Ferritin

Ferritin is the main iron storage complex and is present mostly in the liver, but also in the bone marrow, spleen, and muscles. Small amounts of ferritin also circulate in the blood. The ferritin concentration within the blood stream reflects the amount of iron stored in your body.

Ferritin may be elevated due to hemochromatosis and other genetic conditions, inflammation, liver damage, haemolytic or sideroblastic anaemia. May be decreased due to poor intake, poor absorption, chronic blood loss, chronic disease or infection, progesterone birth control pills.
