Abstract
A method for determining the concentration of sugar in the presence of interfering foreign substances, by means of a test electrode with a membrane placed in front of it, the electrode being contained in an electrocatalytic sugar sensor, whereby the test electrode is set potentiostatically to a reactivation potential and to a test potential and the current flowing during the set test period is evaluated as a test signal. The invention formulates a method such that with varying concentrations of urea a sensitive determination of sugar concentration which is reliable over a long term is achieved. The invention discloses the method which includes the step that after the reactivation potential and prior to the test potential a third potential that is more negative than the test potential is applied to the test electrode. The technique proposed in the invention is particularly appropriate for the determination of the concentration of glucose in body fluids.
