Type 1 Diabetes: Infant Testing

Seamus Logan Excerpts

Monday 9th March 2026 Westminster Hall

[Seamus Logan (Aberdeenshire North and Moray East) (SNP)]

It is a pleasure to serve under your chairship, Sir Alec. I thank the hon. Member for North Ayrshire and Arran (Irene Campbell) for opening this important debate, and I pay tribute to the members of the public present, who no doubt represent thousands of people online tonight.

The Lyla’s law campaign is a powerful reminder of the devastating consequences of missed or delayed diagnosis for type 1 diabetes in children and young people. It calls for improved education and guaranteed routine testing for children showing early symptoms before they reach diabetic ketoacidosis, which is a life-threatening condition that requires emergency hospital care. Many families and parents learn about their children’s condition only once they have reached this potentially fatal stage. Not only is that traumatic and dangerous, putting a child’s life at risk, but it creates avoidable costs and puts strain on emergency healthcare services. Families should not have to wait for those serious complications to occur for a diagnosis to be made.

Despite this, the UK Government claim that there is still “insufficient evidence” to support routine mandatory testing for type 1 diabetes in babies, toddlers and young children. That is why the petition is so important. It calls for existing NHS guidance, which recommends the immediate testing of children and young people showing symptoms of type 1 diabetes—the fours Ts, which have been mentioned—to be formally legislated for. Current guidance alone is clearly not enough, and a standardised approach for all GPs and doctors is urgently needed.

A member of the Insulin Pump Awareness Group in Scotland recently wrote to me mentioning that they often wonder whether their own diagnosis 29 years ago would have been picked up had they not been made aware of the four Ts symptoms through family.

My West Dunbartonshire constituent Janice shared with me the very personal story of her daughter, who three years ago became so unwell that she was admitted to hospital. She was desperately ill, but she survived. The signs had been there, but they were missed, with the diagnosis coming at the very last moment, in an emergency setting. Will the hon. Member join me in commending the work of Diabetes Scotland and its efforts to improve testing, screening and early diagnosis in Scotland?

[Seamus Logan]

I completely agree with the hon. Member and endorse his suggestion.

This topic is personally important to me, not only because so many family members have been diagnosed with type 1 diabetes but—as the hon. Member for Edinburgh North and Leith (Tracy Gilbert) referred to—because of the premature death in 2022 of my nephew Nick Logan from complications arising from his original diagnosis at the age of 16.

Italy made history in 2023 by becoming the first country to introduce nationwide screening for the early detection of type 1 diabetes in children. In 2021, Scotland also led the way by being the first country to offer C-peptide blood tests to everyone with diabetes to address misdiagnosis. Although that may not be the same as a routine screening programme for type 1 diabetes, it demonstrates how routine testing can be implemented.

Childhood type 1 diabetes rates in the UK are among the highest in the world, ranking fifth globally for children aged 14 and under, according to the International Diabetes Federation. In conclusion, it is essential that the UK Government take a more targeted and strategic approach to improving the care and diagnosis of children and young people showing type 1 diabetes symptoms. That starts with the implementation of routine testing—
