Field trial of the specifi city of an ELISA test for PRRS (IDEXX HERDCHEK® PRRS 2XR) high specificity confirmed, but varying behaviour according to the age of the animals

The laboratory diagnosis of the Porcine Respiratory and Reproductive Syndrome (PRRS) is mainly based on the use of serological ELISA tests and PCR diagnostics. The aim of this study was to assess the specificity of a commercial ELISA test. In particular, the specificity of the test is compared in two different subpopulations: adult breeding sows and young pigs.   Vincent Auvigne1, Jean-Louis Pinsard2, Herve Gourgues3 1.
