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 ...

For more than 30 years, polymerase chain reaction (PCR) has been the gold standard in molecular diagnostic testing, detecting genetic material, such as those from a virus or from human DNA. But PCR, ...

Viruses that cause measles and the common cold do not produce false-positive COVID-19 reverse transcriptase polymerase chain reaction (RT-PCR) tests, contrary to posts circulating widely online. A ...

The accuracy of the RT-PCR test depends on timing; tests are best given within 10 days of COVID-19 symptom development. As the COVID-19 pandemic continues to spread across the country, many nurse ...

One of the best ways to figure out how far a virus like COVID-19 has spread in a community is to test for it. This step-by-step guide explains how coronavirus swab-the-nose-and-throat tests work, and ...

Social media users are falsely claiming that there is no accurate test to detect the COVID-19 virus and therefore no accurate test to detect the Delta variant. Examples can be seen here and here. Sign ...

In a recent study posted to the Lancet preprint* server, researchers assessed the utility of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) rapid antigen testing (RAT) for patient triage ...

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 ...
