Useful in the diagnosis of hypochromic, microcytic anemias. Decreased in iron deficiency anemia and increased in iron overload.
Ferritin is a protein found in the blood which carries iron. Like TIBC/UIBC, and transferrin saturation, it can tell us how much iron is stored in the body. The higher the level within a health screening, the greater the amount of iron stored. This test can be used to detect iron deficiency, and also conditions of iron excess (such as haemochromatosis). Ferritin can also be raised if inflammation is present in the body somewhere.
