A new study led by University of Manchester researchers has contributed to significant strides in asthma diagnosis. The Rapid Access Diagnostics in Asthma (RADicA) research clinic aims to identify the most effective combination of breathing tests to confirm whether someone has asthma.

The RADicA study has been honoured with a prestigious accolade at The University of Manchester’s 2025 Making a Difference Awards, taking home the title for ‘Outstanding Benefit to Society Through Research’. Led by a dedicated team from the Faculty of Biology, Medicine and Health; Professors Angela Simpson, Stephen Fowler and Clare Murray, the study is reshaping how asthma is diagnosed in the UK. 

Asthma currently affects 1 in 12 adults nationwide, yet misdiagnosis remains alarmingly common, costing the NHS more than £132 million each year. Backed by the National Institute for Health and Care Research (NIHR) Manchester Biomedical Research Centre (BRC), the RADicA project has worked closely with local patients to design innovative, patient-centred approaches to asthma diagnosis, bringing meaningful change to people’s lives and healthcare systems alike. 

Based at Wythenshawe Hospital, part of Manchester University NHS Foundation Trust, the team have worked with over 30 GP practices serving local communities to identify participants. To date, more than 400 adults and children have been involved in the programme.  

Currently, diagnosis is a complex process, requiring patients to undergo several tests before a precise decision can be made. The RADicA study has developed new tests and processes to better enable doctors to make accurate diagnoses. 

RADicA has made a significant impact across both clinical practice and research. Patients who participated have seen a marked improvement in the accuracy of their diagnoses. Additionally, findings have helped shape new national asthma guidelines published earlier this year. 

“This recognition is a tribute to the incredible dedication and teamwork behind RADicA,” said Professor Fowler. “Professor Murray, Professor Simpson, and I are grateful to the research practitioners, clinicians, and the entire delivery team whose efforts have driven real, national change in how asthma is diagnosed, and their commitment has been transformative.”
