  • How long does blood transfusion last in the system of the recipient?

    The normal daily production of red blood cells (RBC) in a healthy adult is about 0.25 mL/kg and the average lifespan of the cells is about 120 days, whereas that of transfused RBCs is about 50–60 days and can be significantly shorter in the presence of factors reducing their survival.
