Various embodiments for methods and systems that allow for a more accurate analyte concentration with a biosensor by determining at least one physical characteristic of the sample containing the analyte and deriving one of a batch slope, sampling time, or combinations thereof to attain accurate glucose concentration.

Accurate analyte measurements for electrochemical test strip based on sensed physical characteristic(s) 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. In one embodiment, the method may be achieved by applying a first test voltage between a reference electrode and a second working electrode and applying a second test voltage between the reference electrode and a first working electrode; measuring a first test current, a second test current, a third test current and a fourth test current at the second working electrode after a blood sample containing an analyte is applied to the test strip; measuring a fifth test current at the first working electrode; estimating a hematocrit-corrected analyte concentration from the first, second, third, fourth and fifth test currents; and annunciating the hematocrit-corrected analyte concentration.

Analyte measurement method and system

Various embodiments for systems and methods that allow for a more accurate analyte concentration with a biosensor by obtaining two calibration codes, one for batch calibration due to manufacturing variations and the other for time calibration due to measured physical characteristics of the fluid sample.

Accurate analyte measurements for electrochemical test strip based on multiple calibration parameters

Various embodiments for a method that allow for a more accurate analyte concentration with a biosensor by determining at least one physical characteristic, typically hematocrit, of the sample containing the analyte and deriving from this characteristic a parameter relating to the biosensor to attain accurate glucose concentration.

Accurate analyte measurements for electrochemical test strip based on sensed physical characteristic(s) of the sample containing the analyte and derived biosensor parameters

Various embodiments for a method, systems and meters that allow for a more accurate analyte concentration with a biosensor by determining at least one physical characteristic of the sample and compensating for the effects of ambient temperature with a defined relationship between temperature in the environment, the meter or the biosensor.

Temperature compensation for an analyte measurement determined from a specified sampling time derived from a sensed physical characteristic of the sample containing the analyte

Various embodiments that allow for a more accurate analyte concentration by determining at least one physical characteristic, particularly hematocrit, of the blood sample containing the analyte, particularly glucose, and deriving a specific sampling time based on a relationship between the physical characteristic and sampling time so that the analyte concentration can be determined with greater accuracy with the specific sampling time point.

Accurate analyte measurements for electrochemical test strip based on multiple discrete measurements defined by sensed physical characteristic(s) of the sample containing the analyte

Analyte measurement method and system with hematocrit compensation

Various embodiments that allow a more accurate electrochemical test strip measurement by identifying erroneous output signals during a glucose measurement thereby ensuring a much more accurate glucose test system.

Method and system to determine erroneous measurement signals during a test measurement sequence

Various embodiments of a technique to sample output signals at different time intervals from each of the electrodes in a biosensor to obtain respective glucose estimates including one where the output signals of at least one combination of electrodes measured at various time intervals are summed together to provide for a combined glucose estimate.

Method and system to determine hematocrit-insensitive glucose values in a fluid sample

Described are methods and systems to apply a plurality of test voltages to the test strip and measure at least 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 are generally insensitive to other substances in the body fluid sample that could affect the precision and accuracy of the glucose concentration.
