What is a normal ferritin level?

The normal range for ferritin levels can vary depending on the laboratory and the population being evaluated. In general, for adults, a normal ferritin level ranges from 15 to 200 nanograms per milliliter (ng/mL) for males and 12 to 150 ng/mL for females. However, it's important to note that "normal" ranges can differ slightly between different laboratories. Ferritin levels outside the normal range may indicate underlying iron deficiency or iron overload conditions. Interpreting ferritin levels should be done in conjunction with other diagnostic tests and the individual's specific circumstances.
