Giemsa stain also is used to stain Histoplasma capsulatum, Pneumocystis jiroveci, Klebsiella granulomatis, Talaromyces marneffei (formerly called Penicillium marneffei), and occasionally bacterial capsules. The Giemsa stain is a differential stain that includes a combination of eosin dye, methylene blue, and azure in its composition. A translocation or rearrangement can be detected by this method.

By following simple rules, laboratories can prepare a stock solution of Giemsa stain using Giemsa stain powder, thus ensuring the use of consistent, high-quality stain. Dysmyelopoiesis was classified on the basis of the modified FAB classification systems. 1.
