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
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; andprocessing the sensor data, using the system electronics, wherein the processing is responsive to whether an aberrancy is determined. 2. The method of claim 1, further comprising at least one of: 1) receiving at least one filtered sensor data point from the glucose sensor, or2) filtering the at least one sensor data point from the glucose sensor to generate the at least one filtered sensor data point. 3.
