HbA1c (Glycated hemoglobin or hemoglobin A1c)



What Does it do?

In addition to random monitoring daily blood glucose levels, HbA1c levels are routinely measured in the monitoring of people with diabetes. HbA1c levels depend on the blood glucose concentration. That is, the higher the glucose concentration in blood, the higher is the level of HbA1c. Levels of HbA1c are not influenced by daily fluctuations in the blood glucose concentration but reflect the average glucose levels over the prior six to eight weeks. Therefore, HbA1c is a useful indicator of how well the blood glucose level has been controlled in the recent past (over two to three months) and may be used to monitor the effects of diet, exercise, and drug therapy on blood glucose in people with diabetes.

How To prepare for the test?

This test can be done at any time of the day at a pathology lab, and no fasting is required prior to it. In some clinics, the test can also be done on the spot.

Normal Range:

A non-diabetic should have an A1c result between 4% and 6%.

People with diabetes should aim for 7% or less.

Action is suggested if your percentages are over 7-8%.
