Abstract: Systems and methods are presented for the diagnosis of middle ear pathological conditions based on spectral signatures. Preferred embodiments provide for detection of one or more analytes from the tympanic membrane. Devices use spectral measurements including spectral imaging to non-invasively identify middle ear pathological conditions including cholesteatoma and acute otitis media by providing real-time information of differentially expressed molecules. Devices and methods can also be used to non-invasively detect and quantify blood analytes from the tympanic membrane.

Abstract: Systems and methods of the present invention provide a calibration model that requires minimal information compared with prior techniques. These systems and methods represent the first generalized approach for combined treatment of spectroscopic measurements of a dynamic, mass-transfer system with the underlying kinetic model of said system. The technique can be applied to non-invasive glucose monitoring or monitoring of chemical reaction dynamics.
