| description | The Porcine Reproductive and Respiratory Syndrome Virus (PRRSv) genome contains at least eight opens reading frames (ORFs). ORF 5 contains about 600bp and is the least conserved region of PRRSV. Samples taken from infected pigs, as well as virus isolates, can be tested to determine the genetic sequence of the PRRSv. Examining the portion of the RNA that is most likely to mutate helps in determining how closely linked one PRRSv is to another, and can also be used to differentiate field strains from vaccine strains. This assay targets the ORF5 gene for Ingelvac MLV like PRRSV strain. Sample types for this test may include serum, fresh tissue, oral fluids or swabs, nasal swabs and environmental specimens like feed or feed pre-mix. | |

| property | ThreshNum = Threshold Number | |
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | |

| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | |
