Abstract
An apparatus for, and a method of, characterizing a plurality of particles carried by a fluid that can be urged to move through a channel in a microfluidic cassette by combining data analysis of a first signal that is optically-based, and data analysis of a second signal that is electrically-based. Optically-based information is typically obtained by a digital image sensor. Electrically-based information can be obtained by direct measurement of impedance; sometimes in an arrangement operating under the Coulter principle. Data provided by exemplary characterization includes at least one of: volumetric cell count; viability percentage or ratio; particle type; and a particle size histogram.
