Abstract: A method for compensating an analyte measurement in the event of a low sample volume of a deposited fluid sample onto a test strip having first and second working electrodes and a reference electrode. At least one test voltage is applied between the first and second working electrodes and the reference electrode and current is measured at each of the working electrodes at a predetermined time point. The difference in measured current is compared to a stored threshold. If the difference in measured currents is within the stored threshold, the current measurements are used in determining an analyte of interest at a final test time. If the difference in measured currents is not within the stored threshold, then only the measured current of the first working electrode with a suitable correction applied is used in determining the analyte of interest at the final test time.

Abstract: A method for determining a concentration of an analyte in a fluidic sample is described. A sample is applied to a biosensor including an electrochemical cell having electrodes. A predetermined voltage waveform is applied during at least first and second time intervals. At least first and second current values are measured during the first and second time intervals, respectively. A turning point time is determined during the first time interval at which the measured first current values transition from a first to a second profile. The concentration of analyte in the sample is calculated based on determined turning point time and at least one measured current value. In another example, a physical characteristic of the sample is estimated based on measured current values. The concentration is calculated using a first or second model if the estimated physical characteristic of the sample is in a first or second range, respectively.

Abstract: A method for determining contamination of a biosensor in which the biosensor is loaded into a test meter and a sample is then applied. First and second predetermined test voltages are applied between spaced electrodes of the biosensor for respective first and second predetermined time intervals. First and second current values are measured during the respective first and second predetermined time intervals. Reference values are determined based on the measured first and second current values. Based on one or more of the reference values, a determination of contamination is made. Reporting of the analyte concentration of the sample can be suppressed based on the determination.
