Comparison of the recomLine VZV prototype with wcELISA in healthy blood donors
| Result | wc ELISA | recomLine VZV | ||
|---|---|---|---|---|
| IgM | IgG | IgM | IgG | |
| Posa | 1 | 95 | 1 | 97 |
| Incb | 4 | 3 | 0 | 0 |
| Negc | 95 | 2 | 99 | 3 |
| Specificity | Gold standard | 98.08d - 100.0e % | ||
| Sensitivity | 95.15e - 97.96d % | |||
NOTE. Data are no. of serum samples unless otherwise indicated.
a Pos: positive
b Inc: inconclusive
c Neg: negative
To calculate sensitivity and specificity, the inconclusive results were grouped as dnegative or as epositive.
RecomLine VZV strips were considered as positive when the intensity of the ORF68 band was higher than the cut-off band control.
