ABSTRACT:
Microspores derived from flowering plants are dispersed in fluids to simulate leukocytes. Reconstituted body fluids utilized as standards in clinical examination of fluids such as urine contain a known quantity of microspores to simulate leukocytes when examined under a high power field. Microspores utilized to simulate leukocytes have a particle size of between 10 microns and 25 microns and are stained utilizing the same stains and techniques utilized for staining leukocytes. Microspores derived from the Paper Mulberry tree are highly preferred for use as leukocyte resembling particles.
