All UK children could be offered screening for type 1 diabetes using a simple finger-prick blood test, say researchers who have been running a large study.
Currently, many young people go undiagnosed and risk developing a life-threatening complication called diabetic ketoacidosis that needs urgent hospital treatment.
Identifying diabetes earlier could help avoid this and mean treatments to control problematic blood sugar levels can be given sooner.
Some 17,000 children aged three to 13 have already been checked as part of the ELSA, external (Early Surveillance for Autoimmune diabetes) study, funded by diabetes charities.
Imogen, who is 12 and from the West Midlands, is one of those found to have diabetes thanks to the screening.
Her mum Amy says knowing what's coming, rather than being taken by surprise, has made a massive difference to their confidence and peace of mind.
"Imogen took part in the study to further research and help others, but it has helped her too – being forewarned is being forearmed.
"She was always going to develop type 1 diabetes, but through ELSA we've been able to slow down the process and prepare. We know what's coming, but we're not scared."
Imogen is being given ongoing support to prepare her for what is to come.
Amy, who is 44 and has type 1 diabetes herself, is aware of the risks with the disease. She was diagnosed aged 13 after developing diabetic ketoacidosis.
"When I was diagnosed, I had no warning and ended up quite poorly in hospital," she recalls.
