In the ongoing global fight against coronavirus disease 2019 (COVID-19), the sample preparation process for real-time reverse transcription polymerase chain reaction (rRT-PCR) faces challenges due to ...

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 ...

This study elaborates on the design, fabrication, and data analysis details of SPEED, a recently proposed smartphone-based digital polymerase chain reaction (dPCR) device. The dPCR chips incorporate ...

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 ...

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 ...

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.

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.

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 ...

The CDC in July announced its intent to withdraw an emergency use request for a protocol for PCR testing for COVID-19. The withdrawal would become effective Dec. 31, 2021. But that was because of the ...

Recall, if you dare, life in December 2020. America had just approved Covid-19 vaccines for use, but most of us wouldn’t get a shot for months. Instead, amid the second surge of coronavirus cases, ...
