This study examined the possibility of using serum fluorescence spectroscopy and machine learning for the rapid and accurate identification of patients with cholecystitis. Significant differences were observed between the fluorescence spectral intensities of the serum of cholecystitis patients (<jats:italic>n<\/jats:italic>\u2009=\u200974) serum and those of healthy subjects (<jats:italic>n<\/jats:italic>\u2009=\u200971) at 455, 480, 485, 515, 625 and 690\u2009nm. The ratios of characteristic fluorescence spectral peak intensities were first calculated, and principal component analysis (PCA)\u2010linear discriminant analysis (LDA) and PCA\u2010support vector machine (SVM) classification models were then constructed using the ratios as variables. Compared with the PCA\u2010LDA model, the PCA\u2010SVM model displayed better diagnostic performance in differentiating cholecystitis patients from healthy subjects, with an overall accuracy of 96.55%. This exploratory study showed that serum fluorescence spectroscopy combined with the PCA\u2010SVM algorithm has significant potential for the development of a rapid cholecystitis screening method.<jats:inline-graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"graphic\/jbio202200354-gra-0001.png\"
