About this biomarker
Ferritin is the main iron storage protein in the body. Blood ferritin is often used to estimate how much stored iron is available.
Why it matters
It is a core marker in iron evaluation, though inflammation can also raise it.
What lower levels may suggest
Low ferritin usually suggests low iron stores.
What higher levels may suggest
High ferritin may reflect inflammation, liver disease, iron overload, infection, or other conditions.
Common tests
Ferritin test, iron studies, anemia workup
