Measuring HbA1c concentration in the blood facilitates the long-term monitoring of blood glucose levels from diabetics.
The glucose of HbA1c may bind itself to proteins – a process called glycation. Red blood cells contain glucose as well, enabling the blood sugar to bind to the blood cell’s haemoglobin – creating haemoglobin A1c, or HbA1c for short.
Even in healthy individuals a part of the haemoglobin is bound. For long-term monitoring and assessment of risks of long-term damage from diabetes, measuring the HbA1c value is crucial.
