A microscope slide for cytological analysis of the type where it is extremely important that the presence of a small number of cancer cells present in a smear be detected. A plurality of spaced parallel lines are permanently placed on the slide with the space between each successive pair of lines defining a reference plane. The spacing between each pair of lines corresponds to the field of view produced by the particular microscope lens and eyepiece being utilized so that when a viewer makes a viewing pass across each successive reference plane that the smear is located in, by keeping the lines continuously in the field of view during each pass, the entire area of the smear will be viewed.
