The enumeration of cells in fluids by flow cytometry is widely used across many disciplines such as assessment of leukocyte subsets in different bodily fluids or of bacterial contamination in environmental samples, food products and bodily fluids. For many applications the cost, size and complexity of the instruments prevents wider use, for example, CD4 analysis in HIV monitoring in resource-poor countries. The novel device, methods and system disclosed herein largely overcome these limitations. The system includes a simple system for CD4 and CD8 counting in point-of-care HIV staging within resource poor countries. Unlike previous approaches, no sample preparation is required with the sample added directly to a chip containing dried reagents by capillary flow. A large area image cytometer consisting of an LED module is used to excite the fluorochromes PerCP and APC labeled targets and a monochrome CCD camera with a combination of two macro lenses captures images of 40 mm² of blood (approximately 1 microliter). CD4 and CD8-T-lymphocyte counts correlate well with those obtained by flow cytometry. The cytometer system described in the present invention provides an affordable and easy-to-use technique for use in remote locations.
