Ferritin · high result

What does a high Ferritin mean?

Short answer

Ferritin rises with iron overload, but far more often with inflammation, infection, liver disease, heavy alcohol use, obesity and metabolic syndrome, because ferritin is also an acute-phase protein. Transferrin saturation is the test that separates true iron overload (saturation high) from inflammation (saturation normal or low). Hereditary hemochromatosis is the important cause not to miss.

What is the normal range for Ferritin?

  • Male, age 18+: 24.0 – 336 ng/mL
  • Female, age 18+: 11.0 – 307 ng/mL

Often reflects inflammation, infection, or excess iron stores. Less commonly, liver disease.

What are the common causes of high Ferritin?

  1. Inflammation or infection (including a recent cold)
  2. Fatty liver, alcohol use, other liver disease
  3. Metabolic syndrome, obesity, type 2 diabetes
  4. Hereditary hemochromatosis or transfusion-related iron overload
  5. Hyperthyroidism, some cancers and blood disorders
  6. Iron supplements or infusions

What symptoms go with high Ferritin?

  • Usually none from the ferritin itself
  • Joint pain, fatigue, bronze skin, liver enlargement in true overload

What do clinicians usually check next?

  • Iron with TIBC and transferrin saturation — saturation above about 45% points to overload
  • CRP and liver enzymes to look for inflammation and liver disease
  • HFE gene testing when saturation is high
  • Repeat ferritin when well if a recent illness could explain it

Follow-up tests available at TestWell: Transferrin ($23.99), C-Reactive Protein (CRP) ($26.99).

Ferritin refills slowly. When treating iron deficiency, hemoglobin usually improves within a few weeks, but ferritin needs roughly 3 months of consistent iron before a recheck can confirm stores have recovered (British Society of Gastroenterology guidance). Because ferritin also rises with inflammation, a result drawn during or just after an illness can read falsely reassuring — retest once you're well.

How do you recheck Ferritin?

Prices are cash-pay; every order adds one $6 lab processing fee. Physician authorization is included; no insurance or referral needed.

Common questions

My ferritin is 400 — do I have hemochromatosis?

Not necessarily. Most ferritin in that range is inflammation, liver or metabolic-related. A transferrin saturation under 45% makes hemochromatosis unlikely; above it, genetic testing is the next step.
