Clinical Significance

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).
