100343-3Influenza virus B RNA [Presence] in Saliva (oral fluid) by NAA with probe detectionActive

Term Description

This is a real-time RT-PCR for qualitative detection Influenza B virus RNA in saliva specimens. The test could be a single assay or part of a multiplex panel to detect Influenza B virus and other pathogens. The test could target a single Influenza B virus gene (e.g., the NS1 gene) or it could target multiple genes.

Part Descriptions

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.

LP7565-7   Saliva
Saliva is produced primarily by the parotid, submaxillary, and sublingual glands. It is secreted at the rate of 0-3 milliliters per minute which is affected by various factors including anxiety, hydration and hunger. Oral fluid is broadly used to test for drugs of abuse in employment and forensic settings, and is especially useful since it is difficult to adulterate, is quick and is non-invasive. Oral fluid is used to test a variety of analytes, including to test alcohol, HIV and other antibodies, therapeutic drugs and steroids, but its primary use is to test for drugs of abuse including amphetamines, cocaine and metabolites, opioids, methadone, cannabis and heroin.[PMID:17268583] Source: Regenstrief LOINC
