Receiver operation area under the curve of actionable vs. non-actionable results of MTBDRsl on Ultra diamond cartridge extract done on DR-TB clinical sputa to determine a CTmin threshold at which this approach is not feasible. MTBDRsl yields actionable results on cartridge extract from Ultra at a CTmin threshold of <25.4 with a sensitivity of 97% (87.1–99.9; 95% CI) and specificity of 100% (54.9–100; 95% CI) respectively.
