When Should HbA1c (Hemoglobin A1c) Levels Be Tested?
In addition to random fasting blood glucose levels, HbA1c levels are routinely measured (tested) in the monitoring of people with type 1 and type 2 diabetes. HbA1c levels depend on the blood glucose concentration. That is, the higher the glucose concentration in blood, the higher 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.

What Are the Limitations to Measuring HbA1c (Hemoglobin A1c)?
Since HbA1c is not influenced by daily fluctuations in blood glucose concentration, it cannot be used to monitor day-to-day blood glucose concentrations and is inappropriate to be used for adjusting insulin doses; nor can it detect the day-to-day presence or absence of hyperglycemia or hypoglycemia. HbA1c may be increased falsely in certain medical conditions. These conditions include
