System and methods for processing analyte sensor data
First Claim
1. A method for calibrating data from a glucose sensor, the method comprising:
- receiving sensor data from a glucose sensor, including one or more sensor data points; and
determining, using an electronic system, a stability of the glucose sensor by comparing the sensor data with a waveform template, wherein an amount of agreement between the template and the sensor data is indicative of a level of sensor stability.

Abstract
Systems and methods for processing sensor analyte data, including initiating calibration, updating calibration, evaluating clinical acceptability of reference and sensor analyte data, and evaluating the quality of sensor calibration. During initial calibration, the analyte sensor data is evaluated over a period of time to determine stability of the sensor. The sensor may be calibrated using a calibration set of one or more matched sensor and reference analyte data pairs. The calibration may be updated after evaluating the calibration set for best calibration based on inclusion criteria with newly received reference analyte data. Fail-safe mechanisms are provided based on clinical acceptability of reference and analyte data and quality of sensor calibration. Algorithms provide for optimized prospective and retrospective analysis of estimated blood analyte data from an analyte sensor.
