ABSTRACT:
A swab is impregnated with a test reagent such that a test for a specific substance can be effected by rubbing the impregnated swab over the surface to be tested and then viewing the swab for a reagent reaction. The swab may have a hollow stem, and within the hollow stem is a cartridge within another cartridge. An activator solution is in one of the cartridges and a reagent is in another of the cartridges. A method for testing for a substance includes impregnating a swab, and rubbing the swab over a surface suspected of containing the substance. If the substance is present in the surface, a reaction with the substance produces an easily detectable color on the swab tip.
