The hemoglobin A1c test -- also called HbA1c, glycated hemoglobin test, or glycohemoglobin -- is an important blood test used to determine how well your diabetes is being controlled. For people without diabetes, the normal range for the hemoglobin A1c test is between 4% and 6%. People with diabetes should have this test every three months to determine whether their blood sugars have reached the target level of control. Patients with diseases affecting hemoglobin such as anemia may get abnormal results with this test. The a1c test and diabetes – national institutes of health, The a1c test and diabetes.

Background: The American Diabetes Association now recommends glycated hemoglobin A1C (A1C) screening for diagnosis of diabetes (DM)1.


Methods: We surveyed a group of HIV infected patients attending the Bellevue Virology Clinic and collect-ed A1C and FBG levels as well as additional clinical data. Results: From October 2009 through April 2010, 490 patients had an A1C test and 395 met inclusion crite-ria. Conclusions: Among HIV-infected, non-diabetic patients, A1C screening using ADA criteria is insensitive, though highly specific for new cases of DM.
Because studies have repeatedly shown that out-of-control diabetes results in complications from the disease, the goal for people with diabetes is an hemoglobin A1c less than 7%.
Other abnormalities that can affect the results of the hemoglobin A1c include supplements such as vitamins C and E and high cholesterol levels.
It has been reported that A1C levels underestimate hyperglyce-mia in HIV infected persons2,3,4. The Receiver Operating Characteristic (ROC) curve was used to assess screening test performance.


If your glucose levels have been high over recent weeks, your hemoglobin A1c test will be higher. Both increased mean corpuscular volume (MCV) and Abacavir use have been independently associated with A1C-glycemia discordance. The effect of treatment regimen on the relationship be-tween A1C and FBG was assessed by multiple linear regressions. We examined the performance of A1C screening for incident diabetes in a group of HIV infected non-diabetics and examined the effect of an-tiretroviral regimen on the association of A1C and fasting blood glucose (FBG). Patients were included unless they had known DM, were pregnant, on corticosteroids, recently admitted or transfused, or had underlying hemo-globinopathy.

    Ensure the right amount of insulin.

    You may need to test multiple times a day people with diabetes and can person.
