Eligibility
Key inclusion criteria
* Mtb-positive, rifampicin-resistant respiratory specimen identified on Xpert MTB/RIF Ultra
Minimum age
No limit
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
* Residual SR-sputum mix not retained or not found
* Patient previously included in the study

Exclusion for diagnostic accuracy and time-to-result endpoints:

* Insufficient residual SR-sputum mix remaining for Xpert MTB/XDR (<2 ml)
* Xpert MTB/XDR unsuccessful
* No second / follow-up specimen received
* Second / follow-up specimen culture-negative, contaminated or not available
* Reference standard uninterpretable (phenotyping or WGS)

* Where phenotypic susceptibility testing results are uninterpretable, specimens will still be included in WGS comparison
* Where WGS results are uninterpretable, specimens will still be included in phenotypic susceptibility testing comparison
