Patent ID: 7711493

Claim:
A method of obtaining an analyte value in biological fluid of a user with an analyte sensor having two electrode sets coupled to a microprocessor, the method comprising: contacting the two electrode sets with biological fluid of a user, in which each electrode set includes an iontophoretic electrode and an electrochemical sensor element in contact with the biological fluid and each of the two iontophoretic electrodes function as either a cathode or anode while in contact with the fluid; measuring a total signal from the sensor element associated with the iontophoretic electrodes; extracting a signal from the total signal related to the analyte from the sensor element associated with the iontophoretic electrodes; accepting said measurement value when at least a first conditional data integrity screening indicates a skin conductance reading falls within predetermined acceptable ranges or within predetermined threshold values and at least a second conditional data integrity screening indicates that the signals have an acceptable monotonic trend or the signals comprise one or more non-monotonic events as a percentage of the total signals being less than a threshold percentage; integrating, via the microprocessor, the signal related to the analyte over time to obtain a charge signal as being proportional to a value of the analyte, the charge signal being representative of a measurement value of glucose in the biological fluid of the user; displaying the measurement of the biological fluid of the user for diagnostic purposes; or skipping said measurement value when two or more of said two or more conditional data integrity screenings falls outside of predetermined acceptable ranges or beyond predetermined threshold values.
