COVID-19 PCR (Polymerase chain reaction)
The COVID-19 RT-PCR test is a real-time reverse transcription polymerase chain reaction (rRT-PCR) test for the qualitative detection of nucleic acid from SARS-CoV-2 in upper and lower respiratory specimens (such as nasopharyngeal or oropharyngeal swabs, sputum, lower respiratory tract aspirates, bronchoalveolar lavage, and nasopharyngeal wash/aspirate) collected from individuals suspected of COVID-19 by their healthcare provider (HCP), as well as upper respiratory specimens (such as nasopharyngeal or oropharyngeal swabs, nasal swabs, or mid-turbinate swabs) collected from any individual, including for testing of individuals without symptoms or other reasons to suspect COVID-19 infection.
Polymerase chain reaction (PCR) is a method widely used to rapidly make millions to billions of copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detail. PCR was invented in 1984 by the American biochemist Kary Mullis at Cetus Corporation.
RT-PCR is a laboratory-based technique used for detecting and comparing the levels of ribonucleic acid (RNA) and the surface proteins in a sample, particularly samples with limited quantities of RNA.
CEO SUMMARY: Last spring, a histopathology lab in Illinois began running molecular COVID-19 tests and decided the clinical side of the lab would focus exclusively on PCR testing for COVID-19. The challenge was how to access a reliable source of test kits, reagents, and supplies to o…
CEO SUMMARY: In a remarkable example of prescience, informed by decades-long experience in clinical lab testing and past epidemics, the president of NorDx Laboratories in Maine saw the December news accounts of a widespread outbreak of a new respiratory disease in China. He warned h…
