Your blood type is determined by specific markers, called antigens, found on the surface of your red blood cells. If you receive blood with unfamiliar antigens, your immune system may recognize it as foreign and attack the donated red blood cells, causing a potentially life-threatening transfusion reaction. The ABO and Rh systems are the two most important factors when matching blood for transfusions. For example, people with type O negative blood do not have A, B, or Rh antigens on their red blood cells, allowing it to be used in many emergency situations, which is why it is often called the universal red blood cell donor. In contrast, people with AB positive blood can receive red blood cells from any ABO and Rh blood type because they do not produce antibodies against those antigens. Before every transfusion, donated blood is carefully typed and crossmatched with the recipient’s blood to confirm compatibility. This testing helps ensure the donated blood is safe, allowing blood transfusions to replace blood lost through injury, surgery, or illness while minimizing the risk of dangerous immune reactions.
