Qualitative and quantitative associations between tuberculosis detection modalities
(A) Detection of Mycobacterium tuberculosis by blood Xpert Ultra in participants with missing sputum and urine samples. (B) Intersections between M tuberculosis bloodstream infection diagnostics. Blood Xpert Ultra was positive in 111 (69%) of 162 patients who had tuberculosis recovered from their first blood culture. Out of 113 patients who also had a second tuberculosis blood culture 50 (44%) were positive; blood Xpert Ultra was positive in 35 of 50 of these. Agreement (measured by Cohen's kappa) between blood Xpert Ultra and blood culture one was the same as agreement between pairs of blood cultures in the same patient. Xpert Ultra=Xpert MTB/RIF Ultra. LAM=lipoarabinomannan.
