The laboratory is NABL accredited, fully equipped to offer complete diagnostic services for diagnosis of tuberculosis (TB), Non-tubercular Mycobacteria (NTM), and drug resistance to various anti-tubercular drugs by molecular as well as conventional methods. The laboratory offers microscopy, culture (both liquid and solid), PCR and Gene-Xpert for diagnosis of TB and NTM. In addition, the conventional drug sensitivity testing in liquid and solid culture media, Gene-Xpert, Line Probe Assay are available for detecting resistance to both first line and second line drugs. The laboratory is equipped with state of art molecular typing techniques for TB. All the techniques are quality assured.
The laboratory carries out research under several funded schemes (Extramural funding support for Whole Genome Sequencing, Early Bactericidal Activity, Therapeutic Drug Monitoring, Point of Care tests (Aptamer based), Novel biomarkers, Rapid molecular drug resistance detection, Molecular Epidemiology of MDR-TB).
