Abstract
A method is disclosed for accurately providing general calibration of near-infrared quantitative analysis instruments for almost any individual user. The general calibration method comprises comparing an individual's near-infrared spectrum to a plurality of near-infrared spectral clusters. Each near-infrared spectral cluster has a set of calibration constants associated therewith. The calibration constants of the spectral cluster most closely associated with the individual spectra are used to custom calibrate the near-infrared analysis measurement instrument.
Claims4
A method for calibrating a near-infrared analysis instrument for the measurement of a blood analyte, said method comprising:
- (a) obtaining a near-infrared optical absorption measurement through a body part of an individual;
- (b) comparing said optical absorption measurement with each spectral cluster of a plurality of spectral clusters, each of said spectral clusters having a set of calibration constants associated therewith;
- (c) identifying which of said plurality of spectral clusters corresponds to said optical absorption measurement;
- and
- (d) applying the set of calibration constants associated with the identified spectral cluster to said near-infrared optical absorption measurements to obtain a measurement of said blood analyte.
