Expensive equipment, qualified experts and a price in case of doing it on your own that is not affordable in this current economic recession. The current PCR test for the diagnosis of COVID-19 has a very high accuracy, 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 airport or coach screening clinics. It’s not (fast enough). It’s not cheap. It is effective but not efficient in the reality in which we live.
Detect Covid-19 in 30 minutes
For this reason, and given that we are in the middle of the second wave of the global pandemic that we are experiencing, 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 COVID-19 based on the RNA sequence of the virus.
This technology can diagnose infections in just 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.
Through the RNA of the virus
RNA is a nucleic acid that mediates genetic information or participates in the control of gene expression. The Korean researchers have designed their technology around a test kit to produce the nucleic acid binding reaction to show fluorescence only when COVID-19 RNA is present.. Therefore, the virus can be detected immediately, without any preparation process, which means speed of detection and low cost of the test.
The doubt of some will be, “And if you do it that fast, won’t it be less accurate?“No, because in fact this method turns out to be 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 an actual sample from a patient in about 30 minutes.
In the test it was detected up to 5 pathogenic viruses and bacterial RNAs 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 user-friendly way.
Detect the virus faster and cheaper
This method not only allows ‘on-the-spot’ 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. Of course, implementing it globally would be a good tool to get ahead of the Coronavirus, something not necessary, but essential now that The WHO points out that 10% of humanity has been infected with Covid-19.
