Ferritin levels between 12 and 300 nanograms per milliliter of blood are normal in men, while readings between 12 and 150 nanograms are acceptable for women, according to MedicineNet.com. Ferritin the body's major iron storage protein and measured through a simple blood test.
Most ferratin is found in the liver, spleen, skeletal muscles and bone marrow; the small amount found in the blood indicates how much iron the body is storing.

Low levels of ferritin usually suggest an iron deficiency, which may lead to anemia.
