Use of point‐of‐care HbA_1c measurement to estimate the level of undiagnosed diabetes mellitus among 67‐year‐old participants in a cardiovascular screening programme in the municipality of Viborg, Denmark

Abstract

The prevalence of unidentified diabetes was 3.3% based on a single HbA measurement. Furthermore, 16.7% of those reporting not to have diabetes had an HbA level of 41-48 mmol/mol (5.9-6.5%), representing a subgroup with an increased risk of developing diabetes. Among those with self-reported diabetes, 30.1% had an HbA level ≥58 mmol/mol (7.5%) and 6.3% had a level >74 mmol/mol (8.9%).
