ABSTRACT:
An absorbent collection strip has attached thereto a detection strip impregnated with a reagent to respectively form collection and detection regions of an integral pad. A dermal surface is wiped with the collection region to remove a contaminant of interest therefrom and collect it on the collection region, which is then wetted with a solvent which has a selective affinity for the contaminant. The solvent carries the contaminant or a reaction product thereof by capillary action through the collection region to the detection region where it reacts with the reagent to produce a color change which indicates the presence of the contaminant. The collection region may also be impregnated with a substance for either facilitating removal of the contaminant from the dermal surface or for cooperation with the reagent in producing the color reaction. The solvent may be either inert to the reagent or may cooperate with it in producing the color reaction. The detection region may be impregnated with plural reagents at physically spaced-apart locations, the reagents being combined by operation of the solvent to produce the color reaction.
