    Ferritin

    What Affects the Test

    Reasons you may not be able to have the test or why the results may not be helpful include:

    • Having a blood transfusion in the past 4 months.
    • Being a female athlete whose amount of activity has changed her menstrual cycle.
    • Having conditions that cause inflammation in the body, such as from illness or from a surgery.
    • Having a radioactive scan in the past 3 days.
    • Taking medicines, such as birth control pills and antithyroid medicines.
    • Age. Older adults may have a higher ferritin value.
    • Eating a diet high in red meats.

    What To Think About

    • A ferritin test is often done with other tests to check the amount of iron in the blood, especially the iron and iron-binding capacity levels. To learn more, see the topic Iron (Fe).
    • A bone marrow biopsy camera.gif can check the amount of iron stored in the bone marrow. To learn more, see the topic Bone Marrow Aspiration and Biopsy.
    • Because inflammation in the body can cause high ferritin levels, a test result that is slightly high does not always mean a buildup of iron (hemochromatosis) is present.
