A correlation of the enumeration of platelets in peripheral smears with platelet counts performed by a direct method is presented. A ratio of 1 platelet per oil-immersion field for every 21,000 platelets of the chamber count indicates the normal average range of platelets to be approximately 7--21 per oil-immersion field.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
