The test strips employ an alcohol oxidase, Peroxidase and an hydrogen donor indicator such as Tetraalkylbenzidine in a carrier matrix supported on the strip with the alcohol oxidase functioning as a catalyst to convert any ethanol present along with ambient oxygen to acetaldehyde and hydrogen peroxide. The peroxidase function as catalyst to induce a color change in the hydrogen donor and convert the hydrogen peroxide to water.
