What it generally measures
Labs measure the concentration of ferritin, a protein that stores iron, in the blood.
Common units on reports: ng/mL

Ferritin is usually reviewed together with iron, TIBC, and transferrin saturation as a group, since ferritin alone can also rise with inflammation unrelated to iron stores.
