General description
The dry mixture of the Leishman′s eosin methylene blue dye for microscopy, is used for the self-preparation of the Leishman′s staining solution. The staining method according to Leishman is one of the standard techniques in hematological diagnostic procedures. Like Wright′s eosin methylene blue and May-Grünwald′s eosin methylene blue, it is used for staining of blood and bone marrow smears and clinical cytological specimens. The dye is chemically quality-certified according to highest standards and strict specifications. As an IVD product and CE registered, it can be used hassle-free in diagnostics and laboratory accreditations. For more details, please see instructions for use (IFU).
