Patent ID: 11231428

Abstract:
A kit and method are used to detect the presence of occult blood in feces. The kit has a closed and sealed package containing a sheet of absorbent material impregnated with a guaiac material and a friable packet holding a hydrogen peroxide solution. The packet is sealed to prevent the solution from escaping the packet until it is manually fracture. With the sheet and the packet both within the closed package and in contact with each other, a user manually compresses the packet to break the packet and release the solution, which is absorbed by the sheet material. The package remains closed for a sufficient time for the solution to be absorbed by the sheet. The user then opens the packaging and removes the sheet that is now wetted with the solution, using the sheet in the conventional manner to collect a feces sample. A blue color appearing on the sheet indicates the presence of occult blood in the feces sample.
