a possibility if you'll have bone marrow and liver transplant-More discussions about blood type
and immunologically there shouldn't be a problem, because the body will react to an addition of proteins but not the lack of them (Rh-). but i fail to see why you want to do that.
