Ferritin is a protein that stores iron and releases it when needed.

Serum ferritin levels reflect the body’s iron reserves.

Clinical uses include:

Diagnosing iron deficiency anemia.

Detecting iron overload disorders such as hemochromatosis.

Monitoring patients with chronic diseases that affect iron metabolism.

Assessing iron status in individuals with unexplained fatigue, weakness, or pallor.

The test is performed using a blood sample.

Analyte: Serum ferritin concentration.

Normal Range (approximate, varies by lab):

Men: 24 – 336 ng/mL

Women: 11 – 307 ng/mL

Abnormal Findings:

Low ferritin: Indicates iron deficiency anemia or chronic blood loss.

High ferritin: Suggests iron overload, liver disease, chronic inflammation, or certain cancers.

Clinical Use:

Provides a reliable measure of iron storage status.

Helps differentiate between types of anemia.

Guides treatment in iron deficiency or overload conditions.
