Abstract
A solid phase capable of detecting the presence of nicotine and/or nicotine metabolites is described. The solid phase is impregnated with assay reagents including a color determinant, a buffer, a cyanogen releasing agent and a cyanogen halide forming agent. The solid phase provides a means whereby unprocessed urine samples over a wide range of different pH values can be tested for the presence of nicotine and/or nicotine metabolites. The assay results may be determined by direct visualization of the color of the solid phase. Also described are methods of preparing and using the solid phase, and kits containing the solid phase.
