A ferritin level above 300 ng/mL with no inflammatory markers may suggest which condition?

• A. Iron overload (hemochromatosis)
• B. Acute infection
• C. Iron deficiency
• D. Anemia of chronic disease

Answer: (A)

Ferritin reflects how much iron is stored in the body, and it also rises with inflammation. When ferritin is above 300 ng/mL in the absence of inflammatory markers, the most likely explanation is iron overload from hemochromatosis—an inherited condition where excessive iron absorption leads to high iron stores. Over time, this excess iron can deposit in organs like the liver, heart, and pancreas and cause damage if not managed. In contrast, an acute infection typically brings up inflammatory markers along with ferritin as part of the inflammatory response, so this pattern wouldn’t fit. Iron deficiency would usually show a low ferritin level, not a high one. Anemia of chronic disease can raise ferritin because of inflammation, but that would generally be accompanied by inflammatory markers; without those markers, that diagnosis is less likely.
