Can Ferritin Levels Indicate Inflammation in the Body?

Yes, ferritin is an acute-phase reactant that increases during inflammation, even when iron stores are normal or low. Chronic inflammatory conditions, infections, or autoimmune diseases can elevate ferritin levels, complicating the diagnosis of iron deficiency. Additional tests like C-reactive protein (CRP) or erythrocyte sedimentation rate (ESR) help differentiate inflammation from iron overload.
