MyBody-X angle on Ferritin Männer

Ferritin is a key biomarker for body iron stores. In men, interpretation is more nuanced than in women because men lack menstrual iron losses. Elevated ferritin may indicate hereditary hemochromatosis (iron overload), which manifests earlier and more severely in men. HFE genotyping (C282Y, H63D) is the gold standard. However, ferritin is also an acute-phase reactant: inflammation, infection, liver disease, or metabolic syndrome can raise ferritin without true iron overload. Low ferritin reliably indicates iron deficiency, which is less common in men but may result from blood loss (e.g., gastrointestinal) or malabsorption. MyBody-X tests can measure ferritin, but a single value is insufficient for diagnosis. Clinical workup with transferrin saturation, CRP, and possibly HFE analysis is required. Evidence: well-established (human-moderate).
