What is A1C
Hemoglobin A1C (Known as HbA1C or A1C) is measured in Patients with diabetes, an index of average blood glucose foe the previous three to four months. A1C is glucose attached to your hemoglobin, this is a protein found in red blood cells that transports Oxygen from the lungs to other parts of the body. The glucose in A1C is Irreversibly bound to one or both beta chains of hemoglobin. Glucose binds to hemoglobin continuously throught the life span of the red blood cells. Since the lifespan of a red blood cell in the circulation is approximately 120 days, A1C is an index of average blood glucose over 120 days. However, blood glucose levels in the preceding 30 days contribute more to high levels of A1C than so blood glucose levels 90 to 120 days earlier. This is the reason why the levels of A1C can increase or decrease relatively quickly with big changes in blood glucose.
The Normal level of A1C in people without diabetes is in the range of 4.4 to 5.6%. It is a fact that people with diabetes have higher levels of A1C. So, one must regularly check one’s A1C levels. This is the best measurement of our blood glucose control that we have now. This tells us what percentage of our hemoglobin -the protein in our blood cells that carry Oxygen has glucose sticking to it.
It is advised to keep your A1c below 5.6 If your A1C is between 5.7-6.4% you are considered Pre-diabetic. If your A1C is 6.5 or higher you are diabetic. It is good for you to ask your Physician to check your A1C whenever you go for blood test. we may think we are normal but there may be a surprise lurking in your blood for you.
