  • In automated systems, tubes are read continuously and flagged when positive.  Performing acid-fast bacteria (AFB) smear with Zeihl-Neelsen (ZN) staining determines the next steps.

  •  All MGIT-negative tubes at the end of the incubation period should be visually checked for evidence of growth before being discarded.

  • ZN staining should be performed on growth as soon as possible. After staining, culture should be handled according to the results.
