What Is a Ferritin Blood Test?
Ferritin blood test is the blood test to determine the levels of body iron and iron deficiency.
- A ferritin test is a laboratory blood test that measures the amount of ferritin in a person's bloodstream.
- Ferritin is the major iron storage protein in the body, so the ferritin test is ordered as an indirect way to measure the iron stores in the body.
- The ferritin test is often ordered as part of a panel of tests that examine the levels of body iron and the effects of abnormalities in iron storage.
- It may be ordered together with an iron level, a total iron-binding capacity test, or blood cell counts.
