    Abstract: Apparatus and methods are described including analyzing one or more microscopic images of the blood sample using a machine-learning classifier. An entity within the one or more microscopic images is identified using a first classification model, and a first estimated concentration of the entity within the sample is determined, based upon the entity as identified using the first classification model. The entity is identified within the one or more microscopic images using a second classification model, and a second estimated concentration of the entity within the sample is determined, based upon the entity as identified using the second classification model. The first and second estimated concentrations are compared to each other, and, in response to the comparison, a hybrid classification model that is a hybrid of the first and second classification models is used. Other applications are also described.

    Abstract: Apparatus and methods are described for use with a cell sample that includes a plurality of cells disposed in a monolayer. A series of images associated with a series of depth levels of the cell sample are acquired, by performing a depth scan of cell sample with a microscope. One of the depth levels is identified as being an optimum focal plane for imaging one or more entities within the cell sample using the microscope, by identifying that a drop in image contrast occurs at the identified depth level relative to the image contrast of images acquired at depth levels within a given range of distances from the identified depth level. The cell sample is imaged using the microscope, by focusing the microscope at an investigative depth level that is based on the identified depth level. Other applications are also described.

    Abstract: Apparatus and methods are described for use with an output device (34), and a blood sample (12) that was drawn from a subject. A microscope system (10) acquires first and second images of the blood sample at respective times. A computer processor (28) determines whether, between acquisitions of the first and second images, there was relative motion between at least one erythrocyte within the sample and at least one entity within the sample, by comparing the first and second images to one another. At least partially in response thereto, the computer processor determines whether the entity is an extra-erythrocytic or an intra-erythrocytic entity, and generates an output on the output device, at least partially in response thereto. Other applications are also described.

    Abstract: Apparatus and methods are described for use with a blood sample and a display, including acquiring a plurality of images of a microscopic imaging field of the blood sample, each of the images being acquired using respective, different imaging conditions. An artificial color microscopic display image of the microscopic imaging field is generated having a similar appearance to that of a color smear image, by mapping the plurality of images to respective channels of the artificial color microscopic display image. A display is driven to display the artificial color microscopic display image of the microscopic imaging field to a user. Other applications are also described.
