What is HbA1c?
HbA1c is shorthand for ‘glycated hemoglobin’. Most of us are familiar with the word hemoglobin, it is the protein in the red blood cells to which glucose sticks, that’s why the name ‘glycated’.
The role of hemoglobin is to carry oxygen across the body. It is also necessary to absorb glucose in the body. The glycated level of hemoglobin can be learned through HbA1c test.
What is the role of HbA1c test in diabetes?
The role of HbA1c test is to give an idea about the average blood sugar levels or percentage of sugar attached to the hemoglobin. This test gives estimates of 2-3 months. This is because the red blood cells in your body live for an average of 2-3 months before getting regenerated.
If your results are uncertain, the doctor will tell you to undergo another test to confirm. The numbers determine whether you are normal, pre-diabetic or have type 2 diabetes.
Below 5.7% - Normal
5.7 to 6.4% - Prediabetes
Above 6.4% - Diabetes
If you are diabetic, this also indicates how you are effectively managing your diabetes. The doctor could use the results to change your medication and diet plan.
If you are correctly managing your diabetes, you are at lower risk of getting vascular complications of heart, kidneys (Diabetic Nephropathy), digestive system, nerves (Diabetic Neuropathy), eyes (Retinopathy) and sexual organs.
