Diagnostic Molecular Mycobacteriology in Regions With Low Tuberculosis Endemicity: Combining Real-time PCR Assays for Detection of Multiple Mycobacterial Pathogens With Line Probe Assays for Identification of Resistance Mutations

Molecular assays have not yet been able to replace time-consuming culture-based methods in clinical mycobacteriology.Using 6875 clinical samples and a study period of 35 months we evaluated the use of PCR-based assays to establish a diagnostic workflow with a fast time-to-result of 1–2 days, for 1. detection of Mycobacterium tuberculosis complex (MTB), 2. detection and identification of nontuberculous mycobacteria (NTM), and 3. identification of...
