Accurate Analyte Measurements for Electrochemical Test Strip Based on Sensed Physical Characteristic(s) of the Sample Containing the Analyte

摘要

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.

主权项

1. A method of determining an analyte concentration from a fluid sample with a biosensor having at least two electrodes and a reagent disposed on at least one of the electrodes, the method comprising:
depositing a fluid sample on any one of the at least two electrodes to start an analyte test sequence; applying a first signal to the sample to measure or estimate a physical characteristic of the sample; deriving a batch slope for the biosensor based on the measured or estimated physical characteristic; driving a second signal to the sample; measuring an output signal from at least one of the at least two electrodes; and calculating an analyte concentration based on the measured output signal and the derived batch slope from the measured or estimated physical characteristic of the sample.
