Claim:
1. A method of determining an analyte concentration in a sample, the method comprising: detecting a sample including an analyte introduced to an electrochemical sensor, the electrochemical sensor comprising two electrodes in a spaced apart configuration; reacting the analyte to cause a physical transformation of the analyte between the two electrodes; measuring current outputs at discrete intervals to derive a fill time of the sample in the sensor and a capacitance of the electrochemical sensor with the sample; determining a first analyte concentration value from the current outputs; calculating a second analyte concentration value from the current outputs and the first analyte concentration value; correcting the second analyte concentration value for temperature effects to provide for a third analyte concentration value; correcting the third analyte concentration value as a function of the fill time of the sensor to provide for a fourth analyte concentration value; and correcting the fourth analyte concentration value as a function of the capacitance to provide for a final analyte concentration value in which the current outputs measured at discrete intervals comprise a first current summation i where i(t) comprises the absolute value of the current measured at time t.
