NCIt definition : Geimsa is a polychromatic stain that permits the differentiation of cells present
in hematopoietic tissues and for the demonstration of certain microorganisms. It is
used for the detection of helicobacter pylori. The H. pylori and nuclei stain dark
blue and cytoplasm stain pink with this stain (From BioGenex).;
Alternative definition : CDISC: A microscopy staining method that is a combination of the Wright and Giemsa
staining protocols and utilizes the Romanowsky stains, which are mixtures of eosin
and thiazine dyes such as methylene blue. It produces darker blue and magenta shades
than the giemsa stain alone, which may provide better contrast in microscopy.;
