Abstract
The present invention is related to optical non-invasive methods and instruments to detect the level of analyte concentrations in the tissue of a subject. The spectra of mid-infrared radiation emitted from a subject's body are altered corresponding to the concentration of various compounds within the radiating tissue. In one aspect of the invention, an instrument measures the level of mid-infrared radiation from the subject's body surface, such as the eye, and determines a specific analyte's concentration based on said analyte's distinctive mid-infrared radiation signature.
Claims7
A method of determining an analyte concentration in a tissue of a subject, the subject including an eye with an occular surface and a conjunctiva surface, comprising the steps:
- a. detecting naturally occurring mid-infrared radiation emitted from the conjunctiva without contact with the ocular surface using a non-invasive instrument comprising a mid-infrared detector;
- b. comparing a radiation signature of said mid-infrared radiation to a radiation signature of mid-infrared radiation corresponding to an analyte concentration;
- and
- c. analyzing said radiation signature of said mid-infrared radiation from said subject to determine said analyte concentration in a tissue of said subject.
