CASE STUDY An 80 year old man is seen for an annual physical examination. He complains of shortness of breath on exertion and is often tired. His stool is black. Laboratory data are: Haemoglobin: 8.2 g/dL Haematocrit: 30% White cell count: 4.2 x 109/L White cell differential: Neutrophils: 60% Lymphocytes: 31% Monocytes: 7% Eosinophils: 2% Basophils: 0% Red cell count: 4.0 x 1012/L RDW: 20% Platelet count: 400 x 10°/L Reticulocyte count: 1.2% Stool occult blood: Positive QUESTIONS 1. What is this patient's MCV? Show calculation With reference to the MCV normal range, comment on the MCV 2. obtained in 1A above. 3. How would you classify this anaemia morphologically?
