Decreased serum ferritin UMLS:C0241012 Low ferritin level Decreased plasma ferritin Ferritin levels measured in serum usually have a direct correlation with the total amount of iron stored in the body, but ferritin levels may also be increased with anemia of chronic disease or in the course of an acute phase reaction.
