80589-5Influenza virus A H1 HA gene [Presence] in Nasopharynx by NAA with probe detectionActive

Term Description

Detection of targeted nucleic acid sequences in the Influenza virus A H1 hemagglutinin (HA) gene by PCR-based methods. This term was created for, but not limited in use to, the Verigene® Respiratory Pathogens Flex Nucleic Acid Test (RP Flex), a multiplexed, qualitative test for the detection and identification of multiple viral and bacterial genetic virulence markers from nasopharyngeal swab specimens.

Part Description

LP206572-2   Influenza virus A H1 HA gene
The influenza virus A (FLUVA) genome is composed of eight gene segments (PB2, PB1, PA, HA, NP, NA, M, NS1) that code for 11 proteins. Two of the genes, hemagglutinin (HA) and neuraminidase (NA), determine the structure of the two primary surface proteins of influenza viruses. The HA and NA gene sequences are used to determine the Influenza virus subtype. Currently there are 16 subtypes of HA and 9 subtypes of NA known, but only H 1, 2 and 3, and N 1 and 2 are commonly found in humans.[PMID:17458769] The M gene segment, which encodes two matrix proteins (M1 and M2), may also be used as a target in PCR-based assays for detection of FLUVA in various specimens.
