Reference Notes and Guidelines

Ferritin is most useful for the diagnosis of iron deficiency and iron overload conditions. It is also useful in differentiating microcytosis in red blood cells due to iron deficiency from microcytosis due to thalassemia minor. In hemochromatosis or iron overload, very high values (> 1000 ng/mL) are typically found. If malignant, hepatitic or other chronic disease states are present, the Ferritin test may not be of value in evaluating iron deficiency as values may be elevated.
