An improved composition, test device and method for detecting the presence of a sugar in a test sample are disclosed. The composition comprises a sugar oxidase, a peroxidase, a chromogen compound capable of producing a detectable response in the presence of hydrogen peroxide and peroxidase, and an enhancer compound having the structure [Figure] in which the R substituents, same or different, are hydrogen, lower alkyl, lower alkyloxy, aryl or aryloxy; or in which two of the R substituents bound to a common atom together form a closed ring having 3 to about 6 atoms, said ring being saturated, unsaturated or aromatic. R′is hydrogen or an alkyl or alkenyl group having 1 to about 20 carbon atoms. The composition can be incorporated with a carrier matrix to form a test device. The method comprises contacting a test solution with the device and observing any detectable response.
