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.

LP7565-7   Saliva
Saliva is produced primarily by the parotid, submaxillary, and sublingual glands. It is secreted at the rate of 0-3 milliliters per minute which is affected by various factors including anxiety, hydration and hunger. Oral fluid is broadly used to test for drugs of abuse in employment and forensic settings, and is especially useful since it is difficult to adulterate, is quick and is non-invasive. Oral fluid is used to test a variety of analytes, including to test alcohol, HIV and other antibodies, therapeutic drugs and steroids, but its primary use is to test for drugs of abuse including amphetamines, cocaine and metabolites, opioids, methadone, cannabis and heroin.
