TABLE 2.
Estimates of Se and Sp for the CHEKIT ELISA and the C-ELISA based on subset of juvenile animals and compared to the cVNT as the gold standarda
| cVNT result | CHEKIT result | No. of animals with C-ELISA result that was:
|
|
|---|---|---|---|
| + | − | ||
| Seropositiveb | + | 46 | 2 |
| − | 136 | 134 | |
| Seronegativec | + | 2 | 4 |
| − | 17 | 310 | |
a
Total number of animals tested, 651. The recommended cutoffs of 30% for the CHEKIT ELISA and 50% for the C-ELISA were used.
b
Se of CHEKIT ELISA = 0.151; Se of C-ELISA = 0.572; kappa value of 0.212 between CHEKIT and C-ELISA results.
c
Sp of CHEKIT ELISA = 0.982; Sp of C-ELISA = 0.942; kappa value of 0.136 between CHEKIT and C-ELISA results.
