Claim Text:
1. A method for determining a glucose concentration measurable with a system having a test strip and a meter, the method comprising: applying a first test voltage between a reference electrode and a second working electrode coated with a reagent layer and applying a second test voltage between a reference electrode and a first working electrode coated with a reagent layer; measuring a first test current, a second test current, a third test current and a fourth test current at the second working electrode in which blood containing glucose is applied to the test strip to cause a transformation of the glucose in the blood from one form of glucose into another form of glucose and generate a current by an electrochemical re-oxidation of a reduced mediator applied to the test strip; measuring a fifth test current at the first working electrode; determining the glucose concentration from the first, second, third, fourth and fifth test currents with an equation of the form: where: G comprises the glucose concentration; I I I I I a, b, c, d, e, f, g, h, k, p, q and s each comprises empirically derived constants; intercept comprises an intercept value determined from a linear regression of a plot of  versus a reference glucose concentration; and slope comprises a slope value determined from a linear regression of a plot of  versus the reference glucose concentration.
