HbA1c, also known as glycated hemoglobin, is produced when glucose in the blood sticks to hemoglobin, a protein within red blood cells required for the transportation of oxygen. As a rule, the more glucose in the blood, the more HbA1c is produced.

HbA1c and Diabetes
People with diabetes have a consistently higher-than-normal level of sugar (glucose) in their blood.

Because high blood sugar over a prolonged period can be very dangerous to health, diabetics must monitor their blood glucose levels carefully to ensure they do not get too high (or too low). This is why measuring levels of HbA1c, which is an indicator of average blood glucose levels, is a useful test to assess whether diabetes is being managed effectively or not. It can also be used as a diagnostic tool for this disorder and to highlight people at risk of developing it (called pre-diabetics).

As red blood cells have a lifespan of approximately 3 months before they are replaced, measuring HbA1c can reflect how high blood sugar levels have been, on average, over the previous 3 months.

How Does the HbA1c Test Work?
The HbA1c test is used to measure the amount of glycosylated hemoglobin in the blood.

It is recommended that people diagnosed with diabetes have an HbA1c reading every 3 to 6 months, and more frequently for those planning to start a family, having problems controlling their blood sugar, or who have had a recent change to their treatment plan.
