Scientists come up with a test that detects corona using a swab from a mobile phone screen


Scientists have come up with a new way to test for the Corona virus, by taking swabs (PoST) from the screen of an individual’s smartphone, and this method of testing is less expensive, and it is equally accurate as other methods of examining the presence of the virus in the respiratory tract of an individual.


The report, published by “timesofindia”, today, Sunday, confirmed that the new examination method is not taking samples from the individual’s nose or throat, which is usually done in the case of RT-PCR and Rapid Antigen, but through the screen of his mobile phone, as many confirmed Studies that our smartphones contain millions of viruses and bacteria, when we take them to the bathroom, hold them with our hands, or place them on an unclean surface, and pathogens stick to the cell phone, and when we hold the phone and then touch our mouth, nose or eyes with the same hands, microorganisms enter Invisible to our members.


The report indicated that in the case of the Corona virus, when people cough, sneeze or talk, the droplets they expel carry pathogens that settle on the surfaces around them, and the new study conducted by scientists shows that when a person is infected with the Corona virus, this can be detected from the screen of his mobile phone.


How does this test work?

The report indicated that how to conduct the new test, in which samples are collected from a phone screen using swabs like those used in sampling from the nasopharynx, are then fed into saline and subjected to a regular PCR test.


The team, led by researchers from University College London, conducted this test on 540 individuals before they came to the final results, taking the swab that underwent both the regular PCR test, and the PoST phone swabs The tests were done in different laboratories by independent teams, and the researchers discovered that the phone test was Able to detect 81.3% to 100% of people with high viral load.


Of all the people, 51 people tested positive for coronavirus in the RT-PCR test, and these people also tested positive in the phone test, while the researchers explained that this new screening method helped detect 100% positive cases in individuals with a viral load. High.


How this examination can be useful

The report confirmed that the way to check the phone to detect the presence of the virus is cheaper, faster and also accurate, it may be easy to conduct mass tests to detect the presence of the virus, especially when cases of Corona virus infection rise significantly.


The researchers presented this method of screening as an excellent method for mass testing of people, as we know that some people are asymptomatic and spread the virus without their knowledge, and with this method of testing, it may be easy to conduct regular screening at a larger level to detect the presence of the virus.
