Decreased circulating ferritin concentration

What it means

Abnormally reduced concentration of ferritin, a ubiquitous intracellular protein that stores iron, in the blood.

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.
