System and methods for processing analyte sensor data for sensor calibration
First Claim
1. A system for calibrating a continuous analyte sensor, comprising:
- a continuous analyte sensor configured to provide sensor data indicative of an analyte concentration in a host; and
a processor module configured to determine a conversion function, wherein the conversion function comprises a slope representative of a sensor sensitivity, wherein the slope is determined by selecting a most probable slope from a distribution of slopes, and wherein the processor module is configured to convert 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.
