The A1C blood or HbA1C test is used to diagnose Type 1 or Type 2 Diabetes and monitor the management of those currently diagnosed. These values are often reported in percentages. The results of this test calculates the average of your blood sugar levels for the past 3 months.
Estimated average glucose (eAG) is also another term for A1C and can be found on a glucagon meter used to test blood sugars at home.
This table shows the comparison in A1C and eAG values.
6.5% is considered prediabetic, 5.7% is considered normal and less than 5.7% is considered low with no trace of diabetes.
