A ferritin test measures the amount of ferritin in your blood. Ferritin is a blood cell protein that contains iron. A ferritin test helps your doctor understand how much iron your body is storing.
Test results generally take between 24 to 72 business hours after your specimen is collected. Ferritin is a protein in the body that binds to iron. The level of ferritin correlates with the total amount of iron stored in the body. Ferritin is low in those with iron deficiency anemia and high when levels of iron are raised. Liver dysfunction can cause elevated ferritin levels because the liver is unable to clear it from the body. Ferritin may also be increased when the body is inflamed or an infection is present.
