A research team from the Pohang University of Science and Technology (South Korea) has jointly developed a technology that allows anyone to easily and quickly diagnose the COVID-19 based on the RNA sequence of the virus.
This technology can diagnose infections in only 30 minutes, avoiding contact with infected patients as much as possible. The biggest benefit is that a diagnostic kit can be developed in a week, even if a new infectious disease other than COVID-19 appears.
The PCR molecular test currently used for the diagnosis of COVID-19 has a very high precision, but involves a complex preparation process to extract or refine the virus. It is not suitable for use in small farming or fishing villages, or in screening clinics at airports or coaches, as it requires a expensive equipment as well as qualified experts.
He ARN It is a nucleic acid that mediates genetic information or participates in the control of gene expression. The researchers designed the test equipment to produce the binding reaction nucleic acid to show fluorescence only when the ARN COVID-19 is present. Therefore, the virus can be detected immediately without any preparation process with high sensitivity in a short time. And it is as accurate as the current PCR diagnostic method.
Using this technology, the research team found the RNA of the SARS-CoV-2 virus, the cause of COVID-19, from a real sample of a patient in about 30 minutes. In addition, five pathogenic viruses and bacterial RNAs were detected that demonstrated the usefulness of the kit to detect pathogens other than COVID-19.
Another great advantage of the technology is the ease of creating the diagnostic device that can be developed in a simple, portable and Easy to use. If this method is introduced, it not only allows ‘in situ’ diagnosis before going to the screening clinic or being hospitalized, but also enables a more proactive response to COVID-19 by complementing the current centralized diagnostic system.
