1. An improved method for measuring the sugar content of a fluid in the presence of interfering foreign substances by means of an electrocatalytic sugar sensor which includes a test electrode having a membrane arranged in front of it, said method including the steps of applying potentiostatically to said electrode a reactivation potential and a test potential and measuring and evaluating a current flowing during a test period with a set time delay to determine sugar content said improvement including the step of:

  • applying a reduction potential for a period of time shorter than said test period to said test electrode to reduce the effect of said interfering foreign substances, said reduction potential being more negative than said test potential and being applied after the application of said reactivation potential and prior to the application of said test potential.
