Why is my blood type important?

Everyone’s blood contains the same basic stuff, but mixed in with that stuff are ‘’antigens’’. These special proteins act like an ID tag for a person’s own and not a foreign invader. Antigen combinations make different blood types – eight in all – which are passed along from parent to child just like eye color and other genetic traits. If you get in an accident and lose a lot of blood (or get sick and need a fresh supply), you’ll have to go to the hospital to get a ‘’transfusion’’ of someone else’s red stuff. Transfusions are simple procedures and the most common type of hospital procedure but they always start with the doctor determining the patient’s blood type. If you get a transfusion of the wrong type, your immune system will think it’s an infection and go on the attack!
