Glycated Haemoglobin Test

Glycated Haemoglobin (HbA1C) is a measure of blood glucose control over the medium term of approximately 3 months (the life-span of an average red blood cell). Increased levels of blood sugar over a sustained period of time cause compounds related to sugar to be attached to the haemoglobin protein in red blood cells.

How the Test is Performed

Glycated Haemoglobin (HbA1C) is a blood test. A few millilitres of blood from a vein are required.

Medical Conditions and Symptoms

Glycated Haemoglobin (HbA1C) is a measure of blood glucose control in patients with diabetes. This test gives a relatively good idea of how strict blood sugar control has been over the three months prior to the test.

Test Results Explained

A high level of HbA1C suggests poor blood-sugar control over the previous weeks. A low HbA1C is a “pat on the back” for a diabetic patient because it reflects strict control over the previous weeks.
