Abstract:
A system comprising a plurality of colorimetric alcohol concentration tests for analyzing a sample for the presence of ethanol, said system comprising:a) a delivery system configured to dispense said plurality of colorimetric alcohol concentration tests individually, wherein said delivery system comprises a protective packaging housing said colorimetric alcohol concentration tests, said packaging comprising a heat-sealed plastic inner layer, a foil or polymer intermediate barrier layer, and a paper, cardboard, or polymer outer layer; b) a plurality of colorimetric alcohol concentration tests contained in said packaging of said delivery system, wherein said colorimetric alcohol concentration tests comprise an alcohol oxidase enzyme and a desiccant, wherein said colorimetric alcohol concentration tests produce substantially no detectable color signal unless said sample contains an alcohol concentration corresponding to a blood concentration of 0.04% and wherein said colorimetric alcohol concentration tests produce a detectable color signal when said sample contains an alcohol concentration corresponding to a blood concentration above 0.04%, wherein said colorimetric alcohol concentration tests are stable in said delivery system for at least one year.
