Screening UK Biobank blood samples identifies thousands of undiagnosed cases of type 2 diabetes

A study of approximately 200,000 blood samples from the UK Biobank has identified more than 2,000 undiagnosed cases of type 2 diabetes. The study, presented at this year's Annual Meeting of the European Association for the Study of Diabetes (EASD), also shows that, because UK Biobank data is not reported back to participants, patients found to have undiagnosed diabetes waited on average more than two years for a clinical diagnosis, and around a quarter remained undiagnosed five years later.
