Blood component therapy

Abstract

Blood components therapy is a medical procedure in which blood is transferred from one person (the donor) to another person (the recipient). Blood transfusions can be used to replace blood that has been lost due to injury or surgery, or to treat certain medical conditions that affect the production or function of blood cells. Before a blood transfusion, the recipient's blood type and the donor's blood type are matched to ensure compatibility. Blood types are classified as A, B, AB, or O, and are further characterized by the presence or absence of certain antigens on the surface of red blood cells. If the recipient receives blood with antigens that their body recognizes as foreign, it can trigger an immune response that can be life-threatening.
