Method of detecting bias in enzyme electrode measurements |
摘要 |
A method of determining the concentration of an analyte in a fluid test sample that includes providing an electrochemical sensor adapted to measure the analyte in the test sample. The test sample sufficiently covers a counter and working electrode of the electrochemical sensor. A first potential is applied between the counter and working electrodes for a first predetermined time period and the current is measured and the time is recorded. After the first potential is removed or substantially reduced, a second potential is applied between the counter and working electrodes and the current is measured. The concentration of the analyte is determined in the test sample as a function of the current measured. An index is calculated and compared to at least one predetermined parameter to identify when a bias, if any, exceeds a threshold. An error signal or analyte concentration is displayed depending on the comparison.
