A method and apparatus for non-invasively measuring the concentration of an analyte, particularly blood analyte in blood. The method utilizes spectrographic techniques in conjunction with equilibrating the concentration of the analyte between the vascular system fluid compartment of the test area and the other tissue fluid compartment. An improved optical interface between a sensor probe and a skin surface or tissue surface of the body containing the blood to be analyzed. Multiple readings during the equilibration period are taken and utilized to show the direction and rate of charge of concentration of the analyte in the blood which is useful in optimizing therapeutic response to the collected data.

[ What is claimed is:] [1.]1. A method for non-invasive spectroscopic measurement of analytes, said method comprising the steps of:providing a means for irradiating tissue with infrared energy;providing an output element, said output element operatively connected to a means for measuring a spectrum;providing a means for increasing the rate of equilibration of analyte concentration between tissue compartments, said tissue compartments including vascular and non-vascular compartments;activating said means for increasing the rate of equilibration of analyte concentration and allowing time for sufficient equilibration of analyte concentration between tissue compartments;irradiating tissue including said compartments with said infrared energy so that there is differential absorption of said infrared energy in said tissue; andcollecting infrared energy exiting said tissue through said output element and quantifying said infrared energy with said means for measuring a spectrum.
