Oxford University scientists’ AI diagnostic test accurately identifies known respiratory viruses in minutes

  • Breakthrough in diagnostics testing allows ‘facial recognition for germs’
  • Collaboration with John Radcliffe Hospital used AI to determine respiratory viruses and totally different strains with an accuracy of >97% in underneath 5 minutes
  • Founders search additional funding to assist revolutionise respiratory an infection diagnostics with higher management of viral outbreaks, assuaging strain on the NHS

February sixth, 2023 – Oxford, United KingdomNicolas Shiaelis and Dr Nicole Robb, Oxford College scientists and co-founders of well being tech firm Pictura Bio, have developed a world-first diagnostic, take a look at powered by synthetic intelligence, that may determine identified respiratory viruses similar to influenza and COVID-19 inside 5 minutes from only one nasal or throat swab.

Present checks are both lab based mostly and time consuming or quick and fewer correct. They’re additionally restricted, as an example, a lateral stream take a look at solely checks for one an infection. This implies diseases are unfold as contaminated folks anticipate outcomes, or as a result of they’re unaware they’re contaminated. These findings, revealed in peer-reviewed, scientific journal ACS Nano, exhibit how machine studying can considerably enhance the effectivity, accuracy and time taken to not solely determine several types of viruses, but additionally differentiate between strains. This might assist higher management the unfold of respiratory infections and alleviate strain on the NHS and healthcare workers while decreasing medical waste.


Shiaelis and Robb collaborated with the John Radcliffe Hospital to judge a brand new methodology that makes use of AI software program to determine viruses. The bottom-breaking testing expertise combines molecular labelling, pc imaginative and prescient and machine studying to create a common diagnostic imaging platform that appears instantly at a affected person pattern and might determine which pathogen is current in a matter of seconds. Very like facial recognition software program, however for germs.

Preliminary analysis demonstrated that this take a look at might determine the COVID-19 virus in affected person samples. However to develop this additional, they needed to find out if the take a look at could possibly be used to diagnose a number of respiratory infections.

Within the research, researchers started by labelling viruses in over 200 medical samples from John Radcliffe Hospital. Photos of labelled samples have been captured and processed by customized machine-learning software program that’s educated to recognise particular viruses by analysing their fluorescence labels, which present up otherwise for each virus as a result of their floor dimension, form and chemistry differ. The outcomes present the expertise is ready to quickly determine differing types and strains of respiratory viruses, together with flu and COVID-19, inside 5 minutes and with >97% accuracy.

The scientists fashioned Pictura Bio to additional develop this expertise and at the moment are searching for additional funding to speed up improvement and get it to the entrance line of healthcare.

Dr Nicole Robb, scientist and co-founder of Pictura Bio, feedback: “Circumstances of respiratory infections in winter 2022/23 have hit record-breaking highs, rising the variety of folks searching for medical assist. This mixed with the COVID-19 backlog, workers shortages, tighter budgets and an ageing inhabitants places the NHS and its workforce underneath immense and unsustainable strain.

“Pictura Bio’s simplified methodology of diagnostic testing is faster and cheaper, correct and future proof than every other checks presently obtainable. If we wish to detect a brand new virus, all we have to do is retrain the software program to recognise it, reasonably than develop a complete new take a look at. Our findings exhibit the potential for this methodology to revolutionise viral diagnostics and our skill to manage the unfold of respiratory diseases.”

Lead-author of the publication, co-founder and DPhil post-grad researcher on the College of Oxford, Nicolas Shiaelis, added: “It’s inevitable that different COVID-like viruses will emerge. This reinforces the necessity for extra superior diagnostic testing expertise in order that we will cut back the impression of latest viruses on public well being and the NHS.”

The expertise is now licensed by Pictura Bio which goals to show the strategy right into a diagnostic take a look at by making a devoted imager and single-use cartridge to be used in point-of-care testing, with restricted enter from the consumer. The staff can even develop the variety of viruses that the fashions are educated on and can finally begin taking a look at different pathogens, similar to micro organism and fungi, in respiratory samples, blood and urine.

About Pictura Bio
Pictura Bio is a health-tech firm that has developed the world’s first one-minute pathogen recognition platform. The software program, like facial recognition for pathogens, is a common testing platform, powered by AI, to offer correct, digital imaging-based identification of infectious illness. The innovation encompasses two patented improvements – PIC-ID and IRIS. PIC-ID coats the lipid membrane while IRIS, a deep studying neural community, concurrently analyses and classifies pathogens. It’s a essentially totally different manner of figuring out ALL infectious brokers and the corporate’s imaginative and prescient is to have a Lab in a Field for one minute testing on desktops in hospitals, GP surgical procedures and pharmacies all over the world.

Pictura Bio’s options drive sooner, easier and cheaper testing than resource-consuming molecular diagnostics, altering how we deal with illness. The expertise will allow healthcare choice makers to revolutionise well being care as we all know it – bolstering the struggle towards antimicrobial resistance, decreasing medical waste and limiting virus publicity.

PIC-ID and IRIS – the expertise
The Pictura Bio staff is specializing in packaging its PIC-ID expertise right into a easy desktop ‘lab in a field’, named IRIS (Immediate Recognition Identification System) across the dimension of a home microwave, comprising a single-purpose high-powered fluorescent microscope and picture seize and processing expertise. This expertise has reached proof of idea and is protected by patents and the staff is now within the means of constructing the expertise to scale this product for wider availability & adoption within the medical neighborhood. Right now, PIC-ID is educated to identify enveloped viruses from respiratory samples, however the future holds boundless potential for the way pathogens in samples are recognised.

The Neural Community is the database that IRIS checks towards to determine a pathogen. This course of ensures that as new checks and pathogens are discovered by the community, it may be repeatedly rolled through a software program replace, as a substitute of requiring new panels and the infrastructure to go together with it.
