Part Description

LP417599-0   SARS coronavirus 2 N gene
The Severe acute respiratory syndrome (SARS) coronavirus 2 (SARS-CoV-2), first known as 2019 Novel Coronavirus (2019-nCoV), was first identified as the cause of a respiratory illness outbreak, later defined as Coronavirus Disease 2019 (COVID-19), in Wuhan, China. The full genome of the SARS-CoV-2 that causes COVID-19 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. Real time Reverse Transcription-Polymerase Chain Reaction (rRT-PCR) tests targeting regions within genes, including RdRp, S, N, M, and E genes, specific to SARS-CoV-2 have been developed by the Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO) and others for the diagnosis of COVID-19. Some assays only detect SARS-CoV-2 and other assays detect other strains (e.g. SARS-CoV) that are genetically similar.[CDC: coronavirus/2019-ncov][https://www.who.int/emergencies/diseases/novel-coronavirus-2019/technical-guidance/laboratory-guidance] Source: Regenstrief LOINC

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.;
