Abstract
Methods and devices are provided for use in the determination of the concentration of an analyte in a sample. In the subject methods, a sample is introduced to a reagent test strip, where the sample is either a test fluid or a control fluid, where the control fluid is free of a mediator dissolution slowing component and an oxidizing agent when used with an electrochemical analyte concentration determination assay. The concentration of analyte in the sample is determined and the sample is identified as a control fluid or a test fluid. Also provided are devices for determining the concentration of an analyte in a sample, where the devices have a sample identification element for identifying whether a sample is a control or a test fluid. The subject methods and devices find use in a variety of different applications, particularly in the determination of blood glucose concentrations.

26. A method for determining the concentration of an analyte in a sample, the method comprising:
-
providing a system comprising a reagent test strip having a sample receiving region and an electrochemical meter for detenmining the analyte concentration in a sample introduced to the sample receiving region;
introducing a sample to the sample receiving region, wherein the sample is selected from the group consisting of a control fluid and a test fluid, wherein the control fluid is free of a mediator dissolution slowing component and an oxidizing agent;
measuring a signal produced by the sample with the meter;
comparing the value of the measured signal to a reference value;
based on the comparison, identifying whether the sample is a control fluid or a test fluid, wherein the measured signal produced by the control fluid is less than the reference value and the measured signal produced by the test fluid is greater than the reference value; and
determining the concentration of analyte in the sample. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
