  • Patent number: 4647541
    Abstract: A test kit for preparing a chemical test pad used in testing for the presence of occult blood in a specimen.

The separate packet or compartment being rupturable by applying hand pressure to the outside of the foil package to mix the peroxygen agent powder on the test pad and the guaiac solution prior to removing the absorbant pad from the foil package. The method relates to performing a medical test by activating a test pad bearing one reagent by applying another reagent thereto while remaining wholly within a protective foil package. According to the method a test pad containing the peroxygen agent is wetted with a solution of guaiac in alcohol prior to removal from the protective foil package and exposure to a specimen of fecal material and water in a test for occult blood.
