HbA1c is a form haemoglobin which has been non-enzymatically glycated. The amount of HbA1c present reflects blood glucose levels during the life of the red cells (normally 120 days). Production of rapid quantitative HbA1c results may be used in monitoring glycaemic control in known diabetics and should not be used for diagnosis since there is a significant overlap between diabetic and non-diabetic subjects.
Capillary whole blood (e.g. finger-prick) or venous whole blood with EDTA, heparin, citrate or sodium fluoride anti-coagulant.

Finger-prick samples must be analysed immediately.
Anticoagulated venous samples can be stored in the fridge for up to 10 days before analysis, and can be sampled cold
Do not excessively squeeze the patients finger which dilutes the sample with tissue fluid
