Arthritis diagnosis method can identify condition in just 10 minutes
New research suggests osteoarthritis and rheumatoid arthritis could be diagnosed and distinguished with an accuracy of over 94%.
It is estimated around 1.5 million people in Scotland live with arthritis and related conditions. Around half of Scots say they experience pain every single day.
However according to experts, a new method can now diagnose arthritis in just ten minutes by using bodily fluids. The results, published in scientific journal Small, also showed osteoarthritis and rheumatoid arthritis could be diagnosed and distinguished with an accuracy of over 94%.
The technology achieved over 95% accuracy in determining the severity of rheumatoid arthritis, reports the Mirror. More than half of all people over the age of 65 experience symptoms of osteoarthritis, according to previous research.
On the other hand, rheumatoid arthritis is known to be a serious chronic disease that affects around one in 100 people over the course of their lifetime.
Although osteoarthritis and rheumatoid arthritis are often mistakingly labelled as similar, scientists say they differ in both their causes and treatments, making accurate distinction at the early diagnosis stage "critically" important.
However until now, diagnosis has relied on X-rays, MRI scans, and blood tests, which are not only an expense and takes up a lot of time, but is also limited in its accuracy.
Dr Ho Sang Jung and his research team at the Korea Institute of Materials Science (KIMS), in collaboration with Seoul St. Mary's Hospital, developed the technology that enables the diagnosis of osteoarthritis and rheumatoid arthritis using synovial fluid, contained in human joints.
The researchers focused on the differences in the composition of metabolites - by-products of chemical processes occurring within the body - present in the fluid.
By analysing the metabolic differences, they developed a technology capable of distinguishing between osteoarthritis and rheumatoid arthritis within 10 minutes, as well as assessing the severity of rheumatoid arthritis.
The Korean team utilised Surface-Enhanced Raman Scattering (SERS) technology, a phenomenon in which the optical signals of molecules are amplified by several million times.
Dr Jung said: "This technology amplifies signals from trace molecules present in synovial fluid and, through a combination of AI-based analysis and mathematical algorithms, detects minute substances responsible for arthritis."
The team also developed a simple and rapid diagnostic method using a sensor composed of a sea urchin-shaped gold nanostructure formed on a paper surface with high moisture absorption, enabling efficient detection via body fluids.
In collaboration with Seoul St. Mary's Hospital, the research team conducted tests using the new technology on 120 patients.
The researchers say the findings show the technology not only significantly reduces the time and cost of arthritis diagnosis, but also ensures a high level of diagnostic accuracy.
Dr Jung, the lead researcher at KIMS, added: "If this technology is commercialised, it will not only aid in diagnosis but also be highly useful in monitoring treatment progress.
"We also plan to continue expanding our research to cover a wider range of diseases in the future."

Terminally ill Wrexham toddler visited by Peppa Pig
Earlier this year, Callie Shaw was tragically diagnosed, aged just 10 months, with a rhabdoid tumour - a rare and aggressive form of childhood cancer. She spent the next few months in Alder Hey to receive treatment. After undergoing four months of chemotherapy - things appeared to be going well and the tumour was shrinking in size. Callie Shaw and mum, Sarah (Image: Sarah Shaw) However, her family was given the devastating news last month following an MRI scan that Callie's cancer has spread to her lungs - and is now terminal. Callie was given a prognosis of four-six weeks. A GoFundMe page set up to support Callie's family at this very difficult time has raised over £7,000. With her first birthday spent during her time at Alder Hey, family and friends recently organised a party so she could celebrate properly. And on Monday (June 9), she received a surprise visit from Peppa Pig and Chase from Paw Petrol - her and her brother's favourite characters. (Image: Sarah Shaw) The visit was organised by Mold-based Blue Duo Events - which also donated 50 bags of candy floss for Callie's party. Blue Duo Events said on its Facebook page: "As a business, we felt there was more we could do – and this evening, we did just that. We surprised Callie with a visit from her two favourite characters, bringing smiles and joy to her and her family. One of our playful pups also joined in to surprise her little brother, making sure he felt just as special. (Image: Blue Duo Events) "Thank you, Sarah (Callie's mum) for allowing us to visit Callie at home and letting us be part of these precious moments. MORE NEWS: "The Blue Duo team are thinking of you all and sending love during this incredibly difficult time." Sarah Shaw said: "It was amazing to have Peppa Pig come and visit Callie. She absolutely adores Peppa Pig and it was really special. "I want to say a massive thank you to Blue Duo Events - you made memories that will last forever. It means so much to us."

Rise in suspected drug deaths in Glasgow this year
Latest figures from Police Scotland show there were 61 deaths in the Greater Glasgow division between January and March. It is a rise from the 50 deaths recorded for October to December last year. It means a 22% increase in the Glasgow area since the start of the year. READ NEXT:Hundreds of homeless refused accommodation in one month in Glasgow Across Scotland, there was also an increase in suspected deaths from 232 over the last three months of 2024 to 308 in the first three months of this year, a rise of 32%. The numbers of suspected drug deaths fluctuate and the most recent figures for both the Glasgow and Scottish totals are fewer than the same three months in 2024 For January to March 2024, there were 71 for Greater Glasgow and 320 across Scotland. The number of people dying from drug related deaths remains one of the highest in Europe and opposition politicians have said the government approach is not working. Annie Wells, Glasgow Conservative MSP highlighted the She said 'These devastating figures should be a source of shame for deluded SNP ministers, whose strategy to tackle drug deaths is clearly failing. 'They are completely detached from the reality of this national crisis which has spiralled to record levels on their watch.' She used the latest figures to argue the opening of the Safer Drug Consumption Facility in Glasgow is not making a difference. The centre opened in Janaury this year. Wells added: 'Nationalist politicians have been at pains to trumpet the opening of The Thistle in Glasgow as a game-changing solution, yet the number of Scots suspected to have tragically lost their lives to drugs has risen sharply since it opened. 'It is clear that facility is feeding addiction, rather than helping to treat addiction. "The public will be appalled that Neil Gray thinks more consumption rooms should get the green light while this flagship one is failing people so badly.' She instead urged MSPs and the Scottish Government to back the Tories Right to Recovery Bill at Holyrood. There have been 17 medical emergencies at the Thistle since it opened. The health secretary said last week had they not been at the centre they likely would have died. READ NEXT: 'Chancellor should have u-turned on winter fuel long ago' says SNP The Liberal Democrats, however, said more facilities like the Thistle are needed. Alex Cole-Hamilton, Scottish LibDem leader, said: 'One hundred people a month are dying in Scotland's drug deaths crisis. It is nothing short of a national tragedy. 'Drug misuse casts a long shadow across Scotland. 'Scottish Liberal Democrats would give our country the world-class drug services it deserves. 'From rolling out a nationwide network of safer consumption rooms to new drug checking facilities, it's time ministers listened to our calls.'

Suspected drug deaths in Scotland up by a third in three months
There were 308 such deaths over the period January to March, with this total up by 33% on the last three months of 2024. The figures come after the UK's first safer drugs consumption room, the Thistle centre in Glasgow, opened for a three-year pilot in January this year as part of Scottish Government efforts to reduce Scotland's drugs deaths. The report said that 'suspected drug deaths in Scotland remain at a high level' – with such cases up by 76 when compared to the final three months of 2024. READ MORE: Family 'utterly heartbroken' as man dies weeks after three-vehicle crash However, the Scottish Government report stressed that 'numbers of suspected drug deaths fluctuate from quarter to quarter', adding that 'care should be taken not to interpret movements between individual calendar quarters as indicative of any long-term trend'. And the data also showed a decrease in the number of suspected drugs deaths over the course of the year. There were 1053 suspected drugs deaths in the 12 months to March 2025 – meaning there were 166 (14%) fewer such deaths than in the 12 months to March 2024, when the total was 1219. With Scotland having had the highest rate of drugs related deaths in Europe, the Government has a 'national mission' to reduce the numbers losing their lives to drugs. Speaking as Tuesday's figures were published, Health Secretary Neil Gray (below) said: 'Every death is a tragedy and through our £250 million national mission we are determined to continue our efforts to reduce harm and deaths. My condolences go to anyone who has lost a loved one. ' (Image: PA) Gray added: 'While these figures show a quarter-on-quarter rise in suspected drug deaths, they also note a year-on-year fall. 'We want every person experiencing harm to be able to access the support they need. 'We are taking a wide range of evidence-based measures including opening the UK's first safer drug consumption facility pilot, working towards drug-checking facilities and widening access to treatment, residential rehabilitation and life-saving naloxone.' However, Scottish Conservative spokesperson for drugs, Annie Wells, hit out and said: 'These devastating figures should be a source of shame for deluded SNP ministers, whose strategy to tackle drug deaths is clearly failing.' The Tory MSP accused the Scottish Government of being 'completely detached from the reality of this national crisis which has spiralled to record levels on their watch'. She said that ministers had 'been at pains to trumpet the opening of The Thistle in Glasgow as a game-changing solution', but added that 'the number of Scots suspected to have tragically lost their lives to drugs has risen sharply since it opened'. Wells said: 'It is clear that facility is feeding addiction, rather than helping to treat addiction.' Scottish Liberal Democrat leader Alex Cole-Hamilton pointed out that '100 people a month are dying in Scotland's drug deaths crisis', saying this is 'nothing short of a national tragedy'. Adding that 'drug misuse casts a long shadow across Scotland', he said his party 'would give our country the world-class drug services it deserves'. Cole-Hamilton (below) added: 'From rolling out a nationwide network of safer consumption rooms to new drug-checking facilities, it's time ministers listened to our calls.' (Image: Ken Jack) The demand for action came as the Scottish Government's figures showed that the Greater Glasgow, Ayrshire and Lanarkshire police divisions had the highest number of suspected drugs deaths in the first three months of this year, with 61, 36 and 33 such fatalities in those areas respectively. Almost four out five (79%) of those who died were male, the figures showed while 63% of deaths occurred amongst those aged 35 to 54 years old – with this said to be 'broadly in line' with other quarters. However, there were nine suspected drugs deaths involving people aged under 25 in the period January to March, with this up from four such deaths in the final three months of 2024.
