After specimen processing, the resuspended pellet may be used for various tests as per the laboratory policy or national guidelines recommended for TB diagnosis such as:

 

  • Inoculation of sediments in Mycobacterium Growth Indicator Tube (MGIT) broth (Liquid media) and or solid media for primary culture isolation
  • Subculture a loopful on a Brain Heart Infusion (BHI) Agar plate for contamination check
  • Concentrated smear of processed specimen can be prepared if not prepared earlier, for a microscopy smear
  • DNA extraction for Line Probe Assay

 

Transfer the remaining sediment into 2 mL labelled cryovials and store at 2-8⁰C for repeat or additional testing.
