1. A method for evaluating accuracy of a glucose monitoring sensor, said method comprising:
- receiving blood glucose (BG) values from said monitoring sensor;
evaluating accuracy of said BG values received from said monitoring sensor to obtain a point accuracy using a processor;
receiving BG fluctuations from said monitoring sensor;
evaluating accuracy of direction and rate of said BG fluctuations received from said monitoring sensor to obtain a rate accuracy using said processor;
combining said point accuracy and rate accuracy to obtain an estimate of sensor precision using said processor; and
communicating said estimate of sensor precision to a user using an output device.

Abstract
Continuous Glucose Error-Grid Analysis (CG-EGA) method, system or computer program product designed for evaluation of continuous glucose sensors providing frequent BG readings. The CG-EGA estimates the precision of such sensors/devices in terms of both BG values and temporal characteristics of BG fluctuation. The CG-EPA may account for, among other things, specifics of process characterization (location, speed and direction), and for biological limitations of the observed processes (time lags associated with interstitial sensors).
