112294-4 Respiratory syncytial virus Ag [Presence] in Nose by Rapid immunoassay

Part Descriptions

LP14244-5   Respiratory syncytial virus
Human respiratory syncytial virus (RSV), a negative-sense, single-stranded RNA virus of the family Paramyxoviridae, causes upper respiratory tract infections and bronchiolitis, an infection of the small airways that can cause wheezing and respiratory distress. Infants, especially those that were born prematurely, are particularly susceptible, and RSV bronchiolitis is a common cause of hospitalization for infants during the winter months. Certain groups of high-risk infants may be given palivizumab, a recombinant monoclonal antibody to RSV, as prophylaxis against RSV infection. Source: Regenstrief LOINC

97097-0 SARS-CoV-2 (COVID-19) Ag [Presence] in Upper respiratory specimen by Rapid immunoassay

Term Description

Qualitative detection of SARS coronavirus 2 (SARS-CoV-2) antigen in upper respiratory specimens, such as nasopharyngeal swabs, by rapid immunoassay methods. Testing is performed for the diagnosis of Coronavirus Disease 2019 (COVID-19).

Part Descriptions

LP417540-4   SARS coronavirus 2
The 2019 Novel Coronavirus (2019-nCoV) is a coronavirus first identified as the cause of a respiratory illness outbreak in Wuhan, China. Initially, the outbreak was linked to a large seafood and animal market and thought to only be spread by animal to person contact. Within a short time, a growing number of patients who had not been exposed to animal markets were diagnosed with the infection, indicating person-to-person transmission. As of January 2020, infections with 2019-nCoV had been reported internationally due to confirmed cases in travelers from Wuhan. Overall, clinical symptoms appear milder than SARS Coronavirus (SARS-CoV) and Middle East Respiratory Syndrome (MERS) Coronavirus (MERS-CoV) infections as do the fatality rate and transmissibility. PMID: 31953166 Reported illnesses range from minor or no respiratory symptoms to severe acute respiratory illness and death.

The full genome of the 2019-nCoV was first posted by Chinese health authorities in GenBank, the NIH genetic sequence database, and in the Global Initiative on Sharing All Influenza Data (GISAI) portal. This facilitated detection of the virus globally with subsequent sequences being nearly identical, suggesting a single, recent emergence from a virus related to bat coronaviruses and the SARS coronavirus.

72367-6 Influenza virus A+B Ag [Presence] in Nose by Rapid immunoassay

Term Description

This test is intended to encode results for tests which detect but do not differentiate Influenza type A and B viral antigens from nasal swab or nasal wash specimen in 10 minutes or less. It is typified by the Quidel's QuickVue Influenza test.

Part Descriptions

LP14402-9   Influenza virus A+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. Aquatic birds harboring avian IAV are the likely natural reservoir for all known IAV subtypes and are probably the original source of all human pandemic IAV strains. IAV maintained in wild birds have been associated with stable host switch events to novel hosts including most often to domestic poultry but also to horses, swine, toothed whales and humans, among other species. Although influenza virus B has been isolated from seals, type B is isolated almost always from humans. Influenza C virus has been isolated from pigs and dogs. While influenza B and C virus also cause illness in humans, host switch events and high mutation rates among IAV types causes respiratory infections in humans ranging from asymptomatic to fatal and are the cause of the influenza pandemics in the 20th and 21st centuries. Pandemics are attributed to "novel" viruses which possess a viral hemagglutinin (HA) to which humans do not have immunity. PMID: 25812763 [CDC:flu/about/viruses/types] Source: Regenstrief LOINC

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.
