Manual platelet count hemocytometer
WebA device used for determining the number of cells per unit volume of a suspension is called a counting chamber. The most widely used type of chamber is called a hemocytometer, since it was originally designed for performing blood cell counts. To prepare the counting chamber the mirror-like polished surface is carefully cleaned with lens paper. Webplatelet count: Definition A platelet count is a diagnostic test that determines the number of platelets in the patient's blood.
