  • a Data were extracted from the multiplex assay for these individual antigens.

  • b The sensitivity of the Anigen lateral-flow kit is 90.0% compared to that of culture-confirmed positives, and it is 85.1% compared to that of skin test-confirmed positives according to the manufacturer's instructions.

  • c The specificity of the Anigen lateral-flow kit is 98.6% compared to that of skin test-confirmed negative animals according to the manufacturer's instructions.
