Objective: To assess the management of patients with type 2 diabetes mellitus in the primary care setting, with respect to risk factors associated with coronary heart disease.
Design: Retrospective cross-sectional audit.
Setting: Specialised diabetes assessment clinic in a tertiary referral teaching hospital.
Background: Routine clinical measurements of glycated haemoglobin first became available during the early 1970s and are now accepted as the standard for estimated overall glycaemic exposure and risk of microvascular complications in diabetes.
Objective: This article attempts to answer frequently asked questions concerning A1C, and provide guidance on how to make best use of A1C measurements in clinical practice.
Discussion: Blood glucose gives immediate day-to-day information and A1C usually gives a reliable estimate of the average glycaemic exposure over the past 6-8 weeks.
