Heres an idea, why not have the option to have it listed on your drivers license next to the bit where it lists you as a donor(or not)?

If I remember my 6th form Human Bio correctly (and that was a LOT of years ago) O- they can give to anyone but any other blood type if they don't give you the same as what is already falling out of you it causes clotting - not just stop the leak clotting but stop the flow clotting.

Hmm, I was under the impression, that it more causes an immune reaction against the blood .... kinda not good when you need said blood to remain in the land of the living
... * looks it up*

from Wikipedia "If an individual is exposed to a blood group antigen that is not recognised as self, the immune system will produce antibodies that can specifically bind to that particular blood group antigen, and an immunological memory against that antigen is formed. The individual will have become sensitized to that blood group antigen. These antibodies can bind to antigens on the surface of transfused red blood cells (or other tissue cells), often leading to destruction of the cells by recruitment of other components of the immune system. When IgM antibodies bind to the transfused cells, the transfused cells can clump. It is vital that compatible blood is selected for transfusions and that compatible tissue is selected for organ transplantation. Transfusion reactions involving minor antigens or weak antibodies may lead to minor problems. However, more serious incompatibilities can lead to a more vigorous immune response with massive RBC destruction, low blood pressure, and even death."


*edit* then again it helps if i read the rest of the thread
