From: Performance of the Genotype® MTBDRPlus resistance patternSamara, Russian Federation
Sputum AFB grading OR Previous anti-TB treatment | Unreadable GenoType® MTBDRplus patterns (N = 14) | Unusual (double) GenoType® MTBDRplus patterns (N = 39) |
|---|---|---|

1+ (n = 64) | 11 (17.2%) | 21 (32.8%) |
2+ (n = 60) | 2 (3.3%) | 12 (20.0%) |
3+ (n = 42) | 0 | 6 (14.3%) |
