How do you identify malaria parasites on blood smear?

How do you do a malaria smear?
Thin smears
- Place a small drop of blood on the pre-cleaned, labeled slide, near its frosted end.
- Bring another slide at a 30-45° angle up to the drop, allowing the drop to spread along the contact line of the 2 slides.
- Quickly push the upper (spreader) slide toward the unfrosted end of the lower slide.

How do you perform a blood smear?
- Place clean glass slide on a flat surface. Add one small drop of blood to one end.

- Make 2 smears, allow to air dry, and label clearly.
