There are three different ways to test for COVID-19: PCR tests, antigen tests and antibody tests. Each method is best for a different stage of COVID-19 infection. Used in sequence, all three ...

some test kits allow people to collect their own sample at home and then send it off to a lab for PCR testing. These are different than the rapid at-home antigen tests that return results on the spot.

PCR is a common technique in medical and biological research labs, and there are many applications. However, a “PCR test” typically refers to a quick, accurate diagnostic test for the early ...

The US Food and Drug Administration has authorized use of both PCR tests and rapid antigen tests in laboratory-based or point-of-care settings (such as a physician’s office, urgent care facility ...

Because of the way the Omicron variant has mutated, some PCR lab tests can provide a good hint that it's around. The clue is not definitive, but it can help scientists determine which tests to ...

The other is a molecular test, which is often a polymerase chain reaction (PCR) test. PCR tests involve a lab process that can detect the genetic material of SARS-CoV-2, the virus that causes ...

"CDC has just announced they will revoke the emergency use authorization of the RT-PCR tests first introduced in 2/20," reads a July 25 post, which goes on to quote from the agency's lab directive ...

Chinese scientists say they have developed a new coronavirus test that is as accurate as a PCR lab test but gives results within four minutes. Polymerase chain reaction (PCR) tests are widely ...

Researchers at Imperial College London say they have developed a novel lab-on-a-chip infection test that could provide ... of the polymerase chain reaction (PCR) on bodily fluids, feces, or ...

In the past, scientists had to grow live pathogens in a lab when testing for viruses or parasites, but PCR tests have since replaced some of those culture-based methods. (Fabrizio Bensch/Reuters ...
