    Abstract: Apparatus and methods are described for use with a digital microscope unit that includes a digital microscope. A biological cell sample disposed within a sample carrier, is received into the digital microscope unit. For at least one imaging field of the biological cell sample, it is determined that, within the imaging field, there is a variation in the focal depth of the biological sample with respect to the microscope. At least one image of the imaging field is captured. A characteristic of the biological sample is determined by analyzing the captured image of the imaging field, the analyzing including, in response to determining that there is a variation in the focal depth of the biological sample with respect to the microscope, accounting for the variation in the focal depth of the biological sample with respect to the microscope. Other applications are also described.

    Abstract: Apparatus and methods for use with a blood sample are described. The blood sample is stained with Hoechst stain and Acridine Orange stain. A plurality of images of the blood sample are acquired. An object is identified as being a white blood cell candidate. A first stained area, which is stained by the Hoechst stain and which is disposed within the white blood cell candidate, is identified. A second stained area, which is stained by the Acridine Orange stain and which is disposed within the white blood cell candidate, is identified. A white blood cell is detected by determining that structural features of the stained areas satisfy predetermined criteria associated with a white blood cell. Other applications are also described.

    Abstract: Apparatus and methods are described for use with a cell sample. For each of one or more imaging fields of the cell sample, a depth scan of the cell sample is performed using a microscope. One of the depth levels is identified as being an optimum focal plane for imaging one or more entities within the sample using the microscope, at least partially in response to detecting that the depth level corresponds to a drop in image contrast relative to image contrast at other depth levels. Based upon the depth level identified as being the optimum focal plane for each of the one or more imaging fields of the cell sample, a scanning depth interval over which to perform a depth scan of the cell sample at a further imaging field is defined. Other applications are also described.

    Abstract: Provided is a method for imaging a blood sample and a kit and system for executing the method. The method includes introducing a cell suspension including red blood cells onto a base surface of a carrier having a vertical height (H) being greater than or equal to a vertical depth (h) of the cell suspension when on the base carrier, the cell suspension including a cell concentration (C) being determined by a defined function; allowing the cells in the cell suspension to settle on the base surface of the carrier to form a monolayer of cells thereon; and acquiring at least one microscope image of at least a portion of the monolayer of cells; wherein the at least one microscope image is obtained by a microscope set to Depth Of Field that is not more than 20% of the vertical height of the cell suspension settled on the base surface.
