It is a convenient way to obtain an integrated assessment of antecedent glycaemia over an extended period under real life conditions and is used as a standard for assessing overall blood glucose control. The target is to achieve an HbA1c within 1% of the upper limit of normal or achieve control as near to this target as possible without producing unacceptable hypoglycaemia as recommended from the Principles of Care and Guidelines for the Clinical Management of Diabetes Mellitus. If HbA1c is 2% above the upper limit of normal, explore reasons for unsatisfactory control such as diet, intercurrent illness, appropriateness of medication, concurrent medication, stress, and exercise and review management:
