74786-5Influenza virus B Yamagata lineage RNA [Presence] in Specimen by NAA with probe detectionActive

Term Description

For the qualitative assay of influenza virus type B viral RNA. In the upper respiratory tract clinical specimens to include: nasopharyngeal swabs, nasal swabs, throat swabs, nasal aspirates, nasal washes and dual nasopharyngeal/throat swabs. Possible lower respiratory tract specimens include bronchoalveolar lavage, bronchial washings, tracheal aspirate, sputum, and lung tissue from patients with signs and symptoms of respiratory infection. This assay identifies the genetic lineage of human influenza B viruses B/Yamagata. This term was developed for, but not limited in use to, the CDC Human Influenza Virus Real-Time RT-PCR Diagnostic Panel.

Part Description

LP182338-6   Influenza virus B Yamagata lineage
Influenza B viruses can be separated into two major lineages, B/Victoria and B/Yamagata. Recent studies have shown that the two major lineages may differ in terms of epidemiology and risk of secondary infection. One study found that patients with confirmed influenza B Victoria lineage infections were significantly younger compared to patients infected with the Yamagata lineage.[PMID:25034374] A separate study found that Victoria-lineage viruses were associated with a significantly higher risk of secondary infection among patients' household contacts who were 15 years old or younger than among those older than 15, but the same did not hold true for Yamagata-lineage viruses.[PMID:26400854] Studies have also shown that genetically distinct lineages like B/Victoria/2/87 can cocirculate in the population and that the reassortment among these strains plays a role in generating the genetic diversity of influenza B viruses.

Change Reason
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.
