[Hyperferritinemia].

Many causes provoke elevated serum ferritin levels including not only iron overload, but also many pathological situations where hyperferritinemia or modified isoferritin profiles have no direct relationship with body iron stores. There are five general categories of hyperferritinemia: hemochromatosis, inflammatory syndromes, cytolysis, hemophagocytosis, Still's disease, and other etiologies.
