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.
