Ferritin is the primary biomarker used to quantify total body iron storage. It is useful for differentiating iron deficiency anemia from anemia of chronic disease, identifying iron overload disorders e.g. hemochromatosis, and evaluating systemic inflammation, as ferritin also acts as an acute-phase protein.

Ferritin results should be interpreted alongside C-Reactive Protein (CRP; Test code: 11037), to aid with interpretation.
