Wright stain is commonly used to stain which type of specimen?

• A. Blood Smears
• B. Bone Tissue
• C. Nervous Tissue
• D. Connective Tissue

Answer: (A)

Wright stain is a polychromatic stain used primarily on peripheral blood smears. It dyes different cellular components with acidic and basic dyes, so red blood cells, various white blood cells, and platelets take on distinct colors. This contrast lets you identify cell types and examine their morphology, which is essential for doing white blood cell differentials and spotting abnormalities like infections, anemia, or leukemias. Other tissues like bone, nervous, or connective tissue rely on different stains (such as H&E or specialized stains) to reveal their structures, so Wright stain is best known for staining blood smears.
