what is a hemoglobin a1c
The A1C test is a blood test used to measure the average level of glucose in the blood over the last two to three months, and is used as a means of checking how well blood sugar levels are being controlled for a person with diabetes. Prediabetes, a risk factor for diabetes, is signaled by levels between 5.7-6.4%. 2  A result below 5.7% indicates a healthy blood sugar level. 3  The typical target for people with diabetes is to get their A1C below 7%, but there are different targets for different individuals and stages of the disease.
