ABSTRACT:
Disclosed is a method wherein osmotic activity of biological cells immersed in a suspension solution is induced by an osmotic or lytic shock and is monitored in an electronic volume sensing particle analyzer of the Coulter Counter.RTM. type, the method including the steps of passing a high frequency current and a low frequency current through an aperture of said particle analyzer to create detectable signals for classifying the cells into populations of unaltered, altered, and ghost cells.
