System and methods for processing analyte sensor data for sensor calibration
First Claim
1. A method for analyzing data from an analyte sensor, the method comprising:
- substantially simultaneously receiving data from a first substantially continuous analyte sensor implanted in a host and a second substantially continuous analyte sensor implanted in the same host at the same time, wherein the first and second sensors are designed differently, whereby the first and second sensors exhibit different stabilities;
processing in real-time, by a processor module, the data from the first and second sensors to diagnose a deficiency in the data from the first or second sensor and/or calibrate the data from the first or second sensor; and
outputting glucose values in response to the processing.

Abstract
Systems and methods for processing sensor analyte data are disclosed, including initiating calibration, updating calibration, evaluating clinical acceptability of reference and sensor analyte data, and evaluating the quality of sensor calibration. The sensor can be calibrated using a calibration set of one or more matched sensor and reference analyte data pairs. Reference data resulting from benchtop testing an analyte sensor prior to its insertion can be used to provide initial calibration of the sensor data. Reference data from a short term continuous analyte sensor implanted in a user can be used to initially calibrate or update sensor data from a long term continuous analyte sensor.
