Which is the best time to test HbA1c?
The best time would be in the morning or evening.

Both are accurate. A1C gives the control for 3 months whereas fasting glucose will give the results for that particular day.
Fasting blood sugar (in the morning, before eating) should be Less than 100 mg/dL. 1-2 hours after a meal should be Less than 140 mg/dL. And 2-3 hours after eating should be Less than 100 mg/dL
Eating before A1C test wont affect the results.
It is possible to have high A1C levels without diabetes in rare cases. Iron, folate etc can also increase HBA1C levels.
