ABSTRACT:
A test for occult blood comprises an indicator that registers a chromatic change in the presence of heme and an oxygen-releasing compound, the indicator being carried on a support; a solid oxygen-releasing compound dispersed in a spreadable base and applicator to sample biological material and apply the biological material sample along with the base material-dispersed compound to the support. A chromatic change on the support indicates the presence of occult blood. An examining glove may carry the support at one location and the base material-dispersed compound at another location while a finger of the examining glove may be used as the applicator.
