Test Name: Giemsa

Methodology: Special Stains

Test Description

Giemsa Stain Kit is typically used to identify hematopoietic cells (i.e. mast cells, basophils, polymorphoncuclear leucocytes, etc.) in tissue sections on the Artisan™ Link and Artisan™ Link Pro Staining Systems. In tissue specimens it will stain mast cells, which may be useful in the identification of mast cell tumors. Although Giemsa stains are frequently used to study bone marrow specimens as an aid in assessment of blood disorders, this Giemsa Stain Kit is not designed for this application. The tissue elements are stained as follows: Mast cell granules: purple, basophils: purple, eosinophils: bright pink and lymphocytes: blue. This stain is not recommended for cytology specimens or bone marrow smears.
