SYSTEM AND METHOD FOR COMPENSATING SAMPLE-RELATED MEASUREMENTS BASED ON POLARIZATION EFFECTS OF TEST STRIPS

摘要

A system and a method for correcting an analyte concentration measurement taken by a test strip is described herein. The test strip includes at least two spaced apart electrodes defining an electrochemical cell or reaction chamber. An initial polarization parameter of the test strip is determined at the time of test strip manufacture and a testing polarization parameter is determined at the time of testing. A resulting correction factor is then determined based on the initial and testing polarization parameters. The correction parameter can be applied to a measured analyte concentration in order to correct the measured analyte concentration.

1. A method for determining an analyte concentration of a sample fluid applied to a test strip, the test strip comprising at least two electrodes in spaced relation and defining a reaction chamber, the method comprising:
determining an initial polarization parameter of the test strip at a time of test strip manufacture; determining a testing polarization parameter of the test strip at a time of testing; determining a correction parameter of the test strip based on the initial polarization parameter and the testing polarization parameter; measuring an initial analyte concentration; and applying the correction parameter to the initial analyte concentration to produce a corrected analyte concentration.
