First Claim
Patent Images
1. A method for detecting whether a disposable, dry reagent, electrochemical test strip is unsuitable for use in determining a concentration of a medically significant component of a biological fluid, comprising:
- a) applying a signal to the tests trip before dosing the test strip, the test strip including a pair of measurement electrodes and a dry reagent, the signal having an AC component, the signal being applied between the measurement electrodes of the test strip;
b) measuring an AC response to the signal; and
c) using the AC response to determine if the test strip is unsuitable for use.

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.
