Serum ferritin level
Male: 12-300 ng/mL
Female: 12-150 ng/mL
Note: ng/ml = nanograms per milliliter
The lower the ferritin level, even within the "normal" range, the more likely it is that the patient does not have enough iron.
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
The examples above show the common measurements for results for these tests. Some laboratories use different measurements or may test different specimens.
Any inflammatory disorder can raise the ferritin level.
Higher-than-normal ferritin levels may be due to:
