Preferred specimen is primary serum sample contained in properly centrifuged gel barrier tube (not necessary to transfer serum to separate tube) - Methodology:
Electrochemiluminescent Immunoassay (ECLIA) - Use:
Evaluate microcytic anemia, iron storage diseases, and iron metabolism - Clinical Significance:
Ferritin is found in serum in low concentrations and is directly proportional to the body's iron stores. In general, variations in total body iron stores will be reflected in the serum ferritin level. Serum ferritin levels are very helpful in the diagnosis of iron deficiency anemia, anemia of chronic infection, thalassemia, and hemochromatosis. Serum ferritin levels, however, can be nonspecifically elevated in patients with inflammation and or liver disease, regardless of iron stores. This is attributed to hepatocellular leakage of ferritin from damaged cells. - Reference Range:
