  • An HbA1c threshold of ≥42 mmol/mol has been proposed to diagnose prediabetes. The sensitivity, specificity and positive predictive value of the proposed threshold for detection of individuals with prediabetes was examined in a study of 573 randomly selected individuals from Vara and Skövde. In addition, the utility of the FINDRISC questionnaire and of a fasting glucose test in combination with three short questions concerning BMI, heredity for type 2 diabetes and known hypertension was examined. Results from an oral glucose tolerance test were used as reference. The sensitivity of HbA1c and FINDRISC to detect individuals with IGT was 16 and 26 per cent respectively. Questions regarding BMI, heredity and hypertension together with a fasting glucose test yielded a sensitivity of 50%, but a lower specificity and positive predictive value. We conclude that HbA1c inefficiently detected individuals with impaired glucose tolerance and that oral glucose tolerance tests can still preferably be recommended.
