PRECISE ANALYTIC MEASUREMENT FOR AN ELECTROCHEMICAL TEST STRIP BASED ON MEASURED PHYSICAL CHARACTERISTICS OF AN ANALYTIC SAMPLE AND DERIVATIVES OF THE BIOSENSOR

摘要

1. A method for determining the concentration of analyte in a liquid sample using a biosensor having at least two electrodes and a reagent located on at least one of the electrodes, comprising: applying a liquid sample to at least one electrode to start the analyte testing sequence; applying a signal to the sample in order to determine the physical characteristics of the sample; summing up another signal to the sample, leading to the physical transformation of the sample; measuring at least one output signal from the sample; p obtaining an estimated analyte concentration from at least one output signal at one of a plurality of predetermined time points from the start of the test sequence and at least one predefined biosensor parameter; generating a first parametric biosensor coefficient based on the physical characteristic of the sample; calculating the first analyte concentration, based on the first parametric coefficient of the biosensor and at least one output signal, measured at one of a number of predetermined times from the start of the test sequence; generating a second parametric coefficient of the biosensor based on the approximate analyte concentration and physical characteristics of the sample; calculating a second analyte concentration based on the second parametric coefficient of the biosensor and at least one output measured tested at one of the many predefined times from the start of the sequence
