name
Parainfluenza virus 2 Ag [Presence] in Nasopharynx by Immunofluorescence
description
This term was created for, but not limited in use to, the Light Diagnostics, Respiratory Panel Viral Screening and Identification IFA kit, for the qualitative identification of Adenovirus, Influenza A, Influenza B, Parainfluenza 1, 2, 3, and Respiratory Syncytial virus in cell culture, which uses an indirect immunofluorescence technique for identifying virus in infected cell cultures.

Fully-Specified Name
component
Parainfluenza virus 2 Ag
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.
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).

Associated Observations
LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations.
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
