Study screened children across Germany, UK, Italy, Denmark, Sweden, Czechia, Portugal, Poland Around 1 in 45 children with a near relative with T1D was found to be in the early stages of the condition, and 1 in 350 children with no relative Protocol developed by German team could be rolled out across Europe and other countries Researchers recommend general population screening at age 2–4 years for T1D, if islet antibody-negative again at age 6–8 years and at age 10–15 years for detecting individuals with early-stage type 1 diabetes. Integrating such screening into other health initiatives should be targeted, this will vary for each country Children who have never been screened could catch up by joining this schedule at the earliest opportunity
