Blood Compatability

Blood compatibility refers to how well a person's blood type matches another's, particularly during transfusions or organ transplants. Blood types are categorized based on specific markers called antigens and antibodies. The main blood groups are A, B, AB, and O, with each having a positive or negative Rh factor. For safe transfusions, it’s crucial to match donor and recipient blood types to prevent immune reactions, where the body rejects incompatible blood. Understanding blood compatibility helps ensure safe medical procedures and treatments, preventing serious complications that can arise from mismatched blood.
