A new test method developed by a research team led by the Department of Diagnostic Biotechnology of University College London can directly identify infectious diseases from the surface of a mobile phone with an accuracy comparable to that of an antigen test: “Eliminate the discomfort on the surface of the mobile phone. Tampon nose Pharyngeal, because screening is a priority for the emergence of new variants, it opens up new diagnostic possibilities.”
A new Covid test method developed by a research team led by University College London’s Chilean startup Diagnosis Biotech allows the detection of coronavirus infection through swab analysis of the surface of a smartphone.Is called Phone Screen Test (PoST), This program allows you to easily and accurately analyze samples obtained by rubbing cotton swabs directly on the phone screen, thereby eliminating the discomfort of nasopharyngeal swabs.In addition, the developer explained that this new test method increases the diagnostic potential by requiring Less than a minute Sampling does not require medical personnel to sample, which is convenient for large-scale use.
The application was published in Electronic lifeIt has been shown to be as reliable as the lateral flow antigen test currently used for the qualitative detection of Sars-Cov-2 antigen in nasal and oropharyngeal swabs. “We proved that the PoST method detects the presence of a virus 81-100% of people with a high viral load are on their phones, Showing that this method can effectively identify individuals who can spread infection“.
It was also found that the method is reliable in recognition Main variants of concern (Alpha, Beta, and Gamma), the resulting population “A new smart, smart phone-based non-invasive test alternative that is cost-effective and easy to implement in population screening“leftover”Absolute priority“Considering the emergence of new virus variants and the different availability of vaccines against the new coronavirus worldwide.
“The only effective way to stop the spread of the coronavirus is to regularly test as many people as possible -Rodrigo Young of the Institute of Ophthalmology, University College London and the lead author of the study said. This does not always happen, especially in low-income countries, because it is too expensive and difficult to implement.In this sense, the PoST method not only makes population screening easier, but also Used to control the outbreak of new viruses And avoid future epidemics“.
