| description | Improved test compositions, devices and methods are provided for detecting peroxidatively active substances in body fluids, body excreta and the like. The test compositions include an indicator or chromogen capable of being oxidized in the presence of a peroxidatively active substance to provide a color change, an oxidizing agent effective to oxidize said indicator or chromogen, and as a potentiating agent capable of enhancing the color obtained, a compound of the formula: (1) wherein R1 is hydrogen, a lower alkyl group of 1 to 4 carbon atoms or hydroxy, and R2, R3 and R4 are independently selected from hydrogen or a lower alkyl group of 1 to 4 carbon atoms; provided that at most only one R group is substituted. |
