1. A placement guide used for coupling of an optical probe of an optically based noninvasive glucose analyzer to a sampling site in a sampling skin, said optical probe comprising at least one optical incident member for delivering incident photons into said sampling site and an optical collection member for collecting photons emerging from said sampling site, said guide comprising:

  • a mount having a contact surface at one end, at least a portion of said contact surface being in contact with said sampling skin;

    an aperture, defined by said mount, which is adapted to receive said optical probe, wherein an area defined by said aperture comprises said sampling site; and

    a hydration inducing plug attached, from said aperture, to said mount at said one end, wherein an outer surface of said hydration inducing plug is aligned with said contact surface of said mount, said outer surface being in direct contact with said sampling site;

    wherein said hydration inducing plug acts an optical interface between said optical probe and said sampling site when said optical probe is coupled into said aperture.
