Ferritin

Test information: Ferritin is the major intracellular iron storage protein in mammals, and it's measurement offers the best non-invasive test for iron deficiency. Serum ferritin has been shown to correlate well with total body stores in normal subjects and in patients with iron deficiency or transfusion iron overloads, and is thus considered to be a satisfactory index of body iron status. Serum ferritin concentrations are high at birth, but fall during the first few months and remain low in childhood. In healthy adults the level varies with age and gender.
