A blood transfusion is a common, safe medical procedure in which healthy donor blood is given to you through an intravenous, or IV line inserted in one of your blood vessels. Blood transfusions replace blood that is lost through surgery or injury. This treatment also provides blood if your body is not making blood properly on its own.
