How often should A1c be checked in diabetes management?

• A. 3-6 months
• B. 1-2 months
• C. 6-12 months
• D. Annually

Answer: (A)

A1c shows the average blood glucose over about the last 3 months, so the test interval is tied to how stable a person’s control is and whether treatment has recently changed. When therapy is being adjusted or control isn’t at goal, checking about every 3 months helps gauge response and guide further changes. Once a patient has been at goal on stable therapy for a while, the interval can be extended to about every 6 months. Testing more frequently than every 3 months doesn’t add much new information because A1c reflects longer-term control, while waiting longer than 6 months risks missing trends in glucose management. So the general and most appropriate range is every 3 to 6 months.
