Ferritin Reference Range
These are the typical adult reference ranges used by major US labs. Your report will include the specific range used by the lab that processed your sample.
| Population | Range |
|---|---|
| Male, age 18+ | 24.0 – 336 ng/mL |
| Female, age 18+ | 11.0 – 307 ng/mL |
Reference ranges are educational. Always interpret your result with the specific range printed on your lab report and discuss anything outside the range with a clinician.
What your Ferritin result may mean
Often reflects inflammation, infection, or excess iron stores. Less commonly, liver disease.
Strongly suggests iron deficiency, even before anemia develops. Common in menstruating women, vegetarians, and athletes.
Educational only — not a diagnosis. Many factors can influence a single result. Discuss anything that concerns you with a healthcare provider.
