Melbourne , Aug 14:
Scientists have developed a new low-cost nasal swab test which can accurately diagnose the presence of SARS-CoV-2 virus that causes COVID-19 in just 20 minutes. This new test uses only one tube and involves only a single step, making it more efficient and lower cost than many of the current tests.
The findings, published in the Journal of Medical Microbiology, show the test called N1-STOP-LAMP, is 100 per cent accurate in diagnosing samples containing SARS-CoV-2 at high loads.
The rapid molecular test is highly accurate and easy to use, making it a prime candidate for use in settings with limited testing capabilities, according to the researchers.
“In the race to control the COVID-19 pandemic, access to rapid, precision diagnostics is key,” said Tim Stinear, a professor at the University of Melbourne in Australia.
“We have developed an alternative COVID-19 molecular test that can be readily deployed in settings where access to standard laboratory testing is limited or where ultra-rapid result turnaround times are needed,” Stinear said. It’s a robust diagnostic test for the specific and rapid detection of COVID-19, but it’s important to note that it trades some detection sensitivity for speed and ease-of-use, they said.
