Ferritin – Ferritin is the protein that stores iron in your body. It’s the best single blood marker of your iron reserves.
What Ferritin measures
Ferritin measures how much iron you have stored – low ferritin signals iron deficiency before anemia appears.
Typical ranges
Roughly 30-300 ng/mL for men and 15-200 ng/mL for women, though labs vary and clinical context matters. Reference ranges differ between laboratories and by age and sex, so always read your result against the range printed on your own report.
What high results can mean
Can reflect iron overload, inflammation, or liver issues.
What low results can mean
Indicates low iron stores and possible iron-deficiency anemia – a common cause of fatigue.
How the test is done
A blood sample; no fasting required. Ferritin rises with inflammation, so it’s read alongside other markers. At-home collection works well for this marker when the sample is processed by a certified lab.
