A polymerase chain reaction (PCR) test detects genetic material from a pathogen or abnormal cell sample. Ways of collecting samples include a nasal swab, a saliva swab, or taking a sample of blood.

Once the concept of PCR popped into Kary Mullis’ head in 1983 it wasn’t long before scientists realized they had a revolutionary technology in their hands. Because now they could take the smallest ...

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, ...

Polymerase chain reaction (PCR) and rapid (antigen) tests for COVID-19 both involve taking a swab. Results for a PCR test take longer, as it needs to go to a laboratory. It is more costly but tends to ...

COVID-19 tests are in greater demand than ever, and new data about the Omicron variant can make picking and using different types of tests confusing. Molecular tests for COVID-19, like the "RT-PCR" ...

In vitro diagnostics (IVD) is an umbrella term for tests conducted on blood or tissue samples to detect diseases, determine the efficacy of novel or established treatments, and monitor health.

Researchers at Columbia Engineering and Rover Diagnostics, both at Columbia University, New York, NY, have teamed up to develop a low-cost, photonics-based portable platform that gives RT-PCR results ...

New COVID-19 restrictions for international travel and other activities are fueling consumer demand for highly accurate polymerase chain reaction, or PCR, tests with rapid turnaround times. Some ...

Scientists consider polymerase chain reaction, or PCR, tests a highly reliable tool for diagnosing COVID-19. But social media posts are misrepresenting a recent Centers for Disease Control and ...
