Influenza virus B Ag [Presence] in Upper respiratory specimen by Rapid immunoassay
Active
Term Description
This term was created for, but is not limited in use to, the Influenza B part of the bioMerieux bioNexia Influenza A+B test, which is intended for the qualitative detection and differentiation of Influenza type A and type B antigens in human nasopharyngeal samples. The results of the bioNexia assay should be read ten minutes after the sample is applied to the sample well.
Part Description
LP14240-3 Influenza virus B
Influenza virus from the family Orthomyxoviridae are enveloped negative-strand RNA viruses with segmented genomes containing seven to eight gene segments. Of the five genera in the family, only influenza A virus (IAV), influenza B and C viruses are medically relevant to humans. Influenza A and B viruses have a similar structure whereby these viruses each contain eight discrete single-stranded RNA gene segments, each encoding at least one protein. While having a close phylogenetic relationship, influenza virus types A and B manifest very differently. While IAV infects birds, humans and other mammals, influenza B only infects humans and seals. Although both viruses cause human respiratory infection seasonally in temperate climate regions and more continually in the tropics, influenza B is normally less prevalent and causes less severe disease than IAV viruses. Research is ongoing to determine the evolutionary and epidemiological factors that shape the genetic diversity of influenza B virus. PMID: 25812763 [CDC:flu/about/viruses/types]

- Version 2.77 (MAJ)
- Change Reason
- Release 2.77: SYSTEM: Updated to standardize the representation of "Respiratory system specimen" in the System subhierarchy across LOINC; Release 2.70: SYSTEM: Updated from "Nph" to make the LOINC term consistent with the original intent to represent a manufacturer's test covering NPH washes and nose swabs, as well as to make it consistent across panel usage.; Previous Releases: Corrected System from "Nasopharynx", which is used for LOINC clinical terms, to "Nph", which is the form used for LOINC lab terms.; 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.; The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.
