A method and apparatus for processing an image of a tissue sample microarray include placing a plurality of tissue samples in an array on a microscope slide. The tissue samples are then simultaneously and uniformly treated, as by staining. Images of the tissue making up the microarray are captured and stored together with identifying information related thereto. The images may be displayed from the digital storage medium using a programmed processor which can select various magnifications for display. The images also can be accessed by network and remotely.
