Test Code: 4020

CPT: 82728
Tests Included Ferritin
Use Ferritin concentrations are directly proportional to the total iron stores in the body the test is used to assess the iron stores in the body.1,2,3 Often orded in conjuction with an Iron and TIBC test.
Clinical Utility Ferritin the major iron storage protein for the body. ferritin is a constituent of all normal human serum iron deficiency anemia have serum ferritin levels approximately one tenth of normal subjects In both adults and children, chronic inflammation results in a disproportionate increase in ferritin levels in relation to iron reserves. Elevated ferritin levels also are observed in acute and chronic liver disease, chronic renal failure and in some types of neoplastic disease
