Conditions associated with extreme hyperferritinaemia (&gt;3000 μg/<scp>L</scp>) in adults

Abstract

Extreme hyperferritinaemia greater than 3000 μg/L is uncommon in adult patients. The highest serum ferritin values are seen in HLH, but the differential diagnosis for serum ferritin greater than 3000 μg/L remains broad with iron overload and liver disease being the most common causes.
