Patent ID: 8545693

Claim:
A method for determining a glucose concentration measurable with a system having a test strip and a meter, the method comprising: applying a test voltage between a reference electrode and a working electrode coated with a reagent layer disposed on a matrix layer having a mediator; measuring a first test current, a second test current and a third test current at the working electrode with the meter after a blood sample containing an analyte is applied to the test strip to physically transform the analyte into an enzymatic by-product; determining a glucose concentration from the first, second and third test currents, in which the glucose concentration comprises a value obtained with the following: G = [ ( I 1 I 2 ) p ⁢ I 3 ] - intercept ⁢ ⁢ 1 slope ⁢ ⁢ 1 where: G comprises the glucose concentration; I 1 comprises the first test current; I 2 comprises the second test current; I 3 comprises the third test current; p comprises a power term that depends on of the third test current in which the power term p comprises a value obtained with the following: p = a - b I 3 where a comprises a first tuning parameter between 2.5 and 5 and b comprises a second tuning parameter between 1.75 and 5; intercept 1 comprises an intercept value determined from a linear regression of a plot of [ ( I 1 I 2 ) p ⁢ I 3 ] versus a reference glucose concentration for a batch of test strips; and slope 1 comprises a slope value determined from a linear regression of a plot of [ ( I 1 I 2 ) p ⁢ I 3 ] versus the reference glucose concentration for the particular batch of test strip; and displaying the glucose concentration.
