General description

Giemsa stain is a versatile differential stain that is widely used in hematology for blood and bone marrow specimens, clinical cytology specimens, bacteriology, histological biopsies, and tumor samples. Giemsa’s staining solution is composed of methylene blue, azure, and eosin. It is a major histological stain due to its unique staining of chromatin, nuclear membranes, and cytoplasmic elements. The stain is frequently used in combination with other dye solutions: May-Grünwald’s solution for Pappenheim (MGG) and Wright-Giemsa.

Application

Giemsa stain has been used for the staining of cells and blood films.
