Much confusion exists about testing for SARS-CoV-2, the virus that causes the disease COVID-19. For instance, you may have heard of PCR as a method, but what is PCR, and how does it differ from ...

Polymerase chain reaction (PCR) tests, which amplify tiny snippets of nucleic acids in a biological sample to a level that they can be more easily identified, became a household name during the ...

Last week, I was about to go on a date, and because I'm severely immunocompromised, we agreed he would take a COVID test ...

Since the emergence of COVID-19 in late 2019, the gold standard in testing for the disease has been a nuclear-derived technique: real-time reverse transcription–polymerase chain reaction, or real-time ...

People with asymptomatic or mild illness generally test negative after nine days. A polymerase chain reaction (PCR) test can ...

While many countries have used real time RT–PCR for diagnosing other diseases, such as the Ebola virus and Zika virus, many need support in adapting this method for the COVID-19 virus, as well as in ...

PCR, or Polymerase Chain Reaction, is a revolutionary molecular biology technique that allows for the rapid amplification of specific DNA sequences. It is an essential tool in various fields, ...

But despite the exciting potential of PCR for many fields, the current system underpinning commercial tests can be unfeasible, Chun contends. PCR systems are expensive, so most manufacturers rent ...

PCR is a mainstay in diagnostics, but whether a sample is collected at a clinic or at home, such tests require sending a sample to a lab and then waiting for results. A new FDA authorized over-the ...

HealthTrackRx, the nation's leading provider of next-morning molecular diagnostics, today announced the development of a PCR test for Avian Influenza A (H5N1), created in partnership with the U.S.
