A1C ( HbA1C, Hemoglobin A1C test)

The A1C is a type 2 diabetes and prediabetes blood test. It measures your overall three-month average blood glucose level. The A1C can be used alone or in conjunction with other diabetes tests to identify whether or not someone has diabetes.


The A1C is a test that assesses how well you manage your diabetes. This test differs from typical blood sugar tests performed by diabetics on a regular basis.

A1C testing is a test that measures blood sugar levels over the previous three months. The percentage at which your A1C result is expressed indicates how much your blood sugar levels have increased:

A level of 5.7 percent or higher is considered high, while levels below 5.7 percent are considered normal.

In prediabetes, the proportion ranges from 5.7 to 6.4 percent. Having prediabetes is associated with developing type 2 diabetes. Individuals who have prediabetes may need to retake their blood sugar levels on a yearly basis or twice a year.

Type 2 diabetes has a prevalence of 6.6 percent or more.

If you have diabetes, you should get the A1C test at least twice a year. The desired A1C level for many people with diabetes is below 7. For you, it may be different. Find out what your goal is. You may have to make adjustments to your diabetes therapy if your A1C level is excessively high.
