Iron Saturation is done when your doctor suspects you may have too much or too little iron in your body because of a variety of conditions. Iron Saturation is part of the iron studies that is done when somoeone is anaemic. These may include: Iron, Ferritin, Total Iron Binding Capacity (TIBC), and Percent Saturation of Transferrin.
These tests measure different aspects of the body’s iron storage and usage. They are ordered to help determine whether an iron deficiency is causing and/or exacerbating a patient’s anaemia.
