Wright Giemsa Stains

Wright Giemsa Stains

Wright and Giemsa stains are Romanowsky stains used to stain
peripheral blood and bone marrow smears. The most important components
of these stains are oxidized methylene blue, azure B and eosin Y dyes.
The eosin Y dye stains the cytoplasm of cells an orange to pink color.
The methylene blue and azure B dyes stain the nucleus varying shades
of blue to purple. Romanowsky stains are used to perform differential
white blood cell counts and to study red blood cell morphology.
Abnormal granulocyte, lymphocyte or monocyte cell counts may be used
to facilitate the diagnosis of diseases such as leukemia or bacterial
infections.
