| name | PRRSV European strain IgG Ab [Presence] in Serum by Immunofluorescence | ||
| description | The IFA method for antibody testing of Porcine reproductive and respiratory syndrome (PRRS) is fast and less expensive than other methods but can result in false positives so should be confirmed by virus isolation (VI) or RT-PCR methods. [http://lib.dr.iastate.edu/ cgi/viewcontent.cgi?article=4013&context=etd] It uses sample and control serums that are diluted and incubated on the PRRSV infected cells followed by florescent microscopic examination for characteristic patterns of fluorescent staining. Antibody can be detected in experimenally infected pigs 7 to 10 days post inoculation. Serum samples are screened at a 1:20 dilution. (USDA). | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Porcine reproductive and respiratory syndrome virus European strain Ab.IgG | ||
| property | PrThr = Present or threshold: The Property PrThr stands for “Presence or Threshold”, meaning either a) the actual presence or absence of an analyte, or b) that the amount of analyte detected is over some predetermined threshold. | ||
| 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. | ||
| system | Ser = Serum | ||
| scale | Ord = Ordinal: Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive. | ||
| method | IF = Immune Fluorescence: Encompasses DFA, IFA, FA. Usually applies to cells and smears examined microscopically so that both the “where” and the “what” can be assessed, but can also be used on fluids in a way similar to ELISA. Does not include Cell binding assays (see CBA IFA above). | ||
