75377-2Dengue virus NS1 Ag [Presence] in Serum, Plasma or Blood by Rapid immunoassayActive

Term Description

Dengue virus non-structural protein 1 (NS1 Ag) rapid test kits are available from manufacturers in various countries including the United States, Germany, and China. As of 2013, no Dengue virus NS1 Ag rapid test kits are approved for use in the United States. This term was based on, but not limited in use to, the BIOCREDIT Rapidgen Dengue NS1 Ag test kit that uses a lateral flow chromatographic immunoassay. Testing can be done in under 20 minutes on serum, plasma or whole blood. This is a screening test and reactive specimens must be confirmed with alternative methods.

Part Description

LP184362-4   Dengue virus NS1
Dengue viruses are in the Flavivirus genus of the Flaviviridae family. Flaviviruses are enveloped, single-strand RNA viruses. The genomic RNA encodes three structural proteins, C (core protein), M (membrane protein), and E (envelope protein). The nonstructural (NS) proteins are NS1, NS2a, NS2b, NS3, NS4a, NS4b, and NS5. NS1 is a glycoprotein that appears to be essential for virus viability but has no established biological activity. NS1 is produced in both membrane-associated and secreted forms. The NS1 antigen is present at high concentrations patients during the early clinical phase of the disease. [PMID: 16988003] Source: Regenstrief LOINC, PMID: 16988003

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.; 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.
Order vs. Observation
