Methods and devices for use in analyte concentration determination assays
First Claim
1. A method for determining the concentration of an analyte in a sample, said method comprising:
- a. providing a system comprising;
i) a reagent test strip having a sample receiving region, and ii) a meter for determining analyte concentration in a sample introduced to said sample receiving region, b. introducing a sample to said receiving region, wherein said sample is selected from the group consisting of a control fluid and a test fluid, with the proviso that said control fluid is free of a mediator dissolution slowing component and an oxidizing agent when said analyte concentration is determined using electrochemical methods, and c. determining the concentration of analyte in said sample with said meter, wherein said method further comprises determining whether said sample is a control fluid or a test fluid to obtain sample identification information.

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.

- 15. A meter for determining the concentration of an analyte in a sample, wherein said meter comprises a sample identification element for identifying whether a sample is a test fluid or a control fluid, wherein said sample identification element comprises at least one reference value selected from the group consisting of a reflectance value and a current value and said current value is one that is observed in less than about 1 second from the time said sample is introduced to said meter.
