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.

Contamination determination of biosensors used in analyte measurement systems

Various embodiments for a method that allow for a more accurate analyte concentration with a biosensor by determining at least one physical characteristic of the sample and determining whether at least one output transient signal of the biosensor is erroneous by monitoring the biosensor and flagging an error if the signal outputs of the biosensor do not meet certain criteria.

Anomalous signal error trap for an analyte measurement determined from a specified sampling time derived from a sensed physical characteristic of the sample containing the analyte

Described and illustrated herein are systems and exemplary methods of operating an analyte measurement system having a meter and a test strip. The methods and systems describe herein allow for trapping various errors during calculation of the analyte due to variations in the structure and materials making up the test strip and ambient temperatures.

Analyte measurement method and system with error trapping

Described are methods and systems to apply a plurality of test voltages to the test strip and measure a current transient output resulting from an electrochemical reaction in a test chamber of the test strip so that a glucose concentration can be determined that account for hematocrits in both typical subjects and neonates.

System and method for measuring an analyte in a sample and calculating glucose results to account for physical characteristics of the sample

Various embodiments for a method that allow for a more accurate analyte concentration with a biosensor by determining at least one physical characteristic of the sample and determining whether a counter or reference electrode is causing an error by monitoring the working electrodes and flagging an error if the signal outputs of the working electrodes do not meet certain thresholds.

Reference electrode error trap determined from a specified sampling time and a pre-determined sampling time

Described and illustrated herein are systems and exemplary methods of operating a multianalyte measurement system having a meter and a test strip. In one embodiment, the method may be achieved by applying a test voltage between a reference electrode and a first working electrode; measuring a first test current, a second test current and a third test current at the working electrode with the meter after a blood sample containing an analyte is applied to the test strip; estimating a hematocrit-corrected analyte concentration from the first, second and third test currents; and displaying the hematocrit-corrected analyte concentration.
