Scientists say Covid PCR tests could be replaced with an almost-instant test that uses X-rays.
Researchers say that the new artificial intelligence (AI) technology has an accuracy of 98% and could provide results within minutes.
PCR tests take around two hours to show a positive or negative result.
The AI technology uses an algorithm to analyse the X-ray images and make a quick diagnosis, according to The Mirror.
A team from the University of West of Scotland (UWS) is behind the project, which is led by Professor Naeem Ramzan. The team includes Gabriel Okolo and Dr Stamos Katsigiannis.
In his latest update, Professor Ramzan said: "There has long been a need for a quick and reliable tool that can detect Covid-19, and this has become even more true with the upswing of the Omicron variant.
"Several countries are unable to carry out large numbers of covid tests because of limited diagnosis tools, but this technique utilises easily accessible technology to quickly detect the virus.
"Covid-19 symptoms are not visible in x-rays during the early stages of infection, so it is important to note that the technology cannot fully replace PCR tests.
"However, it can still play an important role in curtailing the viruses spread especially when PCR tests are not readily available.
"It could prove to be crucial, and potentially life-saving, when diagnosing severe cases of the virus, helping determine what treatment may be required."
Professor Milan Radosavljevic, vice-principal of research, innovation and engagement at UWS described the research as "game-changing".
He added: "It's another example of the purposeful, impactful work that has gone on at UWS throughout the pandemic, making a genuine difference in the fight against Covid-19.
"I am incredibly proud of the drive and innovation demonstrated by our internationally renowned academics, as they strive to find solutions to urgent global problems."
