  1. How to look at A peripheral blood smear

  2. Low Power 1- Scan the slide under low power (10x) 2- Find a good area 3- Evaluate red cell distribution 4- Evaluate the white count 1 WBC = 1000-2000mm3

  3. Too thick area Red cells appear as; • microcyte • hypochrome • rouleaux

  4. Too thick area

  5. Too thin Red cells appear as • macrocyte • spherocyte • poikilocyte

  6. Too thin area

  7. Good area

  8. What are you looking for at a peripheral smear (Oil immersion) • Red cell morphology • Platelet number and morphology • WBC differential and morphology • Blood parasite
