Ferritin is a protein that contains iron and is the primary form of iron stored inside of cells. This test measures the amount of ferritin in the blood.

Normal value range is:
Male: 12 to 300 nanograms per millilter (ng/mL)
Female: 12 to 150 ng/mL

Iron deficiency: The serum iron level continues to decrease and transferrin and TIBC and UIBC increase. As this stage progresses, fewer and smaller red blood cells are produced, eventually resulting in iron deficiency anemia. Transferrin saturation is decreased with iron deficiency.
Iron overload: it is likely that the person has iron poisoning. Iron poisoning occurs when a large dose of iron is taken all at once or over a short period of time. In some cases, acute iron poisoning can be fatal. In patients with chronic iron overload, ferritin levels increase.
