Ferritin Evaluator
Metabolic Relevance
Ferritin reflects iron stores but also acts as an acute-phase protein during inflammation. Low levels suggest iron deficiency (fatigue, hair loss); high levels may indicate iron overload or chronic inflammation. Always interpret with CRP for accurate assessment.
Recommended testing frequency:
Annually, or every 3-6 months if managing iron deficiency or overload
Did you know?
Ferritin is an "acute-phase protein" — it rises during inflammation, independent of true iron stores. That's why checking CRP alongside ferritin is essential for accurate interpretation.
Optimal ranges differ by gender: 50-150 ng/mL for men, 30-100 ng/mL for women. Menstruating women have lower optimal ranges due to regular iron loss.
