Abstract

Methods for determining a concentration of an analyte in a sample, and the devices and systems used in conjunction with the same, are provided herein. In one exemplary embodiment of a method for determining a concentration of an analyte in a sample, a sample including an analyte is provided in a sample analyzing device having a working and a counter electrode. An electric potential is applied between the electrodes and a measurement of a parameter correlating to changes in a physical property of the sample analyzing device is calculated. A concentration of the analyte in view of the parameter correlating to a change in the physical property can then be determined Systems and devices that take advantage of the parameter correlating to changes in a physical property to make analyte concentration determinations are also provided.

First claim

What is claimed is:

1. A method for determining a concentration of an analyte in a sample, the method comprising:
introducing a sample including an analyte into an electrochemical cell of a sample analyzing device to cause a transformation of the analyte, the electrochemical cell having a first electrode and a second electrode;
determining a measurement of a parameter correlating to a physical property of the electrochemical cell, said parameter comprising a measured capacitance…
