What Is the Normal Range for a Ferritin Test?

The normal range for ferritin levels depends on age, sex, and laboratory standards. Generally: Men: 24–336 ng/mL Women: 11–307 ng/mL Children: 7–140 ng/mL Values outside these ranges may indicate iron deficiency, iron overload, or underlying health conditions. It is important to interpret ferritin levels in conjunction with other tests, like serum iron and transferrin saturation, for accurate diagnosis. Factors like inflammation or chronic diseases may also influence ferritin levels without reflecting actual iron stores.
