The accuracy of the RT-PCR test depends on timing; tests are best given within 10 days of COVID-19 symptom development. As the COVID-19 pandemic continues to spread across the country, many nurse ...

Respiratory syncytial virus (RSV) was detected easiest when using reverse transcription polymerase chain reaction (RT-PCR) tests in a pediatric population. Reverse transcription polymerase chain ...

What is real-time quantitative PCR? qPCR uses one of two methods to detect the changes to DNA amplification: use of fluorescent dyes or sequence-specific DNA probes. qPCR is normally performed in a ...

Real-time PCR, or quantitative qPCR, is a commonly used molecular biology lab technique to determine the actual amount of PCR product at a given cycle. For quantitative reverse transcription PCR ...

To execute COVID-19 testing strategies effectively, labs need to procure reliable components of the workflow without interruption – from reagents to equipment and consumables at the scale they need, ...

How does RT-LAMP work? The methodology for RT-LAMP was based on the mechanism behind auto cycling strand displacement DNA synthesis. A polymerase carries out the reaction, and the polymerase has high ...

One of the best ways to figure out how far a virus like COVID-19 has spread in a community is to test for it. This step-by-step guide explains how coronavirus swab-the-nose-and-throat tests work, and ...
