Devices, systems, and methods are disclosed for determining the number and type of blood cells in a blood sample. The blood sample is collected and held in a slide. In the slide, the blood sample is separated and channeled into at least two sampling chambers, one for red blood cells, another for white blood cells, and optionally yet another for platelets. The sampling chambers have wetting agents, lysing agents, staining agents, or the like therein to mix with the blood and facilitate cell count. The slide is placed in a portable slide analyzer where the sampling chambers are illuminated and images of the sampling chambers are taken. These images are converted into electronic form and sent by a communications module of the slide analyzer to a remote external location where the images are analyzed to determine the number and type of blood cells in the blood sample.
