发明名称 ACCURATE ANALYTE MEASUREMENTS FOR ELECTROCHEMICAL TEST STRIP TO DETERMINE ANALYTE MEASUREMENT TIME BASED ON MEASURED TEMPERATURE, PHYSICAL CHARACTERISTIC AND ESTIMATED ANALYTE VALUE AND THEIR TEMPERATURE COMPENSATED VALUES
摘要 Various embodiments for a method that allow for a more accurate analyte concentration with a biosensor by determining at least one physical characteristic signal representative of the sample containing the analyte and selecting an analyte measurement sampling time based on measured temperature, physical characteristic and estimated analyte values along with temperature compensations provided for specific parameters used in the test assay.

主权项 1. An analyte measurement system comprising: a test strip including: a substrate;a plurality of electrodes connected to respective electrode connectors; and an analyte meter including: a housing;a test strip port connector configured to connect to the respective electrode connectors of the test strip; anda microprocessor in electrical communication with the test strip port connector to apply electrical signals or sense electrical signals from the plurality of electrodes during a test sequence, wherein the microprocessor may be configured, during the test sequence, to: (a) start an analyte test sequence upon deposition of a sample;(b) apply a signal to the sample to determine a physical characteristic signal representative of the sample;(c) drive another signal to the sample;(d) measure at least one output signal from at least one of the electrodes;(e) measure a temperature of one of the sample, test strip, or meter;(f) determine a temperature compensated value for the physical characteristic signal based on the measured temperature;(g) derive an estimated analyte concentration from the at least one output signal at one of a plurality of predetermined time intervals as referenced from the start of the test sequence;(h) determine a temperature compensated value for the estimated analyte concentration based on the measured temperature;(i) select an analyte measurement sampling time point or time interval with respect to the start of the test sequence based on (1) the temperature compensated value of the physical characteristic signal and (2) the temperature compensated value of the estimated analyte concentration;(j) calculate an analyte concentration (GU) based on a magnitude of the output signals at the selected analyte measurement sampling time point or time interval;(k) apply a temperature compensation to the calculated analyte concentration as a function of the measured temperature and respective alpha and beta parameters (α and β) dependent on the respective calculated analyte concentration and measured temperature to obtain a compensated analyte concentration (GF); and(l) annunciate the compensated analyte concentration(GF).
