Ferritin - FERR1

Ferritin is a blood protein that stores iron and releases it as needed. The serum ferritin level serves as a reliable indicator of your body’s iron reserves.

• Low ferritin typically signals iron deficiency and low iron stores, even before red blood cell changes appear.
• High ferritin may indicate iron overload (such as hemochromatosis), chronic inflammation, liver disease, or certain malignancies.

This test is commonly used to help diagnose or monitor iron deficiency, iron overload, or related conditions, and is often paired with other iron studies for full context.
