The Clinical Significance of HbA1c (Glycated Hemoglobin) Test for People with Diabetes

Red blood cells floating around the body occasionally bump into glucose, which sticks to hemoglobin in these cells. Generally, only a small amount of hemoglobin gets coated with glucose. The HbA1c level is usually about 4%~6% in healthy people. A diabetic has high level blood glucose, so his HbA1c level will be high. Specifically, the clinical significance of HbA1c test for diabetics can be listed as follows.

Firstly, HbA1c testing is recommended for both checking blood sugar control in people who may be pre-diabetic and monitoring blood sugar control in Diabetes, because the HbA1c test shows the average level of blood sugar for the past 3 months. The goal for diabetics is a level of 7% or less of HbA1c. If your HbA1c level is higher than normal range, it means that your blood sugar levels have been too high over the previous 3 month and the healthcare provider usually needs to make adjustments your Diabetes treatment plan.

Secondly, the HbA1c test can also help your doctors see how big your risk is of developing diabetic chronic complications. In general, the high your HbA1c, the higher the risk that you will develop problems such as eye disease, heart disease, kidney disease, nerve damage, and stroke, etc.

Thirdly, the HbA1c test can be used to diagnose Diabetes. The 2010 American Diabetes Association Standards of Medical Care in Diabetes added the HbA1c ≥ 48mmol/mol (≥6.5%) as another criterion for the diagnosis of diabetes.

Finally, the HbA1c test acts as a differential diagnosis of stress hyperglycemia. The blood sugar caused by simple stress will not rise, but it rises in diabetics.
