Claim of US Patent No. 9,933,385

1. A method of using an electrochemical test sensor, the method comprising the acts of:introducing a fluid sample to the electrochemical test sensor;
applying a pulse sequence to the fluid sample, the pulse sequence comprising at least two duty cycles within 180 seconds, at least one of the duty cycles having a first potential in a first excitation period and a first relaxation period, and after one of the duty cycles, providing a second potential to the sample, the second potential being greater than the first potential, the second potential being supplied after a second relaxation period, the second relaxation period being less than the first relaxation period;
measuring a first current at the first potential responsive to an analyte;
measuring a second current at the second potential responsive to the analyte; and
determining whether the fluid sample is a control solution or an analyte-fluid test sample based on the measured first and second currents.
