Abstract
An improved multilayer element for detecting glucose in samples of biological fluid which may contain with fluoride ion as a contaminant or preservative is described. The improved element comprises a buffered Trinder's reagent, which reagent comprises glucose oxidase, peroxidase, 4-aminoantipyrine and a phenolic or naphtholic coupler, which is buffered to a pH between about 4.5 and about 6.0. Such a buffering reduces any interference which may be due to fluoride ion present in the sample under analysis.
