There is no single best time. When the A1C is above 8.5% the fasting glucose plays a greater role in overall diabetic control. As the A1C drops below 8.5% however the 2 hour postprandial (after meal) glucose plays a greater role than the fasting glucose. Therefore both the fasting and the 2 hour postprandial readings are important. The glycated (the more common terminology 'glycosylated' is biochemically incorrect according to the International Journal of Biomedical Nomenclature) hemoglobin A1C measures the 90 day mean (average) glucose. An A1C of 8.5% approximates (the relationship between the A1C and glucose is nonlinear) a 90 day mean glucose of 199 mg/dL or 11.0 mmol/L. The goal for a diabetic is an A1C of 6.5% which approximates a 90 day mean glucose of 141 mg/dL or 7.8 mmol/L. The ideal fasting glucose is less than 100 mg/dL or 5.6 mmol/L and the ideal 2 hour postprandial glucose is less than 140 mg/dL or 7.8 mmol/L. Unfortunately driving glucose down to such an ideal most often produces unacceptable episodes of hypoglycemia. There is also limited data to suggest that driving the A1C down to the level of a non-diabetic - less than 6.0% which approximates a 90 day mean glucose of 126 mg/dL or 7.0 mmol/L - may be associated with adverse health outcomes. There is a medical trial being undertaken at this time to answer this question but results are not anticipated for 3 to 5 years at the earliest. If I may be of further assistance please let me know. I wish you the very best of health and happiness and in all things may God bless. JR

Bad situation here. What is the SINGLE best time of day to test glucose? Type 2 diabetes.?

I believe for the single best time would be 2 hours after you eat. But if you are not going to do anything about the results, then why test?
Most type 2 diabetic test too much. Lured in by the drug companies and Ol' Wilford Brimley.Good Luck to you
