Abstract

A system is provided for monitoring glucose in a host, including a continuous glucose sensor that produces a data stream indicative of a host'"'"'s glucose concentration and an integrated receiver that receives the data stream from the continuous glucose sensor and calibrates the data stream using a single point glucose monitor that is integral with the integrated receiver. The integrated receiver obtains a glucose value from the single point glucose monitor, calibrates the sensor data stream received from the continuous glucose sensor, and displays one or both of the single point glucose measurement values and the calibrated continuous glucose sensor values on the user interface.

Claims

1. An analyte monitoring system, the system comprising:

an analyte sensor;

a processor coupled to the sensor to determine the concentration of analyte; and

a user interface to provide analyte information to a user;

wherein the system is configured to process data from the analyte sensor responsive to an evaluation of information associated with calibration of the analyte sensor.

2. A method of calibrating an analyte monitoring system, the method comprising:

receiving sensor data from an analyte sensor;

processing data from the analyte sensor responsive to an evaluation of information associated with calibration of the analyte sensor; and

providing analyte information after calibration of the analyte sensor.
