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 ...

Accurate and rapid diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been instrumental in mitigating viral spread during the coronavirus disease 2019 (COVID-19) ...

Since the emergence of COVID-19 in late 2019, the gold standard in testing for the disease has been a nuclear-derived technique: real-time reverse transcription–polymerase chain reaction, or real-time ...

At-home COVID-19 tests have become an easy way to self-diagnose. But current tests have drawbacks, such as the length of time it takes to get an answer, or how accurately the test can identify a ...

Total RNA from frozen tissues was extracted using TRIZOL reagent. RNA was extracted from formalin-fixed, paraffin-embedded tissues by digestion with proteinase K before the acid-phenol:chloroform ...

Polymerase chain reaction, or PCR, was developed to identify a small fragment of a virus and create multiple copies, making detection easier. PCR is the gold standard in testing for COVID-19 and other ...

Single-tube multiplex RT–PCR was developed for the simultaneous detection of Cucumber mosaic virus and Piper yellow mottle virus in black pepper. PCR primers designed for amplifying 650 bp from the ...

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 ...

Today, Autonomous Medical Devices Incorporated (AMDI) announced its submission to the US Food and Drug Administration (FDA) ...
