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, the method includes detecting a presence of a sample in an electrochemical sensor including two electrodes. A fill time of the sample is determined with the two electrodes and a correction factor is calculated in view of at least the fill time. The method also includes reacting an analyte that causes a physical transformation of the analyte between the two electrodes. A concentration of the analyte can then be determined in view of the correction factor with the same two electrodes. Systems and devices that take advantage of the fill time to make analyte concentration determinations are also provided.
