Ferritin 250 μg/L: Clinical Interpretation
Direct Answer
A ferritin level of 250 μg/L is mildly elevated and most commonly reflects inflammation, liver disease, metabolic syndrome, or alcohol consumption rather than iron overload—true iron overload is unlikely unless transferrin saturation is also elevated (≥45%). 1
Understanding What Ferritin 250 Means
Ferritin at 250 μg/L falls into an intermediate zone that requires context-dependent interpretation:
- This level is below the threshold for organ damage risk (>1000 μg/L for liver complications), so there is no immediate concern for iron-related tissue injury 2, 1
- Over 90% of hyperferritinemia cases are caused by non-iron overload conditions: chronic alcohol consumption, inflammation, cell necrosis, tumors, and metabolic syndrome/NAFLD 1
- Ferritin is an acute-phase reactant that rises during inflammation, infection, and tissue damage independent of actual iron stores 1, 3
Essential Next Step: Check Transferrin Saturation
You must measure fasting transferrin saturation (TS) simultaneously with ferritin to properly interpret this result—never use ferritin alone. 1, 4
Interpretation Algorithm Based on TS:
- Iron overload is unlikely
- The elevated ferritin reflects secondary causes:
- Inflammatory conditions (acute phase response)
- Liver disease (alcoholic, viral hepatitis, NAFLD)
- Metabolic syndrome
- Malignancy
- Chronic kidney disease
- Recent infection or tissue injury
- Consider primary iron overload disorders
- Proceed with HFE genetic testing (C282Y and H63D mutations)
- Hereditary hemochromatosis becomes a diagnostic consideration
Common Clinical Scenarios at Ferritin 250
Most Likely Causes:
Metabolic syndrome/NAFLD: Ferritin elevation reflects hepatocellular injury and insulin resistance rather than iron overload 1
Chronic alcohol consumption: Increases iron absorption and causes hepatocellular injury 1
Inflammatory conditions: Any chronic inflammatory state (rheumatologic disease, chronic infection) 1, 5
Liver disease: Viral hepatitis B or C, acute hepatitis 1
Malignancy: Solid tumors or lymphomas (though typically ferritin would be higher) 5
What You Should Do Next
Immediate Workup:
- Measure fasting transferrin saturation (morning sample preferred) 1, 4
- Complete metabolic panel including ALT, AST to assess hepatocellular injury 4
- Inflammatory markers: CRP and ESR to detect occult inflammation 4
- Detailed alcohol history: Quantify weekly consumption 1
- Review medications and comorbidities that could explain elevation 1
If TS ≥45%:
- Order HFE genetic testing for C282Y and H63D mutations 2, 1, 4
- Screen first-degree relatives if hereditary hemochromatosis is confirmed 2, 4
If TS <45%:
- Treat the underlying condition, not the ferritin number itself 4
- For NAFLD: weight loss and metabolic syndrome management 4
- For inflammatory conditions: disease-specific anti-inflammatory therapy 4
- For alcohol-related: cessation counseling 1
Critical Pitfalls to Avoid
- Never diagnose iron overload based on ferritin alone without checking transferrin saturation 1, 4
- Do not assume this level requires phlebotomy—therapeutic phlebotomy is only indicated for confirmed hemochromatosis with iron overload 4
- Do not overlook common secondary causes (inflammation, liver disease, metabolic syndrome) which account for >90% of cases 1
- Do not fail to screen first-degree relatives if HFE-related hemochromatosis is ultimately confirmed 2, 4
Reassurance About Risk
- Ferritin 250 μg/L carries minimal risk of organ damage: The threshold for cirrhosis risk in hemochromatosis is >1000 μg/L, and no patients with ferritin <1000 μg/L had cirrhosis in validation studies 2, 1
- This level does not indicate need for urgent intervention unless accompanied by markedly elevated liver enzymes or other concerning features 4
Special Considerations
In Chronic Kidney Disease:
- Ferritin 250 μg/L with low TS (<20%) may represent functional iron deficiency that could respond to IV iron therapy 1
In Inflammatory Bowel Disease:
- Ferritin >100 μg/L with low TS suggests anemia of chronic disease rather than iron deficiency 1
With Joint Symptoms:
- Arthropathy occurs in 43-57% of hemochromatosis cases, so joint symptoms warrant closer evaluation for iron overload 6
