What is the difference between HBA1C and blood sugar levels?
The difference is A1C is the mean average for 3 months of control of blood sugar levels. Whereas fasting blood sugar levels are of the same day.

Both are accurate. A1C gives the control for 3 months whereas fasting glucose will give the results for that particular day.
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.
A1C cannot be lowered overnight
