Abstract: The present invention is directed to a foldable carton for conveniently displaying the chemical reagents and for conveniently dispensing the chemically impregnated devices for use in performing diagnostic tests and provided in a diagnostic test kit format. The foldable carton of the present invention has two openings. The first opening, the cover panel, has a rack capable of containing thereon, from 1-4 containers of chemical reagents. Because the cover panel is secured to the front of the carton, when the cover panel is fully opened, so as to overlay the front wall of the carton, the chemical reagents contained thereon are forwardly displayed. Preferably, the inside face of the cover panel also contains an instruction panel for refreshing the recollection of those already familiar with the test procedure. The lower end of the front wall is provided with a dispensing flap that opens to permit the sequential withdrawal of a chemically impregnated test device that is slideably stacked within the carton.
