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 ...

PCR swab tests that look for viral RNA have become the gold standard for identifying infection with the SARS-CoV-2 virus, but their results aren't 100% accurate. Researchers report that testing for ...

Because of its high accuracy, laboratory-based polymerase chain reaction (PCR) testing is the gold standard for infectious disease diagnostics. However, PCR technology requires highly trained staff ...

Researchers have modified a gene editing tool to serve as a highly sensitive diagnostic test for the presence of the SARS-CoV-2 virus. An engineered CRISPR-based method that finds RNA from SARS-CoV-2, ...

Researchers at the University of Washington in Seattle have created a new test for COVID-19 they say combines the speed of an over-the-counter antigen test with the accuracy of a PCR test. The Harmony ...

At the start of the SARS-CoV-2 pandemic people who felt unwell had to join long queues for lab-based PCR tests and then wait for two days to learn if they were infected with the COVID-19 virus or not.
