SYSTEM AND METHODS FOR PROCESSING ANALYTE SENSOR DATA FOR SENSOR CALIBRATION
First Claim
1. A method for calibrating a continuous analyte sensor, comprising:
- receiving sensor data from a continuous analyte sensor, wherein the sensor data is indicative of a glucose concentration in a host;
determining a conversion function, using a processor module, wherein the conversion function comprises a slope and a baseline, wherein the slope is representative of a sensor sensitivity, and wherein at least one of the slope or the baseline is determined based on prior distribution information; and
converting the sensor data using the conversion function.

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.
