A person with diabetes should aim for an eAG less than 154 mg/dl (A1C < 7%) to lower the risk for diabetes complications.The results of an eAG test may not match your average of day-to-day blood sugar tests you have been taking at home on your glucose meter. This is because you are likely to check your sugar levels before meals or when your blood sugar levels are low. But it does not show your blood sugar at other times of the day. So, the average of your results on your meter may be different than your eAG. Your doctor should never tell you what your blood sugar values are based on the eAG because the range of average blood glucose for any individual person is very broad for each A1c level. The value is only an estimate.There are many medical conditions and medicines that change the relationship between A1c and eAG. Do not use eAG to evaluate your diabetes control if you:Have conditions such as kidney disease, sickle cell disease, anemia, or thalassemia Are taking certain medicines, such as dapsone, erythropoietin, or iron Open ReferencesReferencesAmerican Diabetes Association. 6.
