In South Korea, the researchers at the Pohang University of Science & Technology (POSTECH) found a new way of detecting coronavirus in just 30 minutes. The scientist claimed that the result through this method is as accurate as of the current PCR diagnostic test.
According to reports, this new way of detecting coronavirus is based on the RNA sequence of the virus which can quickly and easily do the test. The SENSR technology will reduce “the stress on one single testing location and avoiding contact with infected patients as much as possible,” according to reports.
As per the research published in the journal the Nature Biomedical Engineering, the diagnostic kit will be developed within a week.
The test done will produce a nucleic acid binding reaction which will show fluorescence only when COVID-19 RNA is present.
The virus can be detected immediately without any preparation process with high sensitivity in a short time, the study showed. RNA is a nucleic acid that mediates genetic information or is involved in controlling the expression of genes.
In just 30 minutes, the researchers found the SARS-CoV-2 virus RNA using this new technology. Moreover, researchers said that pathogens apart from what responsible for COVID-19 were also detected by this kit.
The researchers noted that the currently used PCR molecular test for COVID-19 diagnosis is very accurate but it includes a complex preparation process to refine or extract the virus.
The test is not suitable for use in small farming or fishing villages, or airport or drive-thru screening clinics as it requires expensive equipment as well as skilled experts, the scientists said.
The method not only allows onsite diagnosis before going to the screening clinic or being hospitalised but also allows for a more proactive response to COVID-19 by supplementing the current centralized diagnostic system.
“This method is a fast and simple diagnostic technology which can accurately analyse the RNA without having to treat a patient’s sample,” said POSTECH Professor Jeong Wook Lee.
