1. A method of determining glucose and ketone values in a sample, the method comprising the steps of:

  • providing a test element configured for electrochemically determining glucose and ketone values in a sample;

    contacting the test element with the sample, wherein the test element includes;

    a first reagent material comprising a first coenzyme-dependent enzyme for determining the ketone value and at least one first reagent material coenzyme selected from the group consisting of thio-NAD, thio-NADP and a compound according to formula (I), wherein the first reagent material is associated with a first electrode system of the test element, anda second reagent material comprising a second coenzyme-dependent enzyme for determining the glucose value and at least one second reagent material coenzyme selected from the group consisting of FAD, NAD, NADP, thio-NAD, thio-NADP and the compound according to formula (I), wherein the second reagent material is associated with a second electrode system of the test element,wherein the compound according to formula (I) is as follows;
