A1C of 7%: Is It a Good A1C?
An A1C under 7% (53 mmol/mol) is the goal the ADA gives for many nonpregnant adults with diabetes. It matches an estimated average glucose of about 154 mg/dL. Your own goal may be different.
Where the 7% goal comes from
The American Diabetes Association (ADA) Standards of Care say an A1C goal of under 7% is appropriate for many nonpregnant adults, as long as it can be reached without significant low blood sugar. It is a common target, not a rule for everyone. Use the A1C calculator to see what 7% means as an average glucose.
Who may have a different goal
- A lower goal. The ADA says goals such as under 6.5% (48 mmol/mol) may suit people in good health and function when the treatment risks are low.
- A less strict goal. The ADA says looser goals may suit people with significant cognitive or functional limits, frailty, or severe other conditions, or where the harms of treatment outweigh the benefits.
- Pregnancy and children. These have their own guidance. Your care team sets the targets.
A1C is one measure. Time in range is another
Two people with the same A1C can have very different days. If you use a continuous glucose monitor (CGM), the ADA also gives a time-in-range goal of more than 70% for many nonpregnant adults. A1C averages out highs and lows. Time in range shows how many hours are spent between the targets set with your care team. Your clinician can tell you which measures matter most for you.
How often to check
The ADA suggests an A1C test at least twice a year, and more often, for example about every three months, if goals are not being met or if treatment has changed. Because A1C reflects about two to three months, a change you make today shows up in the next result, not tomorrow.
If your A1C is above 7%
A higher number is information, not a failure. There are many reasons it can be above a goal, and many options your care team can discuss. Read what the official sources say about lowering A1C, and bring questions to your next visit. Please do not change medicine on your own.
Frequently asked questions
Is an A1C of 7 good?
For many nonpregnant adults with diabetes, the ADA says a goal under 7% is appropriate. Whether 7 is right for you depends on your health, treatment and risk of low blood sugar. Ask your care team.
What is an A1C of 7 in mg/dL?
About 154 mg/dL (8.6 mmol/L) as an estimated average over two to three months.
When is a lower or higher goal used?
The ADA says lower goals, such as under 6.5%, may suit people in good health with low treatment risks, and less strict goals may suit people with significant cognitive or functional limits, frailty or severe other conditions.
How often should A1C be checked?
The ADA suggests at least twice a year, and more often, for example every three months, when goals are not met or treatment has changed.
