    A good score on the A1C test depends on whether you’ve been diagnosed with diabetes. For those who do not have diabetes, a score of less than 5.7% is considered normal, while 5.7% to 6.4% indicates prediabetes and 6.5% or higher means you have diabetes. If you already have diabetes, a score of 7% or lower is desired. You and your doctor can decide what score is best for you. The A1C diabetes test is a way to get an average of how well your blood sugar has been controlled for the past three months.

    Normal A1C level can range from 4.5 to 6 percent. Someone who's had uncontrolled diabetes for a long time can have an A1C level above 9 percent.

    A1C test is used to diagnose diabetes, an A1C level of 6.5 percent or higher on two separate dates indicates diabetes. A result between 5.7 and 6.4 percent is considered prediabetes, which is high risk of developing diabetes.

    For most people who have previously diagnosed diabetes, an A1C level of 7 percent or less is a common treatment target. Higher targets may be chosen in some individuals. If your A1C level is above your target, your doctor may recommend a change in your diabetes treatment plan. Remember, the higher your A1C level, the higher your risk of diabetes complications.

    No one quite agrees on where your A1C score should be, but we all agree on where it shouldn’t be. The scale does not look anything like the BGL numbers you are used to. For all practical purposes, it runs from 5.0 up to 14.0 where most in-house A1C machines max out. Labs can test higher, but at 14.0 your doctor will run screaming for the hills anyway, so it really doesn’t matter. At that level your blood sugar is lethal and your body is slowly dissolving, just as if you had battery acid in your veins and arteries.

    Scores below 6.0 are usually considered to be in the non-diabetic range. At 9.0 we cross the threshold where kidney damage starts. So we can all agree that above 9.0 you are in deep shit and the higher above 9.0 that the number is, the worse off you are because A1C tests are curvilinear. Just like Category 3 hurricanes are much worse than Category 2 storms, or like 7.3 earthquakes are much worse than 7.0s, each increase in your A1C number packs a larger punch than you’d expect.

    The standard A1C goal for most people with diabetes is less than 7%. However, the goal may be individualized or may be different for some people, especially older adults, people with heart disease or those who are prone to frequent low blood glucose. It's a good idea to find out what your A1C goal should be from your healthcare provider and then use that as a benchmark for your A1C results.
