To monitor a person’s diabetes and to help treatment decisions.
It can also be used to diagnose type 2 diabetes.
When first diagnosed with diabetes and then at least twice a year
A blood sample taken from a vein in the arm.
Some of the glucose in your blood binds to hemoglobin (the protein that carries oxygen in your red blood cells).
This combination of glucose and hemoglobin is called hemoglobin A1c (HbA1c).
The amount of HbA1c formed is directly related to the average concentration of glucose in your bloodstream. Red blood cells live for 2–3 months, and because of this, the amount of HbA1c in your blood reflects the average level of glucose in your blood during the last 2-3 months. If your diabetes is not well controlled, your blood glucose levels will be high, causing higher HbA1c levels.
How is the sample collected for testing?
Your blood may be taken from a vein in your arm or, in some cases, a drop of blood from a finger-prick may be used.
Is any test preparation needed to ensure the quality of the sample?
No test preparation is needed.
