Abstract:
1. A reagentless glucose detection system sized and configured to be portably carried by a patient, comprising: a modulated source capable of emitting a beam of radiation; a detector in an optical path of the beam; a synchronous demodulator in communication with the detector; a housing sized and configured to be portable and used by the patient, and to house the source and the detector; a receptacle formed in said housing for manually receiving a sample element, the receptacle being sized and configured such that at least a portion of the sample element is situated in the optical path when the sample element is situated in the receptacle; and a disposable sample element removably situated in the receptacle of the housing and constructed at least in part from a material through which the radiation can pass, the sample element comprising: further comprising a filtering system in the optical path of the beam, the filtering system configured to transmit the spectral band of radiation; wherein the filtering system is configured to transmit radiation at at least one of the following center wavelengths: about 5.25 μm, about 6.12 μm, about 7.4 μm, about 8.0 μm, about 8.45 μm, about 9.25 μm, about 9.65 μm, about 10.4 μm, about 12.2 μm.
