While no single test is reliable to distinguish iron deficiency anemia from the anemia of<unk>  inflammation, there are sometimes some suggestive data: * In anemia of<unk>  inflammation without iron deficiency, ferritin is normal or high, reflecting the fact that iron is sequestered within cells, and ferritin is being produced as an acute phase reactant. In iron deficiency anemia ferritin is low. * Total iron-binding capacity (TIBC) is high in iron deficiency, reflecting production of more transferrin to increase iron binding; TIBC is low or normal in anemia of<unk>  inflammation.
