Ferritin - Blood Test - In-Store only


A ferritin test measures the amount of ferritin in your blood. Ferritin is a blood protein that contains iron. A ferritin test helps your doctor understand how much iron your body stores.


If a ferritin test reveals that your blood ferritin level is lower than normal, it indicates your body's iron stores are low and you have iron deficiency. As a result, you could be anemic.


If a ferritin test shows higher than normal levels, it could indicate that you have a condition that causes your body to store too much iron. It could also point to liver disease, rheumatoid arthritis, other inflammatory conditions or hyperthyroidism. Some types of cancer also can cause your blood ferritin level to be high

  • Why it's done

    If your doctor suspects you have too much or too little iron in your body, he or she might suggest a ferritin test. The test can diagnose or suggest:

    • Iron deficiency anemia
    • Hemochromatosis — a condition that causes your body to absorb too much iron from the food you eat
    • Liver disease
    • Adult Still's disease

    Your doctor might also suggest a ferritin test if you've been diagnosed with a disorder that results in too much iron in your body, such as hemochromatosis. Your doctor might use a ferritin test to monitor your condition and guide treatment.
