Abstract
An apparatus is provided which includes a reaction cartridge having a plurality of reaction wells having different reagents disposed thereon, at least one well adapted to receive a sample, a well containing particles adapted to bind to the sample and which have the capability of being separated from cells which are not bound to the separation particles and at least one fluorophore adapted to bind to a specific type of cell in the sample, and a wash area adapted for washing a probe. An image forming device is provided to detect images which indicate whether specific reactions have occurred in each of the reaction wells. The apparatus also includes a mechanism for dispensing and aspirating liquids including a mechanism for detecting liquid levels. The device further includes logic for analyzing the information received from the image detection apparatus and processing the information to generate a visual indication of the results of the assays being performed. A microprocessor is provided to assist in the operation of the device as well as in the image processing.
