Abstract
A disease diagnostic method and apparatus in which a two-dimensional pattern diagram representing the relation between integrated values of peaks and the retention times in a chromatogram of substances in a body fluid of a subject is obtained to be geographically compared, for disease diagnostic purpose, with a two-dimensional pattern diagram representing the relation between integrated values of peaks and the retention times in a chromatogram obtained through separating and detecting substances in a body fluid of a normal person, and also with two-dimensional pattern diagrams representing the relation between integrated values of peaks and the retention times in chromatograms obtained through separating and detecting substances in a body fluid of abnormal patients classified by diseases.
