If the ferritin level is low, there is a risk for lack of iron, which could lead to anemia. If ferritin is high, there is iron in excess or else there is an acute inflammatory reaction in which ferritin is mobilized without iron excess. For example, ferritins may be high in infection without signaling body iron overload. Ferritin is also used as a marker for iron overload disorders, such as hemochromatosis or hemosiderosis. Recent research has shown that H-Ferritin from melanoma cells may suppress immune responses [5][6][7].
