50701-2Influenza virus A H1 Ag [Presence] in Isolate by ImmunofluorescenceActive

Part Description

LP35168-1   Influenza virus A H1
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.

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.
