摘要
There is disclosed a specimen-collection wipe suitable for use in testing for the presence of occult blood in fecal matter or other bodily substance. The wipe comprises a hand-contact surface for manipulating the wipe and an occult-blood detection-test surface for collecting a specimen and supporting it during treatment with an occult-blood indicator fluid. The material from which the wipe is constructed has a sufficiently low wet strength to permit the wipe to be disposed of in a toilet and preferably has a sufficiently high resistance to seepage to permit the hand-contact surface to remain dry for the duration of the test. The wipe also includes an indicator-activity verification region on which is dispersed a reagent capable of interacting with the occult-blood indicator fluid to provide an indication characteristic of the presence of occult blood.
