Abstract: Methods, system and devices for providing improved calibration accuracy of continuous glucose monitoring system based on insulin delivery information are provided.

Abstract: Methods, devices, and systems for calibrating an analyte sensor are provided. Embodiments include determining a sensitivity value associated with an analyte sensor, retrieving a prior sensitivity value associated with the analyte sensor, determining whether a variance between the determined sensitivity value and the retrieved prior sensitivity value is within a predetermined sensitivity range, determining a composite sensitivity value based on the determined sensitivity value and the retrieved prior sensitivity value, and assigning a successful calibration sensitivity value based on the retrieved prior sensitivity value when the variance is within the predetermined sensitivity range.

Abstract: Methods and devices to detect analyte in body fluid are provided. Embodiments include processing sampled data from analyte sensor, determining a single, fixed, normal sensitivity value associated with the analyte sensor, estimating a windowed offset value associated with the analyte sensor for each available sampled data cluster, computing a time varying offset based on the estimated windowed offset value, and applying the time varying offset and the determined normal sensitivity value to the processed sampled data to estimate an analyte level for the sensor.

Abstract: Method and apparatus for optimizing analyte sensor calibration including receiving a current blood glucose measurement, retrieving a time information for an upcoming scheduled calibration event for calibrating an analyte sensor, determining temporal proximity between the current blood glucose measurement and the retrieved time information for the upcoming calibration event, initiating a calibration routine to calibrate the analyte sensor when the determined temporal proximity is within a predetermined time period, and overriding the upcoming scheduled calibration event using the current blood glucose measurement are provided.
