86219-3

LOINC code 86219-3 identifies "Porcine epidemic diarrhea virus IgG Ab [Titer] in Serum by Immunofluorescence". This term is used to report the titer of IgG antibodies against Porcine epidemic virus (PEDv) based on immunofluorescence staining pattern. IgG antibodies to PEDv are typically be detected 7 to 14 days following exposure. Samples are compared to positive and negative controls. If cells fluoresce brilliant blue-green color against a background of non-infected cells, then the sample is considered positive; If cells do not fluoresce brilliantly but may show background non-specific fluorescence, then the sample is considered negative.; If cells fluoresce weakly and is not background fluorescence, then the sample is considered suspect. If high background fluorescence does not allow for an accurate determination to be made, then the sample is considered inconclusive. Titers that are equal to or greater than 1:40 are considered positive.

This code measures Porcine epidemic diarrhea virus Ab.IgG in Ser. It belongs to the MICRO class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
