PCR analysis is usually but not always done in a laboratory. Once a covidSHIELD saliva sample reaches the laboratory, scientists drop it into a hot-water bath to kill any existing virus and ...

Tokyo — Researchers in Japan announced "game changing" research this week that found simple saliva tests for COVID-19 are just as reliable as the widely used, but more complicated and ...

Emerging research suggests saliva-based PCR tests may indeed offer the earliest opportunity to detect omicron. However, early studies offer a more messy picture for at-home rapid antigen tests.

Coronavirus saliva tests are a new type of PCR diagnostic for COVID-19. Saliva testing “does depend on standard PCR technology, and it does require some manual labor in order to move it through ...

Non-invasive saliva-based tests exist, but they also rely on the slow and specialized RT-PCR approach. A similar method called reverse transcription loop-mediated isothermal amplification (RT-LAMP ...

In the present prospective cohort study, researchers developed an automated, PCR-based service to detect SARS-CoV-2 from saliva samples and enable surveillance of asymptomatic community residents.

Non-invasive saliva-based tests exist, but they also rely on the slow and specialized RT-PCR approach. A similar method called reverse transcription loop-mediated isothermal amplification (RT-LAMP) ...

But on Saturday, the entire Saxvy family, including wife Anita and daughter Leah, did a much less invasive PCR test in Toronto. This one involved spitting into a cup and feeding their saliva into ...

Two alternatives — real-time polymerase-chain-reaction (PCR)–based testing of a liquid-saliva or dried-saliva specimen obtained at birth — have been developed. A total of 177 of 34,989 ...
