typing

blood typing (typing of blood) determining the character of the blood on the basis of agglutinogens in the erythrocytes; see also blood group.
phage typing characterization of bacteria, extending to strain differences, by demonstration of susceptibility to one or more races (a spectrum) of bacteriophage; widely applied to staphylococci, typhoid bacilli, and other organisms for epidemiological purposes.
tissue typing identification of the human leukocyte antigens of the donor and recipient of a transplant or transfusion; see also tissue typing.

Patient discussion about blood typing

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-

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.
