Iron status is used in the diagnosis and management of some hematologic and hepatic conditions. In addition to serum iron levels, several tests may be ordered including UIBC, total iron binding capacity (TIBC) and ferritin. TIBC is a surrogate for transferrin and has a direct relationship to it. TIBC = (UIBC + serum iron). UIBC and TIBC are increased in low iron states such as uncomplicated anemia and decreased in high iron conditions such as hemochromatosis. The lone exception to the preceding is the case of anemia of chronic disease where the patient may be anemic but has adequate iron reserves and a low UIBC.
