In a recent study posted to the medRxiv* preprint server, researchers examined sample collection practices, epidemiological characteristics, and cycle threshold (Ct) values for polymerase chain ...

Polymerase chain reaction (PCR) and rapid (antigen) tests for COVID-19 both involve taking a swab. Results for a PCR test take longer, as it needs to go to a laboratory. It is more costly but tends to ...

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 ...

When creating a PCR protocol, users normally concentrate on the template DNA, reaction mix (buffer, dNTPs, taq polymerase), primers, probes, and the thermocycler, which is the main instrument used to ...

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.

A polymerase chain reaction (PCR) test detects genetic material from a pathogen or abnormal cell sample. Ways of collecting samples include a nasal swab, a saliva swab, or taking a sample of blood.
