Abstract
Methods and devices for automatically distinguishing between a control solution and an actual patient/user sample in a biosensor are provided. The solution is introduced into an electrochemical cell having a working and counter electrode. Electric pulses are applied to the cell and resultant signals are measured. Based on a comparison of the measured signals, a meter can determine whether the sample is a control solution or an actual patient/user sample.

35. A system for automatically distinguishing between a control solution having a known, predetermined concentration of an analyte and an actual patient/user sample in a biosensor comprising:
-
a sample reception region; a reaction reagent system in said sample reception region comprising; an oxidation-reduction enzyme specific for the analyte; a first electron mediator capable of being reversibly reduced and oxidized; and a second electron mediator, wherein the second electron mediator has a redox potential different from that of the first mediator; and a distinction system configured to identify the control solution. - View Dependent Claims (36, 37, 38, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
