Abstract
The present invention provides a method and device of quantitatively or qualitatively examining and judging the presence of virus infection, such as HIV, or the presence of prion infection 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 the absorbance at all measurement wavelengths or at specific wavelengths in the absorption spectral data by using an analytical model prepared beforehand. The analytical model can be prepared by carrying out spectral measurement, with a perturbation being provided, and carrying out a multivariate analysis that brings out perturbation effects.
