ABSTRACT:
The device is used in the same way as toilet tissue to obtain a stool sample for occult blood testing on a receptor sheet included in the device. The receptor sheet is preimpregnated with guaiac or other suitable reagent. A performance/control monitor is included in the device and is kept separated and spaced apart from the receptor sheet until after the stool sample is obtained. Once the stool sample is obtained, the performance/control monitor is brought into and retained in face-to-face contact with the receptor sheet. Upon return to the physician, the developer reagent is applied to the receptor sheet in the area of the stool and in the area of the monitor. Maintaining the monitor out of contact with the receptor sheet until the stool sample is taken prevents the occurrence of a false positive monitor reaction, which can happen when there is extended contact between the monitor and the reagent impregnated receptor sheet.
