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.
It can be done at anytime before or after meals.
The best time would be in the morning or evening.
Yes, it is possible.
A1C cannot be lowered overnight
It means that your body is storing glucose in the blood stream and you are probably asymtomatic.However, since you fall under prediabetes you are advised to take your medicines on time and perform regular exercises to keep your blood glucose levels under control.
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
No, they are not the same.
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.
Usually this test can be taken at any time but this test is most preffered in the morning.
Eating before A1C test wont affect the results.
