How do you make blood smear?

To make a blood smear, first, obtain a clean glass microscope slide and place a small drop of blood about 1-2 cm from one end. Using another slide at a 30-45 degree angle, touch the drop and then swiftly spread it across the slide with a smooth motion, creating a thin film. Allow the smear to air dry completely before staining it with a suitable dye, such as Wright's or Giemsa stain, to visualize the cells under a microscope. Finally, rinse the slide gently and let it dry again before examining it.
