Hancock, a 65-year-old white male, was seen in triage with complaints of fatigue, malaise, anorexia, and hemoptysis of recent onset. A complete blood count (CBC) was ordered and revealed anemia and a shift to the left in granulocytes. Hematopoietic cells showed dysplastic features.
Consider diagnostic probabilities and reflex testing that could provide differential diagnostic information.
The results of the CBC on Hancock were:
The neutrophilic cells show marked hyposegmentation and hypogranulation. Red blood cell (RBC) morphology includes anisocytosis and poikilocytosis, teardrop cells, ovalocytes, and schistocytes.
Calculate the mean cell volume (MCV). What peripheral blood findings are helpful to rule out megaloblastic anemia?
