Objective This study aims to assess the clinical value of sputum and bronchoalveolar lavage fluid examination combined with acid-fast bacilli detection to provide a reference for the diagnosis and treatment of pulmonary tuberculosis.Methods We collected and analyzed relevant test data from patients who underwent smear and/or isolation of sputum and bronchoalveolar lavage fluid for acid-fast bacilli or Mycobacterium detection within the same week from January 2021 to July 2021.The test results'similarities and differences were analyzed.Results Of the 272 patients,the positive rates of sputum smear,alveolar lavage fluid smear,sputum isolation,alveolar lavage fluid isolation(hereinafter referred to as"A""B""C"and"D")were 14.71％(40/272),19.49％(53/272),25.00％(67/268)and 31.90％(74/232),respectively.The positive rate of the four tests as parallel tests was 37.50％(102/272).The result modes of A+C+,A-C+,A+C-,A-C-and A-CN(the"+""-"and"N"in the super-script stood for"positive""negative"and"undetected")accounted for 14.71％(40/272),13.97％(38/272),0,69.85％(190/272),1.47％(4/272)respectively,and the result modes of B+D+,B-D+,B+D-,B-D-and B-DN accounted for 19.12％(52/272),8.82％(24/272),0.37％(1/272),56.99％(155/272),14.71％(40/272).The percentages of these re-sult modes of A+B+,A+B-,A-B+and A-B-were 14.71％(40/272),0,4.78％(13/272),80.51％(219/272),respec-tively.The percentages of these result modes of A+D+,A+D-,A+DN,A-D+,A-D-,A-DN,AND+,AND-and ANDN were 19.12％(52/272),5.51％(15/272),4.04(11/272),8.09％(22/272),51.74％(140/272),10.29％(28/272),0.74％(2/272),0.37％(1/272),and 0.37％(1/272),respectively.Conclusion Compared with more common sputum tes-ting,for acid-fast bacteria,performing bronchoalveolar lavage fluid testing for acid-fast bacteria in alveolar lavage fluid can signifi-cantly improve etiological diagnostic performance for tuberculosis,which is worth promoting extensively in clinical practice.
