What is wright stain?

Wright stain is a commonly used histological stain that is used to differentiate blood cells in a blood smear, bone marrow smear, and other tissue specimens. It was first developed by James Homer Wright in 1902.

The Wright stain is a multichromatic stain that contains a mixture of eosin and methylene blue dyes, which stain acidic and basic structures in the cell, respectively. This stain allows for the visualization of different types of blood cells, such as red blood cells, white blood cells, and platelets.

Wright stain is often used in conjunction with a Giemsa stain, which enhances the visualization of certain cellular components. The combination of these two stains is known as the Wright-Giemsa stain.

This stain is widely used in clinical laboratories and in research settings for the identification and classification of blood cells and various cellular components. It provides detailed information about the morphology and characteristics of blood cells, which can help in the diagnosis of various blood disorders and diseases.
