METHODS AND ALGORITHMS FOR CELL ENUMERATION IN A LOW-COST CYTOMETER

摘要

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 device, methods and algorithms (Fig. 1) disclosed herein largely overcome these limitations and can be used in remote location. Briefly, this invention includes the techniques for labeling the fluorescent cells in biological sample and counting the magnetically selected fluorescent cells in the biological sample.
