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.
Serum iron, total iron-binding capacity (TIBC) , and/or transferrin tests are usually ordered together and, subsequantly, the transferrin saturation can be determined and used to assess how much iron is being carried in the blood. A ferritin test may also be used to evaluate a person's current iron stores.hese tests are used together to detect and help diagnose iron deficiency or iron overload. In people with anemia, these tests can help determine whether the condition is due to iron deficiency or another cause, such as chronic blood loss or some other illness.
