Xpert result a | Culture result b | Chest X-ray c | TB treatment history d | Number of cases |
---|---|---|---|---|
MTB detected | MTB Growth | Any | Any | 130 e |
MTB not detected | MTB Growth | Abnormal | Any | 48 |
MTB detected | No growth | Abnormal | No history | 34 |
MTB detected | No growth | Abnormal | < 2 years | 2 |
MTB detected | No growth | Abnormal | > 2 years | 3 |
MTB detected | Contaminated/missing/NTM | Abnormal | No history | 4 |
MTB detected | Contaminated/missing/NTM | Abnormal | < 2 years | 0 |
MTB detected | Contaminated/missing/NTM | Abnormal | > 2 years | 0 |
Total number | 221 |
MTB: Mycobacterium tuberculosis; NTM: Nontuberculous mycobacteria
a Combined result of two Xpert tests on different sputum sample (M1 and M1b). Does include participants with one (n = 55) and two (n = 118) Xpert results of MTB detected
b Final culture result, which is the MGIT result unless the MGIT culture was contaminated and the LJ culture result was either no growth or MTB+, then the LJ result was taken (n = 1)
c Final expert panel conclusion, abnormal meaning chest X-ray with any abnormality suggesting active TB disease
d Treatment history as reported by the participant in the in-depth interview
e Five of these patients were on TB treatment at the time of the survey, and five reported to have TB treatment history within two years preceding the survey.
