You are a lab technician in a hospital. The doctor asks you to make a slide of your patient’s blood to examine his white blood cells (WBCs). You know that red blood cells (RBCs) are far more common that WBCs and want to eliminate any interference from RBC’s in the slide. Fortunately you also know WBCs are more pliable and less likely to lyse than RBCs. You are a lab technician in a hospital.
