Managing diabetes: HbA1c

Updated On Jan 12, 2022
  • Glycated haemoglobin – occurs when haemoglobin that carries oxygen in your body joins with glucose and becomes ‘glycated’
  • This happens when the body processes sugar 
  • Measuring HbA1c enables an understanding of what your average blood sugar levels have been over a period of 8-12 weeks (duration in which the red blood cells in the human body survive for), therefore can test whether you are normal, pre-diabetic or diabetic
  • HbA1c measures can be taken from blood-prick from your finger or a sample taken from your arm 
  • The amount of glucose to haemoglobin is directly proportional to the total amount of sugar that is in your system at that time 
  • Good control of your HbA1c is known to lower the risk of complications 
  • Therefore, it is recommended to be tested on an annual basis
