Covid PCR tests could be replaced by an X-ray with results given 'in minutes'

Scientists believe they have developed an almost-instant Covid diagnosis test that will use X-rays instead of PCR tests with an accuracy of 98%.

The Artificial Intelligence programme would offer results within minutes and would be a big boost to healthcare staff, it has been claimed.

Experts at the University of the West of Scotland say the speed of results would aid the frontline battle against the deadly bug.

A PCR test typically takes around two hours to inform of a positive or negative result.

But the Artificial Intelligence programme detects the virus much faster and the idea would boost hospital care around the world.

An AI process uses an algorithm to analyse visual imagery and make a quick diagnosis.

Professor Naeem Ramzan led the three-person team behind the project, which also involved Gabriel Okolo and Dr Stamos Katsigiannis.

In his latest update, he wrote: "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, hailed the significance of the development.

"This is potentially game-changing research," he said.

"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."
