PRRSV North American strain IgG Ab [Titer] in Serum by Immunofluorescence 85525-4
LOINC Code
| LOINC code | 85525-4 | ||
|---|---|---|---|
| name | PRRSV North American strain IgG Ab [Titer] 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 examination using a fluorescent microscope for characteristic patterns of fluorescent staining. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Porcine reproductive and respiratory syndrome virus North American strain Ab.IgG | ||
| property | Titr = Dilution Factor (Titer) | ||
| 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 | SemiQn | ||
| 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). | ||
