How often should an HbA1c test be conducted?According to the American Diabetes Association's current clinical practice recommendation, everyone with diabetes needs to be tested two to four times a year - depending on how well their diabetes is under control.

Does the HbA1c test diagnose diabetes?No, the HbA1c test is not used to diagnose diabetes. It is a tool used to help manage the disease. Even if there is an occasional high or low blood sugar reading, a good HbA1c result can show that overall you are doing a good job of controlling your diabetes.
For diagnosig the disease, health care professionals will do a blood sugar check during an office visit to look for high elevations of glucose. If the blood sugar check is normal, but the physician still suspects a problem, he or she may require a fasting glucose or an oral glucose tolerance test.

Could a patient do a fructosamine test in place of daily blood sugars or in place of an HbA1c test?Fructosamine tests indicate the level of blood glucose control over the past two to three weeks. It can indicate changes in glucose levels more rapidly then an HbA1c test can. However, people might be tempted to shoot for too low of a fructosamine level, and this might result in dangerous low blood sugars since it is a shorter interval than the Hemoglobin A1c. Therefore, it is not recommended to replace a Hemoglobin A1c, but to complement it.

What is the advantage of a hemoglobin A1c test over daily blood sugar monitoring?The important advantage of HbA1c testing is that the sample can be drawn at any time, because it is not affected by short-term changes like food intake, exercise, stress, hypoglycemic agents, and patient cooperation. By contrast, daily blood sugar monitoring can be affected by all of the above.

What condition(s) can cause, or be associated with, decresed Hemoglobin A1c levels?Conditions that can cause decreased levels include, but are not limited to:
Hemolytic Anemia (premature destruction of red blood cells)
Chronic blood loss
Chronic renal failure

What condition(s) can cause, or be associated with, increased Hemoglobin A1c levels?Conditions that can cause increased levels include, but are not limited to:
Newly diagnosed diabetes
Poorly controlled diabetes
Nondiabetic hyperglycemia
Removal of the spleen
Pregnancy

What is the target goal of therapy in HbA1c (hemoglobin A1c testing)?The American Diabetes Association recommends that the goal of therapy be an HbA1c level between 5-7%, however, each patient's history, response to treatment and severtiy of disease will allow the physician to set individual patient goals. The ADA further recommends that physicians should re-evaluate the treatment regimen in patients with HbA1c values consistently greater than 8%.

Why don't my blood sugar logs match my hemoglobin A1c?There are several reasons why this could occur. The hemoglobin A1c is not just an average of all the highs and lows over the last 3-4 months. It is a "weighted average." This means results are more affected by recent glucose levels than by older ones. Older glucose levels account for only about 10% of the result, because most of the red blood cells that were around have died off. By contrast, the more recent glucose levels account for about one half of the result. That is why it is called a "weighted average."
There are, also, large gaps of time in between glucose measuring (for example, while you sleep), so it is important to look at the different intervals. It is always best to consult with your primary health care professional to review all of your results.
