The term HbA1c refers to glycated haemoglobin. By measuring glycated haemoglobin (HbA1c), clinicians are able to get an overall picture of what our average blood sugar levels have been over a period of weeks/months.
For people with diabetes this is important as the higher the HbA1c, the greater the risk of developing diabetes-related complications.
A blood glucose test measures the amount of glucose in your blood. Glucose, a type of simple sugar, is your body’s main source of energy. Your body converts the carbohydrates you eat into glucose.
Glucose testing is primarily done to check for type 1 diabetes, type 2 diabetes, and gestational diabetes. Diabetes is a condition that causes your blood glucose level to rise.
The amount of sugar in your blood is usually controlled by a hormone called insulin. However, if you have diabetes, your body either doesn’t make enough insulin or the insulin produced doesn’t work properly. This causes sugar to build up in your blood. Increased levels of blood sugar can lead to severe organ damage if left untreated.
In some cases, blood glucose testing may also be used to test for hypoglycemia. This condition occurs when the levels of glucose in your blood are too low.
