Abstract
Methods and devices and systems for determining an analyte value are disclosed.
Claims20
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 the determined sensitivity value to signals associated with the monitored analyte level including the defined data set;
- and
- estimating a time constant associated with an analyte sensor used to monitor the analyte level.
3 more elements
A computer implemented method, comprising:
- calibrating analyte data associated with a monitored analyte level received from an analyte sensor based on a reference measurement;
- determining a lag time constant associated with the calibrated analyte data;
- and
- performing lag correction of the calibrated analyte data based on the determined time lag constant.
