HbA1c-Normal values: refers to glycated hemoglobin, a measure of hemoglobin (oxygen carrying element of the Red Blood Cells) is paired with glucose as it circulates through the body becoming glycated.
HbA1c is a measurement, over an average of 3 months. This determines average blood sugar over a period of time.
�Because red blood cells in the human body survive for 8-12 weeks before renewal, measuring glycated hemoglobin (or HbA1c) can be used to reflect average blood glucose levels over that duration, providing a useful longer-term gauge of blood glucose control� (Diabetes.co.uk)
The HbA1c testing requires no prior preparation and is based on a blood draw from a venous source.
