Disclosed is a novel, 2 component Giemsa stain. The stain comprises a first component which is an aqueous solution of methylene blue, Azure B and a preservative and a second component which is an acetone/dimethyl formamide/water solvent system containing the sodium salt of eosin Y and a buffer. The Giemsa stain effect is obtained by first fixing a blood slide with methanol and then applying the freshly mixed first and second components of the stain. The slide is then rinsed and dried to prepare it for examination.
