1. A method for determining the concentration of an analyte in a specimen, the method comprising:

  • generating analytical radiation characterized by a spectral line width less than about 20 nm;

    irradiating the specimen with the analytical radiation while scanning a wavelength of the analytical radiation over an analytical spectral range of at least about 350 nm, wherein the analytical spectral range lies between about 900 nm and about 2700 nm;

    detecting attenuation of the analytical radiation by the specimen over the analytical spectral range;

    providing an indication of the attenuation of the analytical radiation as a function of wavelength;

    correlating the attenuation with predetermined characteristics of the analyte to determine the concentration of the analyte in the specimen; and

    generating an output signal indicative of the concentration.
