METHODS OF DETECTING HIGH ANTIOXIDANT LEVELS DURING ELECTROCHEMICAL MEASUREMENTS AND FAILSAFING AN ANALYTE CONCENTRATION THEREFROM AS WELL AS DEVICES APPARATUSES AND SYSTEMS INCORPORTING THE SAME

摘要

Methods for measuring analyte concentration in a fluid sample are disclosed. These methods also allow error codes to be provided prior to providing the analyte concentration and allow for correction and / or compensation of interferences such as antioxidants. The measurement methods use information obtained from test sequences having at least one DC block, such as a slow ramped bipolar waveform, and closed circuit conditions are maintained during the DC block. The methods use information about the state of the redox mediator characteristic during electrochemical analysis to provide an antioxidant fail safe if the antioxidant interferes with the analyte concentration. Also disclosed are devices, devices and systems incorporating various measurement methods.
