The serum ferritin level is the most effective way to diagnosis iron deficiency anemia. When the serum ferritin is less than 15 ng per mL (15 Î¼g per L), iron deficiency is virtually certain (Table 5 14â17). Iron deficiency is unlikely if the serum ferritin level is greater than 100 ng mL (100 Î¼g per L). Although ferritin levels between 15 and 100 ng per mL are moderately predictive of iron deficiency anemia, patients with levels in this range may have iron deficiency anemia, anemia of chronic disease, or both.
