Comparative analysis of sensitivity and specificity of PCR assay and conventional antibiotic sensitivity test
| Conventional sensitivity test | Total | ||
|---|---|---|---|
| Resistant | Sensitive | ||
| PCR assay | |||
| Resistant | 24 | 0 | 24 |
| Sensitive | 0 | 335 | 335 |
| Total | 24 | 335 | 359 |
Sensitivity = 24/(0 + 24) × 100 = 100%
Specificity = 335/(0 + 335) × 100 = 100%
Positive predictive value = 24/(0 + 24) × 100 = 100%
Negative predictive value = 335/(0 + 335) × 100 = 100%
