Hemoglobin a1c, also known as hba1c, is widely touted as the "diabetic truth detector". measuring the percentage of red blood cells that have been "glycated," or permanently chemically joined to sugar, hba1c is a good indicator of how well diabetics have kept their blood glucose levels under control over the preceding 90 to 120 days, offering a more long-term picture that can follow red blood. If your finger-stick blood tests give an average blood sugar that is much higher or lower than your a1c test, ask your doctor if the a1c is the right test for you. an alternative test to the a1c is a fructosamine test. unfortunately, the fructosamine test and the a1c are not interchangeable because they are measuring different things.. Key messages. the chronic hyperglycemia of diabetes is associated with significant long-term microvascular and cardiovascular complications. a fasting plasma glucose of ≥7.0 mmol/l, a 2-hour plasma glucose value in a 75 g oral glucose tolerance test of ≥11.1 mmol/l or a glycated hemoglobin (a1c) of ≥6.5% can predict the development of retinopathy..
Glycated hemoglobin test (a1c):. average blood sugar levels in the body over the last 2–3 months by measuring the blood sugar attached to the blood hemoglobin. normal: = /<5.7% prediabetes: 5.7%–6.4% • type 2 diabetes: = />6.5% fasting blood glucose and impaired fasting glucose:.

A1c differences in ethnic populations and children. in the adag study, there were no significant differences among racial and ethnic groups in the regression lines between a1c and mean glucose, although the study was underpowered to detect a difference and there was a trend toward a difference between the african and african american and the non-hispanic white cohorts, with higher a1c values.
The a1c is a blood test that gives us an estimated average of what your blood sugar has been over the past 2-3 months. the a1c goes by several different names, such as hemoglobin a1c, hba1c, hb1c, a1c, glycated hemoglobin, glycohemoglobin and estimated glucose average..

Glycemic control is essential to delay or prevent the onset of diabetic kidney disease. there are a number of glucose-lowering medications available but only a fraction of them can be used safely in chronic kidney disease and many of them need an adjustment in dosing. the ideal target hemoglobin a1c is approximately 7 % but this target is adjusted based on the needs of the patient..
