Hemoglobin a1c (HgBA1c, normally abbreviated HbA1c or simply A1c) is a test done to monitor diabetes, specifically how well diabetes is under control over a period of months, according to Medline Plus. Normal levels vary based on several factors.
Identification
Normal HbA1c varies based on whether or not a person has diabetes. A person who does not have diabetes will have a normal HbA1c of 6 percent or lower, while a person with diabetes should have an HbA1c of 7 percent or lower, according to Medline Plus.
Features
Normal ranges for HbA1c are only averages, and Medline Plus reports that each individual person has his own normal HbA1c.
Lab Variances
Numbers from an HbA1c test will vary between laboratories, according to Medline Plus. A doctor can help a patient understand these differences.
Recommendations
It is generally indication of well controlled diabetes if a diabetic can keep her HbA1c near 6 percent without having low blood sugar, according to Lab Tests Online.
Considerations
Complications of long-term high HbA1c include eye and heart disease, damage to the kidneys and nerves as well as stroke, according to Medline Plus.
