<p>A method is provided to ascertain the total number of cells per unit volume of a cell specimen in an apparatus which does not measure the volume of a suspension containing the specimen as it is being analyzed. The method comprising mixing a suspension of a known quantity of particles having a first light scatter signal with a known volume of a cell specimen having a second light scatter signal different from the first signal to obtain a suspension having a concentration of particles per specimen volume, passing each of said particles and each cell in said cell specimen, in turn, through a light beam, each of said particles and cells producing at least one forward light scattering pattern, counting the number of cells and the number of particles in a portion of said suspension, and determining the total number of cells per unit volume of specimen.</p> |
