Claim Text:
1. A method for determining an analyte in a sample in which the sample is applied to an electrochemical test strip and evaluated using an analyte detection apparatus, wherein the sample may be a sample for evaluation or a control solution, wherein the analyte detection apparatus performs the steps of discriminating between a sample for evaluation and a control solution by the steps of: (a) applying a potential difference between first and second electrodes in the test strip for a period of time sufficient to establish a chemical potential gradient between the electrodes; (b) thereafter switching off the applied potential whereby the chemical potential gradient begins to decay; (c) determining the rate of decay of the chemical potential gradient in the absence of applied potential, and (d) comparing the determined rate of decay of the chemical potential gradient to pre-determined reference value, wherein the comparison indicates whether the applied sample is a sample for evaluation or a control solution.
