METHOD AND DEVICE FOR DIAGNOSING CHRONIC FATIGUE SYNDROME (CFS) BY USING NEAR INFRARED SPECTRUM

摘要

The present invention provides a method and device of quantitatively or qualitatively examining and diagnosing chronic fatigue syndrome (CFS) by: irradiating a sample derived from an examinee or other animal with light having a wavelength in a range of 400 nm to 2500 nm or a wavelength in part of the range; detecting reflected light, transmitted light, or transmitted and reflected light to obtain an absorption spectral data; and analyzing absorbance at all measurement wavelengths or at specific wavelengths in the absorption spectral data by using an analytical model prepared beforehand.
