Product Description:

Wright stain is a commonly used hematological stain. This stain is used in blood smear preparations and has also been described in the staining of microorganisms.

Applications:

It is used primarily to stain peripheral blood smears and bone marrow aspirates which are examined under a light microscope. 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.
