Researchers often call the polymerase chain reaction test – known as the PCR test – "the gold standard" for detecting the COVID-19 virus. The test is considered highly reliable and effective, and it ...

Molecular tests are far superior to rapid antigen tests—and now you can get them for home use. Amanda Blum is a freelancer who writes about smart home technology, gardening, and food preservation.

Real-time PCR plays a foundational role in gene expression studies, disease analysis, and molecular diagnostics. However, success depends on precise reaction setup, optimized assays, and accurate ...

Rapid COVID tests are convenient and easy to use because you can take them at home. But it's important to know how to interpret their results, when you should take another rapid test and when you ...

If you had COVID-19 symptoms in 2020, you probably would have masked up and braved a visit to a laboratory, doctor’s office, or clinic to get a polymerase chain reaction (PCR) test. A health care ...

The test requires a certain amount of viral material to be captured by a nasal swab or saliva samples. PCR, or polymerase chain reaction, technology is the most accurate way to test for SARS-CoV-2. It ...

Polymerase chain reaction (PCR) test kits for COVID-19 use what’s known as gene cloning – not reproductive cloning – to detect the presence or absence of the SARS-CoV-2 virus, but social media posts ...

Extraordinary achievement promises to help turn the tide against the COVID 19 pandemic, Knox Henderson writes. XPhyto Therapeutics Corp. (XPHY:CSE; XPHYF:OTCQB; 4XT:FSE) is a Canadian life sciences ...
