Using cut off values mentioned in Table 1 diagnostic performance of each peptide ELISA was estimated. “+” Indicates positive and “−” indicates negative

^aThe percent accuracy was calculated using formula: % Accuracy IBVP1 = (201/224) × 100 = 89.73%. Results of each peptide ELISA were compared with whole viral antigen based commercial ELISA kit (IDEXX Laboratories, USA)
