Claim:
1. A method of determining blood glucose concentration with a glucose measurement system that includes a test strip and test meter, the test meter having a microcontroller configured to apply a plurality of test voltages comprising first, second and third test voltages to the test strip and measure a current transient output resulting from an electrochemical reaction in a test chamber of the test strip, the method comprising: inserting the test strip into a strip port connector of the test meter to connect at least two electrodes of the test strip to a strip measurement circuit; initiating a test sequence after deposition of a sample by causing the first test voltage to be applied, the first test voltage causing a transformation of analytes in the sample from one form to a different form; switching a first test voltage to a second test voltage different than the first test voltage; changing the second test voltage to a third test voltage different from the second voltage; measuring a second current output of the current transient from the electrodes after the changing from the second test voltage to the third test voltage; estimating a current that approximates a steady state current output of the current transient after the third test voltage is maintained at the electrodes; calculating a blood glucose concentration based on the first, second and third current output of the current transient with an equation of the form: correcting the blood glucose concentration with an equation of the form:
