Method and apparatus for detection of abnormal traces during electrochemical analyte detection

摘要

To detect the abnormal signal path from the electrochemical measurement that is generated by the electrochemical test strip is only a potential is allowed with respect to the cover of the analysis object discrimination in error. Current path has a form expected to be observed at the time tpeak with a decrease in the current peak current. To detect an abnormal signal path, the time tpeak is determined experimentally, is compared to the expected value t'peak, if the two values ​​is greater than a predetermined threshold value of the difference is provided to the user instead of the error message is the test result. Value of t'peak is moved, which is determined during the measurement potential state following the measurement to measure the current is also determined as a function term.
