What is HbA1c?
HbA1c (glycated haemoglobin), is when haemoglobin, a protein within red blood cells carries oxygen throughout your body, joins with glucose in the blood, becoming “glycated.”
Measuring HbA1c gives an overall picture of what our average blood sugar levels have been over a period of weeks/months. The blood test in the Sheridan Health Checks will show this over a period of approx. 3 months. For people with diabetes this is especially important as the higher the HbA1c, the greater the risk of developing diabetes-related complications.
How does HbA1c return an accurate average measurement of average blood glucose?
When the body processes sugar, glucose in the bloodstream attached to haemoglobin. The amount of glucose that attaches with this protein is directly proportional to the total amount of sugar that is in your system at that time. Because red blood cells in the human body survive for 8-12 weeks before renewal, HbA1c can reflect average blood glucose levels over that duration, providing a useful, longer-term gauge of blood glucose control.
How does HbA1c differ from a blood glucose level?
HbA1c provides a longer-term trend, similar to an average, of how high blood sugar levels have been over a period of time.Blood glucose level is the concentration of glucose in your blood at a single point in time , i.e. the very moment of the test. This is measured using a fasting plasma glucose test which will only provide an indication of your current glucose levels whereas HbA1c test serves as an overall marker of what your average levels are over a period of 2-3 months.
