What is a ferritin test?
A ferritin test is a blood test that measures the amount of bloodstream
ferritin in the laboratory. Ferritin is the major iron storage protein in the
body, so the ferritin test is ordered as an indirect way to quantitate 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.
