ELECTROCHEMICAL DATA REJECTION METHODOLOGY

摘要

A method for determining the concentration of an analyte in a sample which comprises: a) performing an electrochemical test comprising: (i) contacting the sample with an electrochemical cell comprising at least two electrodes; and (ii) obtaining at least one group of three or more measurements of an electrochemical parameter from the cell, wherein each measurement in each at least one group is obtained at a different time; b) deriving from said at least one group of three or more measurements a single value that is indicative of the time-dependent behaviour of the measured parameter; c) comparing the single value indicative of the time-dependent behaviour of the measured parameter with a pre-determined range of acceptable time-dependent behaviours; d) determining whether the test is acceptable based on the result of said comparison; e) optionally repeating the above-mentioned steps; and f) determining the concentration of the analyte from the measurements obtained from the acceptable test or acceptable tests. Also provided is a device on which such a method can be performed and a computer program suitable for performing the data rejection methodology comprised in the method.
