ABSTRACT:
A device 10 detects the presence of occult blood in feces by employing a sheet 12 of brittle material in which are formed a plurality of chambers 18 holding a liquid reagent solution juxtaposed to an absorbant material 14 impregnated with a guaiac material. The individual chambers 18 provide individual liquid tight enclosures that have thin walls that rupture to release the reagent solution when the device 10 is used to wipe feces from the rectum. The reagent solution reacts with the guaiac material to produce a blue color in the presence of occult blood in the feces.
