ABSTRACT
Iron is a vital element in the human metabolism. It plays a central role in erythropoiesis and is also involved in many other intracellular processes in all the tissues of the body. Blood donation results in a substantial (200 to 250 ng) loss of iron at each donation (425 to 475 ml) with subsequent mobilization of iron from body deposits. Repetitive donations of blood my cause the depletion of iron reserves in blood donors and thus cause health disorders. Recent reports have shown that iron reserves are generally small and iron depletion is more common in blood donors than in non-donors. The high frequency of iron deficiency in blood donors reported by these studies suggests a need for more accurate studies, as measurement of hemoglobin and hematicrit alone is insufficient to identify and exclude prospective blood donors with iron deficiency but without anemia. It is important, therefore, that blood banks evaluate the risk-benefit of implanting tests to analyze organism iron reserves such as the measurement of serum ferritin of all individuals who donate more than three times per year in order to make the blood donation process safer for both donors and transfused patients.
