Claim Text:
1. A method of determining the concentration of an analyte in a sample, comprising: applying a sample to an electrochemical sensor strip, the sensor strip including a first electrode, the first electrode including at least one first layer on a first conductor, the at least one first layer including an enzyme system and at most 8 μg/mm applying a pulse sequence to the sample, the pulse sequence comprising at least 2 duty cycles within 3 to 14 seconds, wherein the at least 2 duty cycles each comprise an excitation, and the excitations are separated by a relaxation, determining current measurements from the sample responsive to the pulse sequence; and determining the concentration of the analyte in the sample from the current measurements, the determined concentration having at least one of a stability bias of less than ±10%, a hematocrit bias of less than ±10% for whole blood samples over a 20 to 60% hematocrit range, and an intercept to slope ratio of at most 20 mg/dL.
