Giemsa stain
The related stains are known as the buffered Wright stain, the Wright-Giemsa stain (a combination of Wright and Giemsa stains), and the buffered Wright-Giemsa stain, and specific instructions depend on the solutions being used, which may include eosin Y, azure B, and methylene blue (some commercial preparations combine solutions to simplify staining). The May–Grünwald stain, which produces a more intense coloration, also takes a longer time to perform.
