Blood Transfusion Reactions

Blood transfusion reactions occur when the immune system responds negatively to transfused blood. This can happen if the recipient's immune system identifies donor red blood cells as foreign, leading to symptoms like fever, chills, rash, or back pain. Reactions range from mild to severe, including allergic responses or, in rare cases, a potentially life-threatening hemolytic reaction where red blood cells are destroyed. Proper blood matching, testing, and monitoring during transfusions help prevent these reactions, ensuring safety and compatibility between donor blood and the recipient.
