Cell Counting

Cell counting is any of various methods used for the counting or similar quantification of cells in the life sciences, including medical diagnosis and treatment. Cell counts within liquid media are usually expressed as a number of cells per unit of volume. Cell counting is an integral part of determining cell concentrations for plating in culture, determining cell viability, assessing the results of cell isolation procedures, determining concentration of pathogens in the body fliud to evaluate the progress of an infectious disease, determining the concentration of various blood cells to assess the health situation of a person and controlling the dose of cells administered to a patient. Cell counting can be performed either by manually using a hemocytometer, or by using an automated cell counter.
