Specimens were tested for PRRS virus by real-time reverse transcriptase polymerase chain reaction (RT-PCR) with two commercial agent-specific assays, report Dr Karen M. Harmon and colleagues at Iowa State University in a paper published recently in Journal of Swine Health and Production.

Result discrepancy between the two tests was confirmed by conventional RT-PCR, sequencing, or both on six of 423 clinical cases. Neither assay detected every positive case.
