Abstract: A microchannel chip for counting floating microparticles with an optical method is provided. The depth of the microchannel chip is made to be a depth of field such that a clear and sharp optical image of microparticles can be obtained, without necessarily diluting the microparticle mixture inside the microchannel. Consequently, a microparticle counting instrument can easily count microparticles shown on an optical image of the microchannel. Particularly, it enables to count more easily the number of CD3 cells CD4 cells or CD8 cells in white blood cells being stained, without lysing or diluting red blood cells. Therefore, the microchannel chip can advantageously used for counting the number of CD3 cells, CD4 cells or CD8 cells in blood of an AIDS patient to monitor the progression of AIDS.

Abstract: A device for counting micro particles is presented. The device comprises a light source; a chip containing micro particles; an object lens; a CCD camera; a counting part; and a shifter for shifting the position of the chip. It is easy to count the number of micro particles, such as red blood cells or somatic cells, by using the device. The shifter shifts the position of the chip by a predetermined distance at every predetermined time interval in order that a certain area adjacent to the area photographed just before is shifted to the point where the light is incident. Therefore, sub-areas on the chip are photographed successively. The counting part counts the number of micro particles in each sub-area, and adds them together to calculate the total number of micro particles in the samples.
