Key questions to ask when evaluating the patient:
(1) Does the patient have a history of microcytic, normocytic or macrocytic anemia?
(2) If so, has the patient recently received specific therapy for the anemia?
(3) What is the patient's reticulocyte count?
(4) Has the patient been recently transfused?
(5) Is there evidence of a hemolytic anemia?
