What it measures
Ferritin is a protein that stores iron. The blood test helps a clinician assess your iron stores.
Why it may be considered
It may be considered when investigating iron deficiency or iron overload, together with your history and other tests.
What affects interpretation
Ferritin can also rise with inflammation or other conditions. Do not start iron supplements based on a single result without discussing the reason and appropriate follow up.
Laboratory reference ranges depend on the test and laboratory. This glossary does not interpret your results or imply that Lola orders this test. Your provider will determine what is relevant to your care.
