A gaggle of Chilean scientists developed a brand new methodology to detect COVID-19. It’s to make u na PCR check to display screen your digital units and, in response to the examine, the consequence can be 90% equal to that of a nasopharyngeal check.
The benefit of this new methodology, known as PoST for its acronym in English (Telephone Display Testing, in Spanish: check of the telephone display screen) is that it’s a lot much less invasive and that it could have a decrease value .
It is very important be aware that this new methodology is simpler in these sufferers with a excessive viral load, since in low prevalence settings it is extremely doubtless that false optimistic outcomes will seem, in response to the World Well being Group (WHO) .
How does this new process work?
“The swab is handed over the cellphone display screen as an alternative of the nostril after which it’s analyzed as with a standard PCR to detect if there are traces of the virus RNA,” defined Alejandra Lavanderos, one of many collaborating researchers.
The examine was led by Chilean physician Rodrigo Yung, who works on the World College of London (UCL). It was additionally revealed within the British common science journal eLife .
About 1,200 individuals underwent the experiment, the place they did a traditional PCR check and one other with the brand new PoST methodology. On this method checked the specificity of the evaluation. Alternatively, the process was helpful for detecting the “worrying” variants : Delta, Alhpa or Gamma, which have grow to be a problem for the world on account of their excessive contagion capability.
When you meet all the required necessities, scientists will search approval from the suitable well being authorities as an alternative choice to conventional checks.
