1. A method, comprising:
- receiving a plurality of signals from a transcutaneously positioned analyte sensor;
receiving a reference data;
calibrating the analyte sensor based on the received reference data to generate calibrated sensor data;
detecting a change in the level of the received plurality of signals from the analyte sensor exceeding a predetermined threshold level within a preset time period after calibrating the analyte sensor; and
generating an output signal based on the detected change.
