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.
