Field stain is a histological method for staining of blood smears. It is used for staining thick blood films in order to discover malarial parasites. Field's stain is a version of a Romanowsky stain, used for rapid processing of the specimens.[1]

Field's stain uses methylene blue and Azure 1 dissolved in phosphate buffer solution, and Eosin Y in buffer solution. Field stain is named after physician John William Field, who developed it in 1941.[2]
