1. A method for first day calibration (FDC) of a glucose sensor for measuring the level of glucose in a body of a user, said sensor including physical sensor electronics, a microcontroller, and a working electrode, the method comprising:

  • (a) measuring, by said physical sensor electronics, the electrode current (Isig) for the working electrode;

    (b) calculating, by said microcontroller, a calibration ratio (CR);

    (c) comparing said calibration ratio to a threshold range; and

    (d) based on said comparison, calculating a time interval until the next calibration.
