Several stains are used to highlight different components of blood cells: - Wright's Stain: Commonly used for routine blood smears, it provides good differentiation between cell types. - Giemsa Stain: Often used in combination with Wright's stain, it is particularly useful for detecting certain parasites like Plasmodium (malaria). - Leishman's Stain: Another option for staining blood smears, providing good contrast for cellular components.
