Peak offset correction for analyte test strip

摘要

Measurement with a test strip having two working electrodes (12, 14), using the current transient (402, 404) for each working electrode measured at a predetermined durational offset (Tpred1, Tpred2) from a peak (408, 410) of the current transient.

1. A method of determining analyte concentration in physiological fluid, the method comprising:
providing a reagent disposed between a first electrode and a second electrode; depositing a physiological fluid on the reagent; causing a physical transformation of an analyte in the physiological fluid into a different from and generating a current transient from each of the first and second electrodes; determining a peak in the current transient for each of the first and second electrodes; measuring a value of the current transient at a predetermined temporal offset from the peak of each current transient from each of the first and second electrodes in which the temporal offset for the first electrode comprises a first time offset from the peak of the current transient of the first electrode and the temporal offset from the peak of the current transient of the second electrode comprises a second time offset different from the first time offset; and calculating the analyte concentration from the measured current values of the first and second electrodes in the measuring step.
