Description:
Composed of iron and protein, Ferritin is a storehouse for iron in the body. The ferritin test is ordered to assess a person's iron stores in the body. The test is sometimes ordered along with an iron test and a TIBC to detect the presence and severity of iron deficiency or iron overload. In the early stages of anemia, the iron levels may be normal but the stored iron is being depleted and the ferritin level decreases. In iron overload, the ferritin level increases.
