A Fad - Probably Not: Blood type refers to thousands of proteins & glyco-proteins on the surface of cells, especially red blood cells. Abo and rh types refer to only the first 2 & most important (in terms of transfusion reactions) characterized historically. There are hundreds more "types", the reason blood cross-typing is always performed before transfusions. Types reflect genes - but clear basis for selecting foods.

No.: Your blood type never changes. If this appears to be the case there has been an administrative error somewhere.

No: Old methods may have shown a weak-a or a weak-b as an o, and a weak rh as negative. A few diseases produce molecules adsorbed to red cells that may change the way they type.

Very very rare: Rarely a person may acquire blood group B antigen due to colon cancer. Bone marrow transplant from a person with different blood type would change the blood type. Both of these are very rare. A more likely explanation is error in specimen labeling.
