Clinical Significance
Most body iron is found in hemoglobin. The serum measurement of iron is useful in the differential diagnosis of anemia, iron deficiency anemia, thalassemia, possible sideroblastic anemia, and iron poisoning. Serum iron is increased in hemosiderosis, hemolytic anemias, thalassemia, sideroblastic anemias, hepatitis, acute hepatic necrosis, hemochromatosis, inappropriate iron therapy, and iron poisoning. Serum iron is decreased in cases of insufficient dietary iron, chronic blood loss, inadequate absorption of iron, impaired release of iron stores (commonly observed in inflammation), infection, and chronic diseases.
