WebWright (Wright-Giemsa) stain Used in hematology, this stain is not optimal for blood parasites. It can be used if rapid results are needed, but should be followed up when possible with a confirmatory Giemsa stain, so that Schüffner’s dots can be demonstrated. Giemsa stain Recommended for detection and identification of blood parasites. WebAbstract Wright-Giemsa staining is a common procedure that is performed routinely in hematology laboratories. Consistency in intra-laboratory staining quality is essential for accurate morphological interpretation of blood smears. csec china

WebWorking Wright-Giemsa solution for rapid staining (Wright-Giemsa to buffer solution ratio 1:3) Working solution must be prepared in 1:3 ratio (for instance, add 30 ml of Wright-Giemsa solution to 60 ml of Buffer solution, pH 6.8 or 7.2 and stir well). Working Wright-Giemsa solution for classic staining (Wright-Giemsa to buffer solution ratio 1:5) WebApplication. When blood films are stained using Wright-Giemsa Stain, the white blood cell nucleus and cytoplasm take on the characteristic blue or pink coloration. The combination of purified eosin and thiazine dyes in the product eliminates inconsistent staining and yields reproducible chromogenic responses. Web• Remember to prepare stocks of Giemsa and buffered water (pH 7.2) early enough that QC proce-dures can be completed in time. • Store the Giemsa stock and buffered water in tightly stoppered, dark bottles in a cool place away from direct sunlight. • Filter the small amount of Giemsa stain that will be used as a working solution and csec child
