Claims20
A method for generating analyte measurements of a host, the method comprising:
- generating sensor data during a first time period using a continuous analyte sensor coupled to a sensor electronics unit, the sensor data comprising a plurality of sensor data points;
- accessing, by the sensor electronics unit, calibration information;
- evaluating, by the sensor electronics unit, a predictive accuracy of calibration information;
- determining, by the sensor electronics unit, to request reference data based at least in part on the predictive accuracy of calibration information;
- and
- providing, by the sensor electronics unit, a prompt for reference data.
A continuous analyte sensor system comprising:
