A pioneering study conducted in Birmingham has been hailed as a ‘game changer’ in the early detection of type 1 diabetes among children. The Early Surveillance for Autoimmune Diabetes (Elsa) trial, led by the University of Birmingham and co-funded by Diabetes UK and Breakthrough T1D, has demonstrated that simple finger-prick blood tests can identify the disease before symptoms appear.
The trial invited children aged three to thirteen to provide finger-prick blood samples. Those found to be at risk underwent further blood and sugar tolerance testing. Out of 17,931 tests, over 200 children were identified with markers indicating an increased risk of developing type 1 diabetes.
The study will now enter a second phase, extending testing to children aged two to seventeen. Alongside this expansion, NHS clinics will be established to provide ongoing support for families whose children are identified as at risk.

Currently, more than 25% of children are not diagnosed with type 1 diabetes until they experience diabetic ketoacidosis (DKA), a potentially fatal emergency condition requiring immediate hospital care. Early detection through this trial could drastically reduce such cases. It also opens the door to new immunotherapy treatments that can delay insulin dependency by years.
Professor Neil Hanley, Pro-Vice-Chancellor and Head of the College of Medicine and Health at the University of Birmingham and Executive Director of Birmingham Health Partners, described the findings as transformative. “This trial shows we can spare countless children the trauma of an emergency diagnosis, provide early support, and offer access to revolutionary treatments that could delay or even prevent type 1 diabetes,” he said.
Professor Hanley praised Dr Parth Narendran and his team for their work, emphasizing the power of collaboration between world-class clinicians and scientists in Birmingham. He highlighted the city’s exceptional innovation infrastructure and diverse community as key factors driving progress in diagnostics, therapeutics, and clinical care.
West Midlands Mayor Richard Parker also expressed pride in the research. “The University of Birmingham’s work is improving children’s lives by developing more effective early screening for type 1 diabetes,” he said. Mayor Parker extended gratitude to all families who participated in the trial and those who will join future studies.
