HbA1c and Estimated Average Glucose

Hello Awesomites!

Sounds new. Wait till the end!

Do You know what is HBA1c?

HbA1c is produced by the condensation of Glucose with N-terminal valine of each beta chain of HbA.

Diagnostic importance
The rate of synthesis of HBA1c is proportional to exposure of RBC to glucose. Concentration of HBA1c is indication of blood glucose concentration.
It reflect mean blood Glucose level over 2-3 months prior to its measurement.If HbA1c is <7% then diabetes is in good control. To get an accurate result the concentration should be monitored for several months.

Estimated average glucose (eAG) :- It is new term in diabetic management.It helps to interpret HbA1c levels into average glucose concentration.
eAG(mg/dl) =(28.7×HbA1c) - 46.7

The A1c doesn’t replace self blood-glucose monitoring. Because the A1c is an average of all your blood sugars, it does not tell you your blood sugar patterns. If someone has certain type of hemoglobin mutations (variation in the hemoglobin structure) (HbA1c is falsely low) , is severely anemic (low red blood cell count), iron deficient( HbA1c is falsely high) or is being treated blood transfusions or medications to increase the production of new red blood cells, the A1c test may not be accurate.

Thank you.
