If you had COVID-19 symptoms in 2020, you probably would have masked up and braved a visit to a laboratory, doctor’s office, or clinic to get a polymerase chain reaction (PCR) test. A health care ...

Researchers often call the polymerase chain reaction test – known as the PCR test – "the gold standard" for detecting the COVID-19 virus. The test is considered highly reliable and effective, and it ...

No one is really excited about a nasal swab or spitting in a tube, but now that testing has become the next front in the war against COVID-19, rapid tests (now available for free through ...

For any American wondering if they have Covid-19, there are two kinds of tests available: polymerase chain reaction (PCR) and rapid antigen (sometimes just called “rapid tests”). The two tests work in ...

Molecular tests are far superior to rapid antigen tests—and now you can get them for home use. Amanda Blum is a freelancer who writes about smart home technology, gardening, and food preservation.

Real-time PCR plays a foundational role in gene expression studies, disease analysis, and molecular diagnostics. However, success depends on precise reaction setup, optimized assays, and accurate ...

With COVID case rates once again surging across the DMV, and many employers/schools tightening their return-to-building policies, rapid tests have become the hot-button item to secure this winter.

PCR tests are one of the most accurate forms of testing for the coronavirus. PCR stand for polymerase chain reaction test. There are many different reasons why you may need to book a covid test, for ...

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 ...

A false claim on social media cites instructional leaflets in COVID-19 tests as evidence that they aren't accurate. The posts claim a list of 52 viruses "can cause a PCR test to give false positives." ...

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 ...
