1. A method for evaluating the amount of a visually detectable marker identifying precipitate in a cellular specimen bound to a microscope slide comprising the steps of: obtaining a color digital image of a magnified view of a cellular specimen bound to microscope slide; processing the color digital image to identify a plurality of candidate objects of interest in the cellular specimen; identifying a centroid for identified candidate objects of interest in the plurality of candidate objects of interest; computing a color ratio of at least two color components for each pixel of an area centered about each identified centroid; computing an average color ratio for all pixels in the area centered about each centroid that have a computed color ratio that exceeds a predetermined color ratio threshold; and comparing the computed average color ratio to at least one intensity threshold to evaluate the amount of marker identifying precipitate in each area centered about each centroid.
