If you are injured or have certain illness that needs blood they may receive a blood transfusion to replace lost blood, but before transfusion heath care workers must identify patients blood type. If the wrong blood type is given the persons, blood clumps and blocks tiny capillaries, oxygen does not get to cells, and without oxygen, cells die. If you are severely injured and need blood it saves time if they know your blood type. It also is handy for DNA purposes.
