A method and test device for determining the glucose concentration in a test sample containing from ½to 5 percent glucose. The method and test device involve incorporating urea-formaldehyde resin in a carrier matrix and subsequently impregnating the carrier with an enzymatic testing composition which includes glucose oxidase, a peroxidatively-active compound and a chromogen. Contact of the carrier with a glucose-containing test sample produces a detectable response whereby the glucose concentration can be determined.
