ABSTRACT:
The device consists of a base sheet of impermeable plastic such as vinyl, or the like, and a guaiac stool receptor sheet adhesively secured thereto. The base sheet is sufficiently larger than the receptor sheet so to form an impermeable skirt which surrounds the receptor sheet so as to form an hermetic barrier protecting the receptor sheet on the underneath one of two of the devices when stacked one on top of the other. A performance/control monitor is included on the device. The monitor includes a peroxidatively active material such as hematin, or the like, which confirms the reactively of the guaiac-impregnated sheet, as well as the activity of the peroxide developing solution. The monitor material is kept out of reactive contact with the guaiac receptor sheet until the developer reagent is applied to the device. A stack of the devices is packed in a sealed container of plastic, or the like, so that the individual devices can be removed from the container one at a time. The devices are designed for use in the physician's office for reception of stool smears taken manually on a rubber glove or finger cot by the physician from patients.
