The invention shall allow a more accurate electrochemical test strip measurement by identifying erroneous output signals during a glucose measurement, thereby ensuring a much more accurate glucose test system and method. A glucose measurement system comprises a biosensor (62) having electrodes and a meter (10,100). The meter includes a microcontroller (38) configured to drive a signal to the electrodes, measure an output signal during the electrochemical reaction over a series of time intervals, determine an output differential (Delta I) as a difference of the output signal for consecutive time intervals and, if this output differential (Delta I) is greater than a threshold, increment an index value (x) by this output differential (Delta I). When the final index value (x) is greater than or equal to a predetermined index value, then an error is annunciated; otherwise the glucose value is annunciated. |
