1 If a person is diagnosed with diabetes, then the physician may recommend regular HbA1c tests in the future. 2  Depending on the type of diabetes, the patient may need to undergo the HbA1c normal range test after every 3 to 6 months.ed blood cells typically live for approximately 120 days in the bloodstream. This allows an HbA1c range test to determine the levels of sugar occurring in the body for over the past 3 months. As compared to regular monitoring of glucose carried out at home, an HbA1c range test is more reliable and relatively better.
