20110152658 | IDENTIFICATION OF ABERRANT MEASUREMENTS OF IN VIVO GLUCOSE CONCENTRATION USING TEMPERATURE - Disclosed herein are methods and systems for generating an estimate of an in vivo analyte concentration and identifying whether the estimate is aberrant. In some embodiments, the system includes a sensor comprising an analyte sensor and a temperature sensing element, and a control unit programmed to identify changes in temperature that may indicate a non-physiologic condition (and result in an aberrant glucose measurement). In some embodiments, the methods include generating an estimate of analyte concentration at a particular time using the analyte sensor, and generating first and second signals indicative of temperature using the temperature sensing element. In some embodiments the methods include identifying the estimate of analyte concentration as aberrant if the magnitude of the difference between the first and second signals indicative of temperature exceeds a threshold value. | 06-23-2011 |
