Ferritin Test

The Ferritin Test measures the level of ferritin molecules in the blood.

Ferritin is a protein in the body that binds to iron.  The level of ferritin correlates with the total amount of iron stored in the body.   Ferritin is low in those with iron deficiency anemia and high when levels of iron are raised.  Liver dysfunction can cause elevated ferritin levels because the liver is unable to clear it from the body.  Ferritin may also be increased when the body is inflamed or an infection is present.
