HbA1c Blood Test

HbA1c Blood Test monitors the average blood glucose levels in someone with diabetes and to help treatment decisions. It can also be used to make a diagnosis of type 2 diabetes and to identify prediabetes.

Some of the glucose in your blood binds to haemoglobin (the protein that carries oxygen in your red blood cells). This combination of glucose and haemoglobin is called haemoglobin 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.

HbA1c Blood Test

A hemoglobin A1c test measures how much a person’s glucose levels have been in and out of the healthy (or target) range during the last 2-3 months. Glucose is a type of sugar used by the body for energy. Hemoglobin is the protein inside red blood cells that carries oxygen. If too much glucose builds up in blood, it binds to hemoglobin. High hemoglobin A1c levels can happen when someone’s blood sugars have been higher than their healthy range.
The A1C test measures the amount of glucose in your blood that has become attached to hemoglobin. Hemoglobin is a protein that allows red blood cells to carry oxygen from your lungs to the rest of your body. When glucose enters your blood, it binds with the hemoglobin in your red blood cells. The more glucose in your blood, and the longer it stays elevated, the more it will attach to the hemoglobin.

The A1C test result is reported as a percentage. The higher the percentage, the higher your blood glucose levels. A normal A1C level is below 5.7 percent.

The form of hemoglobin in your blood depends on genes you inherit from your parents. Many different forms of hemoglobin exist. The most common form is hemoglobin A, also called normal adult hemoglobin. Other, less common forms of hemoglobin are called hemoglobin variants.

Hemoglobin variants can affect the results of some A1C tests. These variants are more common in some parts of the world, such as Africa, South and Southeast Asia, and the Mediterranean. If your ancestors came from these regions, you may have a form of hemoglobin in your blood that could affect your A1C test results.

Why have a HbA1c Blood Test

The Department of Health & Social Care recommends that everyone with diabetes has HbA1c measured at least twice a year. HbA1c may be measured more frequently in those who have just been diagnosed with diabetes, in those whose blood glucose remains too high, or when a treatment plan changes. The test can also be used to diagnose type 2 diabetes. Please speak to your healthcare professional as there are certain groups of patients in which HbA1c cannot be used to diagnosis diabetes.
