Iron tests measure different substances in the blood to check iron levels in your body. Iron is a mineral that your body needs for growth and development. Your body uses iron to make hemoglobin, a protein in red blood cells. It carries oxygen from the lungs to all parts of the body, Iron is also important for healthy muscles, bone marrow, and organ function.

Normal range
- Normal
- 200–400 mg/dL (varies by lab) ABIM 200–400 · ARUP 200–360 · Mayo 200–360 mg/dL
These labs do not agree: the published adult ranges differ by up to 11%, so the same result can read as normal at one lab and be flagged at another — ABIM 200–400 · ARUP 200–360 · Mayo 200–360 mg/dL. Both are real published values, shown as each lab states them.
Ranges from ARUP Laboratories Test Directory, American Board of Internal Medicine (Laboratory Test Reference Ranges), Mayo Clinic Laboratories (Test Catalog).
