What does it measure?
An indicator of the body's iron stores. Low ferritin suggests depleted stores.
Relationship to nutrition
Red meat, legumes and dark leafy greens provide iron; plant iron is absorbed better with vitamin C and worse with tea and coffee. After bariatric surgery iron absorption can fall, so it is monitored regularly.
Before the test
- Ferritin can be falsely high during infection or inflammation; tell your doctor if you were unwell.
