Usually this test can be taken at any time but this test is most preffered in the morning.

No, A1C blood test can be given even without fasting.
It is possible to have high A1C levels without diabetes in rare cases. Iron, folate etc can also increase HBA1C levels.
The best time would be in the morning or evening.
