Abstract

A device and method for selecting and stabilizing proper sites for the measurement of the concentration of an analyte, for example glucose, within the tissue of a subject or patient are disclosed. One embodiment of the device (440) immobilizes the subject's forearm (462) and finger (460), thereby stabilizing measurement sites thereon for exposure to a noninvasive monitor which captures analyte concentration data within the subject's skin. The method involves the choice of a location on the subject's body at which to take the analyte measurement, preferably based on the amount of time that has elapsed since the last time the subject ate.
