A Iron & Total Iron Binding Capacity (TIBC) test is a blood test that measures the levels of iron and the capacity of a protein called transferrin to bind and transport iron in the blood. Iron is an essential mineral that is necessary for the production of red blood cells and for various bodily functions. The TIBC test helps in the diagnosis of iron deficiency or excess iron in the body, as well as conditions such as anemia, hemochromatosis, and other disorders affecting iron levels in the blood.
