1. A method of processing data from a glucose sensor, the method comprising:
- receiving sensor data from a glucose sensor, the data comprising at least one sensor data point;
intermittently or continuously measuring a signal noise, using system electronics, to determine an aberrancy of the sensor data by comparing the at least one sensor data point with at least one substantially time-corresponding filtered sensor data point, wherein an aberrancy is determined when an amplitude of the signal noise exceeds a threshold; and
processing the sensor data, using the system electronics, wherein the processing is responsive to whether an aberrancy is determined.
