Website maintenance is planned from 8:00 a.m. CDT Saturday, July 27, through 9:00 p.m. CDT Sunday, July 28. Brief disruptions may occur during this time.
The lifespan of an A1C is approximately 90 to 120 days, and the full effects of a patient’s change in behavior, diet, or newly adjusted medications will not be fully appreciated until all previous A1C in circulation are replaced (~90 days). Therefore, testing at time intervals earlier than three months may not allow enough time to pass to reach the expected target by the clinician. Testing at six-month intervals may be considered when glycemic targets are consistently achieved.
