Prepare the Giemsa working solution before staining blood film and use it within 15 minutes of preparation. Photomicrograph of a Wright-Giemsa-stained peripheral blood smear illustrating several stages of Plasmodium species. May-Grunwald Giemsa or Wright-Giemsa stain can also be used. Giemsa stain is used to identify chromosome aberration by staining the chromosomes and wright stain is used to identify the different blood cell types. To accurately prepare the Giemsa stain stock solution, To differentiate blood cells nuclei from the cytoplasm, Like any type of Romanowsky stains, it composed of both the Acidic and Basic dyes, in relation to affinities of acidity and basicity for, Malaria, spirochetes and other blood parasites. Both azure and eosin are types of acidic dye that can leave varying degrees of staining on the fundamental components of cells, such as the cytoplasm and granules. 3. The manual protocol, starting protocol (ie, manufacturers), and the final protocol for blood smears and bone marrow slides can be found in Table 1. These are neutral stains made up of a mixture of oxidized methylene blue, azure, and Eosin Y and they performed on an air-dried slide that is post-fixed with methanol. WebFor more than a century, Giemsa stain has been used for the staining of blood parasites.The fixation of blood smears in methyl alcohol or the use of the May-Grunwald staining solution is followed by the use of Giemsa stain for 25 to 30 min. Fix air-dried film in absolute methanol by dipping the film briefly (two dips) in a Coplin jar containing absolute methanol. CQN-Ep
