Patent ID: 8473022

Claim:
A method, comprising: determining a predetermined time period characterized with a rate of change of an analyte level below a preset threshold; defining a data set associated with a monitored analyte level within the predetermined time period; determining a sensitivity value based on the defined data set; applying, using one or more processors, the determined sensitivity value to signals associated with the monitored analyte level including the defined data set; estimating, using the one or more processors, a time constant, associated with an analyte sensor used to monitor the analyte level, using reference data, the monitored analyte level, and the rate of change of the monitored analyte level; performing, using the one or more processors, lag correction of the signals associated with the monitored analyte level based on the estimated time constant; and calibrating, using the one or more processors, the lag corrected signals to estimate a corresponding monitored glucose level.
