摘要
This invention relates to lytic reagents and methods of using the lytic reagents for automatically determining leukocyte subpopulations in blood. More specifically, the new lytic reagents selectively lyse red blood cells and certain leukocyte subpopulations, which enables the differentiation of at least one subpopulation of leukocytes. The lytic reagents contain a polyoxyethylene based surfactant, a quatemary ammonium salt and an acid. When used in combination with a second lytic reagent system, one is able to obtain at least a five part differential of leukocytes by impedance and light scatter measurements, by impedance and radio frequency measurements, or by radio frequency and light scatter measurements.
