Which area of a blood smear is preferred for evaluating cell morphology and performing a differential count, and why? What morphologic artifacts are commonly seen when smears are made from aged or improperly stored blood samples? Explain how these artifacts can affect interpretation. Why should the feathered edge be examined before performing a differential count? Resources: Blood Smear Evaluation Red Blood Cells
