ABSTRACT:
A non-invasive method of monitoring a biological parameter concerning a bodily fluid of a subject, e.g., blood glucose of a human subject. The method includes: placing an electrode against a site of the skin of the subject; measuring impedance of the skin and determining the parameter therefrom; and using substantially the same site in another determination. Another non-invasive monitoring method includes: exposing a skin site to an aqueous salt solution for a pre-determined first period of time; removing excess of the solution from the site; measuring impedance at the site; exposing the site to the solution for a pre-determined second period of time and repeating the removing and measuring steps. It is determined whether the impedance measured falls within a pre-determined range. The latter exposure and removal steps are repeated, if necessary, until two consecutive impedance measurements within the pre-determined range are obtained.
