Abstract
Generally, the present invention relates to a method for non-invasive optical measurements at at physiologic sites that may reduce or minimize the effects of skin chemistries that optically interfere with the desired optical measurement. An embodiment of the invention is directed to a method of making an optically-based, non-invasive optical measurement of a first physiologic parameter of a patient. The method comprises probing the tissue of a first epithelial site with a first probe light propagating from the optical sensor and detecting a first signal light received from the first assay site with the optical sensor. The method also comprises measuring a value of a second parameter of the patient and determining the level of the first physiologic parameter within the tissue of the first assay site based on the detected first signal light and on the measured second parameter of the patient.
