Blood Typing

Blood typing is the process of determining a person's blood group based on the presence or absence of specific proteins, called antigens, on the surface of red blood cells. The main blood types are A, B, AB, and O, which can also be classified as Rh-positive or Rh-negative, depending on another antigen. This classification is crucial for safe blood transfusions, organ transplants, and pregnancy care, as incompatible blood types can trigger harmful immune reactions. Understanding blood types helps ensure patients receive compatible blood and can provide crucial information in medical emergencies.
