Method for semi-quantitative determination of glucose in an aqueous testproeve, the test means and test device for use in the determination of the material as well as the use

摘要

The invention provides a nonenzymatic method useful for the semiquantitative determination of glucose, a test composition and test device. Glucose concentration in an aqueous test sample can be determined by preparing a test solution by contacting an aqueous test sample and a dihydroxide component, at an initial pH above 6.5, capable of forming a complex with glucose which complex formation releases a proton, and determining the final pH of the test solution. The invention also provides a self-indicating device format which allows the determination of glucose concentration by merely counting the number of pads which have changed color. No comparison to a color chart is required. The glucose test of the present invention is free of the interferences found in enzymatic glucose tests.
