1. A method for measuring or monitoring blood glucose level in a subject, the method comprising:

  • injecting an electrical current into a body tissue of the subject using a first pair of injection electrodes;

    detecting a voltage caused by the current flowing through the body tissue using a second pair of sensing electrodes;

    measuring the impedance of the body tissue using a device for measuring impedance operatively connected to the pair of sensing electrodes; and

    ,calculating the blood glucose level in the subject as a function of the measured impedance including correlating the measured impedance with a predetermined relationship between impedance and glucose levels.
