Objective To explore the diagnostic value of microbiological examination in the diagnosis of pulmonary Aspergillus infection. Methods the subjects were 100 patients with pulmonary Aspergillus infection treated in the hospital from April 2020 to April 2022. The histopathological sections were taken as the test standard. The sputum of patients was collected for culture, the alveolar lavage fluid was taken for G test, and the venous blood was collected for GM test. The positive results of pathological examination were compared with different microorganisms, and the microbiological examination for different positive pulmonary Aspergillus was compared. Results in 42 patients with parasitic positive type, the detection rate of GM test was 88.10%, which was significantly higher than that of G test 57.14% and sputum culture 35.71%. In 58 patients with invasive positive type, the detection rate of G test and GM test was higher than that of sputum culture 41.38%, the difference was 63.79% and 81.03%, P < 0.05. Conclusion the results of GM test are more accurate, which can provide a reliable basis for clinical diagnosis and treatment, and improve the quality of prognosis of patients. It is recommended to popularize it.
