1. A method for measuring a temperature during a test for determining a concentration of a medically significant component of a biological fluid, comprising the steps of:
- a) providing a sensor in which the biological fluid reacts with a reagent to define a reaction zone; and
b) making a temperature measurement within the reaction zone.

Abstract
A method of measuring an analyte in a biological fluid comprises applying an excitation signal having a DC component and an AC component. The AC and DC responses are measured; a corrected DC response is determined using the AC response; and a concentration of the analyte is determined based upon the corrected DC response. Other methods and devices are disclosed.

8. A method for measuring a temperature during a test for determining a concentration of a medically significant component of a biological fluid, comprising the steps of:
-
a) applying a first signal having an AC component to the biological fluid;
b) measuring a first AC response to the first signal; and
c) using the first AC response to produce an indication of a temperature of the biological fluid. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method of accounting for the effect of a temperature variation on a test for a glucose concentration of a biological fluid comprising:
-
a) applying at least a first test signal having an AC component to the biological fluid, the first test signal having a first frequency;
b) measuring at least a first AC response to the first test signal;
c) determining a temperature value of the biological fluid using the first AC response; and
d) determining a temperature-corrected glucose concentration of the biological fluid based at least in part upon the temperature value. - View Dependent Claims (23, 24, 25, 26)
