Clinical Evaluation of the Truenat Point-of-care Tuberculosis Diagnostic Test

The Truenat MTB (including both MTB and MTB Plus) and the MTB-RIF Dx reflex assays (Molbio Diagnostics; Bangalore, India) utilize chip-based real-time micro-PCR for detection of tuberculosis (TB) and rifampicin (RIF) resistance from DNA extracted (on a separate device) from sputum samples. The Truenat MTB assay targets a single copy gene while the MTB Plus assay combines detection of a single copy and multi-copy gene.
