- LPA, line probe assay
- MGIT DST, Mycobacterial Growth Indicator Tube
- RIFS, rifampicin susceptible; RIFR, rifampicin resistant
- INHS, isoniazid susceptible; INHR, isoniazid resistant
- * No result was due to lack of growth from the frozen primary isolate (15), isolation of non-tuberculous mycobacteria (1), contamination (2) or unavailability of frozen isolate for MGIT DST (8).
- Indeterminate results included are those remaining without an interpretable result after repeat testing.
