Field's stain A is a histological method for staining of blood smears.
Field's stain is a version of a Romanowsky stain, used for rapid processing of the specimens. Polychromated methylene blue and eosin stains selectively basophilic and acidophilic cellular elements to demonstrate blood cells and hemo-parasites. This staining method is used for screening thick films of malarial parasites.
