A small amount is found in plasma and serum, which is a reflection of iron stores in healthy individuals. A low serum ferritin concentration is usually regarded as an indicator of iron depletion, although the interpretation of normal or high serum ferritin values is challenging in the presence of acute or chronic inflammatory processes, as ferritin is increased in iron overload states and inflammation.
