SARS-CoV-2 (COVID-19) RNA [Presence] in Respiratory system specimen by Sequencing
Active
Term Description
Qualitative detection of nucleic acid from SARS coronavirus 2 (SARS-CoV-2) in respiratory specimens by sequencing methods, such as next generation sequencing (NGS), also known as high-throughput sequencing (HTS). Testing is performed for the diagnosis of COVID-19.

Part Descriptions
LP150045-5 Sequencing
Sequencing is a method used to determine the sequence of individual genes, larger genetic regions (i.e. clusters of genes or operons), full chromosomes or entire genomes. Historically, most sequencing has been performed using the chain termination method developed by Frederick Sanger in 1977. PMID: 271968 Sequencing technologies have improved dramatically, making them cheaper, faster, and more accurate. Next-generation sequencing (NGS), also known as high-throughput sequencing, deep sequencing, and second-generation sequencing, is a type of technology that uses parallel sequencing of multiple small fragments of DNA to determine sequence. This "high-throughput" technology has increased the speed and amount of DNA sequenced at a significantly reduced cost. PMID: 18576944 Several NGS platforms (ie, sequencing instruments and associated reagents) have been developed. Third-generation sequencing is another methodology currently under development that uses parallel sequencing similar to NGS. In contrast to NGS, third-generation sequencing uses single DNA molecules rather than amplified DNA as a template. PMID: 20858600

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.

- Change Reason
- Release 2.75: SYSTEM: There are 2 similar system's in LOINC: 1- Respiratory system 2- Respiratory specimen Due to an applied logic, the display in the System axis for 1 is Respiratory (adjective) without specification of sample, specimen, or other specific noun, while 2 is displayed fully as Respiratory specimen. Therefore for now we replaced 1 with Respiratory system specimen, which will affect 83 term. The result is replacing "Respiratory" with "Respiratory system specimen". This is the short approach. The bigger project is to potentially merge data that has either 1 or 2 together. This is a project to pass by the laboratory committee and will involve about 1500 concepts.;
