Automated microscopic cell analysis

This disclosure describes single-use test cartridges, cell analyzer apparatus, and methods for automatically performing microscopic cell analysis tasks, such as counting and analyzing blood cells in biological samples. A small measured quantity of a biological sample, such as whole blood, is placed in a mixing bowl on the disposable test cartridge after being inserted into the cell analyzer. The analayzer also deposits a known amount of diluent/stain in the mixing bowl and mixes it with the blood. The analyzer takes a measured amount of the mixture and dispenses in a sample cup on the cartridge in fluid communication with an imaging chamber. The geometry of the imaging chamber is chosen to maintain the uniformity of the mixture, and to prevent cells from crowding or clumping as it is transferred into the imaging chamber by the analyzer. Images of all of the cellular components within the imaging chamber are counted and analyzed to obtain a complete blood count.
