A1C level testing
A1C level testing
Glycated hemoglobin (A1C) test. This blood test, which doesn't require fasting, indicates your average blood sugar level for the past two to three months. It measures the percentage of blood sugar attached to hemoglobin, the oxygen-carrying protein in red blood cells.
The higher your blood sugar levels, the more hemoglobin you'll have with sugar attached. An A1C level of 6.5 percent or higher on two separate tests indicates that you have diabetes. An A1C between 5.7 and 6.4 percent indicates prediabetes. Below 5.7 is considered normal.

What are normal blood sugar levels?
The blood sugar level before and after eating.
- Fasting plasma glucose test. The doctor tests your blood sugar levels after fasting for 8 hours and it’s higher than 126 mg/dL.
- Oral glucose tolerance test. After fasting for 8 hours, you get a special sugary drink. Two hours later your sugar level is higher than 200.
- Random check. The doctor tests your blood sugar and it’s higher than 200, plus you’re peeing more, always thirsty, and you’ve gained or lost a significant amount of weight. He’ll then do a fasting sugar level test or an oral glucose tolerance test to confirm the diagnosis.

What Are Normal Blood Sugar Levels?
They're less than 100 mg/dL after not eating (fasting) for at least 8 hours. And they're less than 140 mg/dL 2 hours after eating.
During the day, levels tend to be at their lowest just before meals. For most people without diabetes, blood sugar levels before meals hover around 70 to 80 mg/dL. For some people, 60 is normal; for others, 90.
What's a low sugar level? It varies widely, too. Many people's glucose won't ever fall below 60, even with prolonged fasting. When you diet or fast, the liver keeps your levels normal by turning fat and muscle into sugar. A few people's levels may fall somewhat lower.
