Diagnostic Approach and Management of Elevated Ferritin Levels

Initial Evaluation and Risk Stratification

The American Association for the Study of Liver Diseases recommends measuring both serum ferritin and transferrin saturation together for proper evaluation, as relying on a single test is insufficient 1
If either test is abnormal (transferrin saturation ≥45% or ferritin above the upper limit of normal), HFE mutation analysis should be performed, according to the American Association for the Study of Liver Diseases 1
The European Association for the Study of the Liver suggests investigating common causes of non-iron overload hyperferritinemia, including chronic alcohol consumption, inflammation, cell necrosis, malignancy, and non-alcoholic fatty liver disease, before pursuing genetic testing 3
The American Gastroenterological Association recommends checking for malignancy, including evaluating ESR and considering imaging, in cases of unexplained elevated ferritin 4

Ferritin levels can be used to stratify risk, with levels <1000 μg/L indicating low risk of cirrhosis and levels >1000 μg/L indicating higher risk, particularly in C282Y homozygotes with elevated liver enzymes and platelet count <200,000, as recommended by the American Association for the Study of Liver Diseases 1, 2
The European Association for the Study of the Liver recommends assessing for liver fibrosis using non-invasive methods like transient elastography in patients with HFE-related hemochromatosis 5

The American Association for the Study of Liver Diseases recommends therapeutic phlebotomy as the mainstay of treatment for confirmed iron overload, with monitoring of serum ferritin levels to guide therapy 1, 2
For C282Y homozygotes with elevated ferritin, the American Association for the Study of Liver Diseases recommends initiating therapeutic phlebotomy 1
The European Association for the Study of the Liver suggests addressing underlying causes of secondary iron overload, such as alcohol cessation or weight loss for metabolic syndrome 3

The American Association for the Study of Liver Diseases recommends screening for all first-degree relatives of patients with confirmed HFE-related hemochromatosis 1, 2
For children of an identified proband, the American Association for the Study of Liver Diseases recommends HFE testing of the other parent 1
The American Association for the Study of Liver Diseases recommends annual follow-up with iron studies for C282Y homozygotes with normal ferritin 2
