The invention is directed to a method and apparatus for detecting and measuring the concentration of an analyte in a tissue and a patient. Particularly, the invention is directed to methods wherein a spectroscopic measurement is combined with an adjunct spectroscopic or non-spectroscopic measurement to provide a more accurate measure of the analyte. The non-spectroscopic measurements include adjunct spectral measurements, adjunct physiological measurements of the patient, the tissue or the patient from whom the tissue was obtained, or adjunct informational determinants. Preferably these methods can be used for determining the level of glucose in a patient and for enhancing a calibration system. |
