PCR and rapid tests each work differently. The PCR (which stands for polymerase chain reaction) test looks for genetic material from the virus, while the rapid test looks for viral antigens, a ...

PCR tests detect the genetic material from the virus, while rapid antigen tests detect specific proteins from the coronavirus. Here is the best time to use each, and how to use them to gather ...

COVID tests are in short supply, but it's still possible to find some, including for free. Here's what to look for, and how to get an accurate result.

Dr. Geoff Baird with UW Medicine has a simple formula for weighing the two main COVID test types: PCR (polymerase chain reaction) and rapid antigen.

The eccentric scientist behind the ‘gold standard’ COVID-19 test Bombastic biochemist Kary Mullis invented PCR, a tool that redefined genetic science, while driving in 1983. That was only the ...

He realized he could repurpose some of those small PCR machines to test for the coronavirus by using a different sample-processing cartridge.

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 ...
