The article presents the author's views about a study which states that the microscopic-observation drug-susceptibility assay was more sensitive than standard tests for diagnosing tuberculosis. Sputum microscopy is the primary method for diagnosing tuberculosis in resource-limited countries where 95% of tuberculosis cases occur, but it can only detect, at best, 50% of the cases. Sputum processing and fluorescence microscopy are more sensitive than conventional direct microscopy.
