Study Notes
Blood Film Preparation for Parasite Detection
- Thin blood films are used to detect parasites within blood cells, while thick blood films are used to detect parasites in larger quantities of blood.
Parasite Detection in Blood
- The parasite detected extracellularly in blood is Trypanosoma.
- The parasite detected intracellularly in blood is Plasmodium.
Primary Purpose of Blood Examination
- The primary purpose of blood examination for parasitic diseases is to diagnose and identify the type of parasite present.
Blood Film Preparation Method
- The method that involves placing a small drop of blood on a pre-cleaned slide and allowing it to spread by bringing another slide at an angle is called the "slide-and-spread" or "push" method, used to prepare thin blood films.
