Under the National Tuberculosis Elimination Programme (NTEP), many labs are established at the regional level within states for providing Culture and Drug Susceptibility Testing (C&DST) facilities for presumptive TB/DRTB and for TB/DRTB patients.

C&DST laboratories are mostly located in intermediate reference laboratories (IRLs) or medical colleges.
There are 42 C&DST laboratories established under the programme in different geographies.
Dedicated human resources are provided for the laboratories under the programme.
Districts are linked with laboratories for providing facilities for Culture and DST using:
- Phenotypic Methods (Solid – Lowenstein Jensen (LJ), and Liquid Culture – Mycobacteria Growth Indicator Tube (MGIT))
- Genotypic technology (Line Probe Assay (LPA) and Cartridge Based Nucleic Acid Amplification Test (CBNAAT))
