The diagnosis of active tuberculosis (TB) cases primarily relies on methods that detect Mycobacterium tuberculosis ( Mtb ) bacilli or their DNA in patient samples (e.g., mycobacterial culture and Xpert MTB/RIF assays), but these tests have low clinical sensitivity for patients with paucibacillary TB disease. Our goal was to evaluate the clinical performance of a newly developed assay that can rapidly diagnose active TB cases by direct detection of Mtb -derived antigens in patients' blood samples.
