Abstract: Objective To investigate the value of ultrasound-guided pleural biopsy（USPB）combined with pleural effusion test in the diagnosis of tuberculous pleurisy．Methods A total of 96 patients with tuberculous pleurisy（exudative pleurisy）admitted to the Guangzhou Chest Hospital from June 2021 to June 2023 were selected．The accuracy,specificity,and sensitivity of pleural effusion test（including adenosine deaminase and bacterial culture）,USPB,and their combination were calculated and analyzed．Results The diagnostic accuracy of pleural effusion was 73.96% and the sensitivity was 72.84%．The diagnostic accuracy of USPB was 85.42% and the sensitivity was 82.71%．The diagnostic accuracy 88.54% and sensitivity 90.12% of USPB combined with pleural effusion test were significantly higher than that of pleural effusion alone（P<0.05）,but there was no significant difference in the diagnostic specificity of pleural effusion,USPB and combination of them（P>0.05）．Conclusions USPB combined with pleural effusion test has high clinical value in the diagnosis of tuberculous pleurisy．
