Prospective study of 259 patients aged 65+ diagnosed with iron deficiency anemia. Two hematologists interpreted the results. Since data was generated from the same cohort of patients, the authors used correction factor in generating the ROC curves. Serum ferritin was shown to be the most valuable test for confirming or negating iron deficiency anemia.
