1. A method for determining a glucose concentration with a system having a test strip and a meter having a test circuit including a microprocessor, the method comprising:

  • initiating a chemical reaction between a reference electrode and a second working electrode coated with a reagent layer and between the reference electrode and a first working electrode coated with a reagent layer of the test strip;

    measuring a primary test current and a secondary test current on one of the first and second working electrodes;

    determining whether a difference between the primary test current and secondary test current is less than zero; and

    upon the determining being true, deriving a glucose concentration based on the plurality of test currents else otherwise returning an error.
