The phone screen, as useful for taking COVID tests as your own nose


Invasive tests for COVID could be replaced with samples taken from a mobile phone screen, with British researchers discovering enough virus to get a conclusive result.

Sticking the dreaded stick to take PCR tests deep into your nose may not be necessary if you are one of those people who uses a smartphone frequently.

Called PoST (Phone Screen Testing), even method to give results with a level of accuracy comparable to a conventionally harvested PCR test.



According to the research team at the UCL Institute of Ophthalmology, the telephone screen test method (PoST) identified the presence of COVID virus in more than 80% of cases, the level of accuracy being similar to lateral antigen tests, but without applying a swab to the throat. or in the nose.

Diagnosis Biotech teams have already begun using the new test method with company employees and school students in Chile, trying to determine its viability. There are even plans to create mobile test stations, where COVID samples are taken directly from the screen of mobile phones and the results end up there, like SMS messages.

If all goes according to plan, the widespread application of this method and even the development of specialized COVID test kits will not be long in coming. Certainly, those interested in testing COVID with the phone will find it easier than those willing to accept the introduction of a stick for sampling directly from the nasal cavity.
