Screening for diabetes mellitus using HbA1c
Welsh Endocrinology and Diabetes Society
Primary care is the usual point of diagnosis and care for people with diabetes. Glycated haemoglobin (HbA1c) is an effective gauge of blood glucose control and a predictor for the risk of a patient having or developing diabetes. Knowing when HbA1c is a valid test to use, when blood glucose testing is required, and which thresholds require treatment is vital to running an efficient and effective diabetes service.
This new Guidelines summary covers when HbA1c should not be used as a sole test to diagnose diabetes, and includes an algorithm on diagnosis of diabetes and the HbA1c thresholds for intervention.
