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 ...

COVID-19 is commonly diagnosed by quantitative fluorescence real-time reverse transcriptase-polymerase chain reaction (qRT-PCR) (1, 2). The test is the sequential action of two enzymes–an ...

The COVID-19 pandemic yielded important advances in testing for respiratory viruses, but it also exposed important unmet needs in screening to prevent the spread of infections in high-risk settings.

Polymerase chain reaction (PCR) tests have become routine because of the COVID-19 pandemic, with more than a million PCR tests being carried out daily in the United States alone. What are now commonly ...

At-home COVID-19 tests have become an easy way to self-diagnose. But current tests have drawbacks, such as the length of time it takes to get an answer, or how accurately the test can identify a ...

Over the past four years, many of us have become accustomed to a swab up the nose to test for COVID-19, using at-home rapid antigen tests or the more accurate clinic-provided PCR tests with a longer ...

Researchers have developed a new test for COVID-19 that combines the speed of over-the-counter antigen tests with the accuracy of PCR tests that are processed in medical labs and hospitals.

Respiratory syncytial virus (RSV) was detected easiest when using reverse transcription polymerase chain reaction (RT-PCR) tests in a pediatric population. Reverse transcription polymerase chain ...
