live cells in a sample, and certain characteristics of cells, such as size, shape,
and the presence of tumor markers on the cell surface. The cells are stained with

other type of light. The measurements are based on how the light-sensitive dye reacts
to the light.; CDISC: A technique for counting, examining or sorting microscopic particles in which
