What foods lower blood sugar immediately
This blood test shows your average blood sugar level for the past 2 to 3 months. It works by measuring the percentage of blood sugar attached to the oxygen-carrying protein in red blood cells, called hemoglobin.
An A1C level of 7% or less means that your treatment plan is working and that your blood sugar was consistently within a healthy range.
If your A1C level is higher than 7%, your blood sugar, on average, was above a healthy range. In this case, your health care provider may recommend a change in your diabetes treatment plan.
For some people, especially older adults and those with certain medical conditions, a higher A1C level of 8% or more may be appropriate.
How often you need the A1C test depends on the type of diabetes you have and how well you're managing your blood sugar.
Most people with diabetes receive this test 2 to 4 times a year.
