A 45-year-old female phoned her physician and complained of fatigue, shortness of breath on exertion, and general malaise. She requested 'vitamin B12 shots' to make her feel better. The physician asked the patient to schedule an appointment so that she could determine the cause of the symptoms before offering treatment. A hemoglobin determination performed in the laboratory was 9.0 g/dL. The physician then requested additional laboratory tests, including a FBC with a peripheral blood film examination and a reticulocyte count. A. Why did the physician want the patient to come to the office before she prescribed therapy? (5 Marks) B. How do the mean cell volume and reticulocyte count help determine the classification of the anemia? (8 Marks) C. Why is the examination of the peripheral blood film important in the investigation of anemia? (7 Marks)
