A Ferritin test is a blood test that measures the levels of ferritin in the blood. Ferritin is a protein that stores iron in the body and helps indicate the body's iron stores. This test is often used to diagnose conditions such as iron deficiency anemia, hemochromatosis (excess iron storage), or other iron-related disorders. High or low ferritin levels can indicate various health conditions and may require further evaluation and treatment.
