Ferritin Elevation After Trauma

Understanding Ferritin as an Acute Phase Reactant

• Ferritin behaves as an acute phase reactant during inflammation and trauma, which is the mechanism behind its elevation after fractures, as noted by the American Journal of Kidney Diseases 1, 2
• The elevation does not necessarily represent true iron overload, but rather reflects the inflammatory response to tissue injury, according to the American Journal of Kidney Diseases 1, 2

Clinical Implications

• When evaluating elevated ferritin in the context of recent fracture or surgery, consider it an inflammatory marker rather than evidence of iron overload, as recommended by the American Journal of Kidney Diseases 1, 2
• Inflammatory iron block typically shows abrupt ferritin increase with sudden drop in transferrin saturation, as described by the American Journal of Kidney Diseases 1, 2
• Do not initiate iron chelation or therapeutic phlebotomy for transiently elevated ferritin in the post-fracture period, as this represents appropriate physiologic response to trauma rather than pathologic iron accumulation, as stated by the American Journal of Hematology and the American Journal of Kidney Diseases 3, 1
