Abstract
A testing apparatus for detecting urease in a gastric material taken from a human or lower animal subject is disclosed, the apparatus comprising a dry indicating composition responsive to urease, a backing sheet supporting the dry indicating composition, and a cover sheet sealingly adhered about its periphery to the backing sheet to enclose the dry indicating composition. At least one of the backing sheet or cover sheet has a transparent portion in alignment with the dry indicating composition, and wherein the cover sheet may be peeled from the backing sheet and resealed.
Claims17
A testing apparatus for detecting urease in a gastric material taken from a mammal, said apparatus comprising a dry indicating composition responsive to said urease, said dry indicating composition being absorbed or impregnated into or applied to a backing sheet or absorbed or impregnated into or applied to a wafer carried by a backing sheet, a cover sheet sealingly adhered about its periphery to said backing sheet to enclose said dry indicating composition, at least one of said backing sheet or said cover sheet has a transparent portion in alignment with said dry indicating composition, said apparatus being arranged such that a sample of said gastric material is applied to one side of the indicating composition and an opposite side of said indicating composition is viewed through said transparent region to determine if a color change has occurred, said backing sheet or wafer having a thickness to provide sufficient buffering capacity to neutralize acid present in said gastric material, and wherein said apparatus can be stored at room temperature.
