Comparison of MODS, MABA, and SSCP in evaluating MTB sensitivity to RIF
| Response | No. (%) of specimens showing RIF susceptibility by
|
||
|---|---|---|---|
| MABA | MODS | SSCP | |
| Resistance | 11 (79) | 14 (100)a | 10 (71) |
| Sensitivity | 3 (21) | 0 (0) | 4 (29) |
| Total | 14 (100) | 14 (100) | 14 (100) |
The cutoff level used to determine RIF resistance was 0.5 μg/ml. When a concentration of 1.00 μg/ml was used, two of the three strains initially classified by MODS as resistant were reclassified as sensitive.
