Abstract
An assay kit comprising an analyte test strip and a color comparator including a plurality of different color fields arranged in an ordered, preferably linear, succession. There is an aperture through each color field so positioned that the reaction zone of the test strip can be placed behind each color field and the color of the reaction zone thereafter viewed through each aperture, with the particular color field framing at least a portion of the reaction zone. The color comparator can be in the form of overlapping panels of a folder or a label on a bottle. There may be a chart of numerical assay values of the color fields such that the edge of the testing strip underlies the numerical value of the color field being viewed, or the testing strip may have a window therein which frames the numerical value of the color field being viewed. This invention has application in test kits for biological substances, (i.e. glucose, cholesterol) and drugs of abuse; and, in test kits for environmental toxins.
