Giemsa is a polychromatic stain. Giema’s unique formulation and ability to stain nuclear membranes, chromatin, and cytoplasmic elements make it a very versatile stain. It is suitable for use in a diverse range of application including histological biopsies, clinical cytology specimens, bacteriology, and tumor samples. It is also used in hematology for blood and bone marrow specimens.

Giemsa stain is widely used to detect the presence of microorganisms in all types of tissues including the detection of Helicobacter pylori in the diagnosis of chronic gastritis or gastric ulcers.
