Abstract: An in-the-bowl occult blood test is provided with a flushable matrix having a separate testing site which will indicate the presence of residual oxidizing compounds in the toilet.

Abstract: A specimen-collection wipe 2 is suitable for use in testing for the presence of occult blood in fecal matter or other bodily substance. The wipe 2 includes a substrate 4 having a hand-contact surface 11 for manipulating the wipe 2 and an occult-blood detection-test surface 10 for collecting a specimen and supporting it during treatment with an occult-blood indicator fluid. The substrate 4 has a sufficiently low wet strength to permit the wipe 2 to be disposed of in a toilet and preferably has a sufficiently high resistance to seepage to permit the hand-contact surface 11 to remain dry for the duration of the test. The wipe 2 also includes an indicator-activity verification region 14 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.

Abstract: A test for the presence of occult blood in fecal matter or other bodily substance employs an indicator wipe 2. The indicator wipe 2 has an occult-blood detection-test surface 10 for collecting a specimen and includes a peroxidase-activity indicator reagent dispersed on or located proximate to the specimen collection region. The test involves contacting the specimen-collection region to the bodily substance to obtain a specimen, then applying an oxidizing-agent developing fluid to the specimen and observing any color change to determine if the specimen contains occult blood, and finally disposing of the indicator wipe by placing it in a toilet bowl and flushing it away.
