Decoding HbA1c Test for Blood Sugar - How does the measure work?

How does the measure work?

Blood glucose tends to bind itself to the surface of Red Blood Corpuscles (red due to the presence of oxygen-carrying compound, hemoglobin).

The average lifespan of an RBC is 120 days ie 3-4 months. Therefore, measuring the number of red blood cells with glucose attached to them gives an idea of the blood glucose levels over the past 120 days.

Higher the levels of glucose in the blood more will be the number of RBCs with an appendage of glucose. Since raised blood sugar indicates to considerable increase in the risk of improper blood circulation, heart disease (cardiac arrests), stroke, and vascular complications of diabetes like damage to the blood vessels and kidneys, neuropathy, gangrene, retinopathy, gastroparesis, erectile dysfunction, and poor healing of injuries and wounds, it becomes imperative to control blood glucose at all times.(5^✔ ✔Trusted Source
