- 62 SYSTEMS, DEVICES AND METHODS FOR IMPROVING ACCURACY OF BIOSENSORS USING FILL TIME 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 10 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 15 and devices that take advantage of the fill time to make analyte concentration determinations are also provided. 29/[2/110,a 19027 speci doc,62 Introduce sample into device Apply potential between electrodes Measure current over time Determine fill time (FT) Calculate prepulse time (PPT) Apply potential between electrodes for a time = PPT Determine concentration of analyte in sample |
