Diagnostic performance of serological tests in elk.

Assay	Sensitivitya	Specificityb	Accuracy
CervidTB STAT-PAK	82% (28/34)	93% (131/141)	91% (159/175)
DPP VetTB	79% (27/34)	98% (138/141)	94% (165/175)

^aElk were considered positive for bovine TB if either M. bovis was isolated upon culture of lesions or mycobacteriosis compatible lesions were detected upon microscopic examination of gross lesions.

^bSera from noninfected and SCT-negative elk were obtained from the APHIS, NVSL bovine TB serum bank for evaluation of test specificity.
