NCT04074369

Brief Summary

This observational Mycobacterium tuberculosis (MTB) diagnostics evaluation study is a prospective study of pulmonary TB suspects who are undergoing sputum or bronchoalveolar lavage fluid (BALF) evaluation for pulmonary TB. The sensitivity and specificity of the CRISPR-based assay will be compared to clinical diagnosis, conventional culture methods and Xpert MTB/RIF assay on same batch specimens.
