Bronchoalveolar lavage is better than gastric lavage in the diagnosis of pulmonary tuberculosis.

Bronchoalveolar lavage was performed in 62/63 patients with suspected pulmonary tuberculosis and gastric lavage in 60 of the 63. Mycobacteria could be cultured from 14 of the patients. Cultures on bronchoalveolar lavage were positive in 13 of them, while gastric lavage was positive in only 7. Our conclusion is that bronchoalveolar lavage should be performed instead of gastric lavage when pulmonary tuberculosis is suspected.
