The A1c goes by several different names, such aswa Hemoglobin A1C, HbA1C, Hb1C, A1C, glycated hemoglobin, glycohemoglobin and estimated glucose average. As a marker for how much glucose has been present in the blood over time, elevated A1c values are most commonly seen in people with prediabetes and diabetes. However, in these guidelines, A1C is indicated as a diagnostic tool alternative but not superior to blood glucose, leaving to the health care professional the decision about what test to use in an individual. Can you please let me know how the average values were this high even though fasting and PP was normal during this period. It comes from high postprandial glucose values, high values after meals.

The test for hemoglobin A1c depends on the chemical (electrical) charge on the molecule of HbA1c, which differs from the charges on the other components of hemoglobin.
