Patient data, including sex, age, and laboratory test results, were collected. Through sparse partial least squares discriminant analysis, the most informative features were extracted from the dataset. Six classic machine learning algorithms were utilized to develop the optimal predictive model through 1000 bootstrap resamplings. Finally, the model was validated on an independent clinical validation dataset.  \nResults: The training dataset comprised 485 febrile patients (141 with T. marneffei infection) . The clinical validation dataset comprised 1,953 febrile patients (13 with T. marneffei infection) . The random forest model demonstrated the highest performance in classifying T. marneffei-infected patients, with an area under the receiver operating characteristic curve of 0.987 in out-ofbag validation and 0.989 in clinical validation. The model also exhibited good specificity (0 .999) for T. marneffei infection and good sensitivity (0 . 845) in predicting bacteraemia in clinical validation.  \nConclusion: A random forest model can effectively utilize routine clinical laboratory data to predict T. marneffei infection and bact","cbCaifrpPltMVmei","https://ap.wps.com/l/cbCaifrpPltMVmei","pdf",1958336,5,1,12,"English","en",105,"#
