1. A method for noninvasive measurement of a target analyte in a tissue, comprising the steps of:

  • collecting an analytical signal from the tissue, said collected signal comprising a tissue measurement;

    extracting at least one spectral feature from the analytical signal indicative of the effect of the target analyte on the probed tissue; and

    either correcting a direct analyte measurement based on said at least one feature;

    orcalculating concentration of said analyte indirectly by application of a calibration model to said at least one feature.
