typing [tīp´ing]

in transplantation immunology, a method of measuring the degree of organ, solid tissue, or blood compatibility between two individuals, in which specific histocompatibility antigens (such as those on leukocytes or erythrocytes) are detected by means of suitable isoimmune antisera.

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. I find it hard to believe the army infected any one with HIV. But that's a different story. Blood types differ from one another by their red blood cells proteins. HIV infects white blood cells .there is no connection between blood type and a cure for HIV. If there was- you’ve heard about it by now…

Q. Is it true that people with different blood type should have different diets?

A. There were plenty of suggestions on changing your diet according to your blood type, however none of them were proved in a proper double-blinded randomized control trial in scientific medicine and therefore it is still yet another theory.

Q. Do all cancer types involve tumors? If so than having leukemia means you have tumors in your blood?

A. cancer is human cells that are mutated and lost control on their proliferating state. they just multiply and multiply without any regulation. blood cells are not attached so they don't form a "tumor" (in Latin means- a bump)if becoming cancerous.
