Calculation of sensitivity and specificity of the rapid IC kit assay compared to RT‐PCR assay in CSF specimens
| RT‐PCR results of CSF samples | Sum | |||
|---|---|---|---|---|
| + | – | |||
| Rapid IC test kit results of CSF samples | + | 15 | 2 | 17 |
| – | 1 | 2 | 3 | |
| Sum | 16 | 4 | 20 | |
Note: Per cent observed agreement = (15 + 2)/20 = 85%; sensitivity = 15/16 = 93.8%; specificity = 2/4 = 50%; Kappa = 0.48 (moderate).
