An assembly committee says early identification is key to tackling type 1 diabetes in children and young people.
An inquiry was launched by the Petitions Committee after receiving a petition from the family of Peter Baldwin calling on the Welsh Government to introduce routine screening for diabetes in children and young people.
13-year-old Peter died in 2015. He was initially diagnosed with a chest infection by his GP, but became ill the following day and was rushed to hospital. The paramedic who attended carried out a finger prick test and diagnosed type 1 on the spot. Unfortunately Peter was already too ill and died soon after.
Peter's family have campaigned for changes ever since.
The committee was told that type 1 diabetes was a rare condition, and that some GPs may only see one new case during their career.
There are approximately 1,400 children with diabetes in Wales, with 96 per cent of them having type 1 diabetes.
The committee is recommending that questions about the four 'T' symptoms should be routinely asked when unwell children and young people see a GP or other health professional - Toilet, Thirsty, Tired and Thinner.
The report and its recommendations will now be considered by the Welsh Government with a debate to be held during Plenary in the autumn.
