Table 3 Technical Comparison between different methods and MTT based method.
Method | Media requirement per test | Time required | MIC determination | Complexity |
|---|---|---|---|---|
Agar dilution Method 9 | 300 ml | 24 h | Yes | More tedious with higher media requirement |
Easy MIC Test 9 | 20 ml | 24 h | Yes | Required Easy MIC strips which increased the cost |
MTT based Method | 300 μl | 7 h | Yes | Very less media required, rapid and simple |
Oxacillin Screen Agar 9 | 20 ml | 24 h | No | Cannot detect borderline resistant strains |
Oxacillin Disc Diffusion 9 | 20 ml | 24 h | No | Gives false positive results |
PCR for mec A 14 | – | 12–16 h | No | Set up not available in all laboratories |
