A1C test

The A1C test is a laboratory test that measures your average blood glucose (sugar) level over three to four months. The value is reported as a percentage.

Your A1C is the best way to tell how your treatment plan is working overall. The target goal is 7 percent or less. When at least half of your self-tested blood glucose levels are within the target range, your A1C will usually be in target, too. For example, if your average blood glucose level is 150, your A1C will be about seven percent.

Ideally, you should have an A1C test every three to four months.

If your A1C is:	your average blood glucose level is:
4 percent	60
5 percent	90
6 percent	120
7 percent	150
8 percent	180
9 percent	210
10 percent	240
11 percent	270
12 percent	300
13 percent	330
