System and methods for processing analyte sensor data
First Claim
1. A system for displaying data from a substantially continuous glucose sensor, the system comprising:
- a sensor data receiving module configured to receive sensor data including one or more sensor data points from the substantially continuous glucose sensor; and
an interface control module configured to display sensor data on a user interface responsive to a level of stability of the sensor data, wherein the level of stability is based at least in part on an evaluation of sensor data to check at least for an indication of a sensitivity change associated with the substantially continuous glucose sensor.

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.
