[QUOTE="DavidGrahamJones, post: 1949571, member: 245335"] It is said that the HbA1c reflects something of an 8 - 12 week average. The theory behind the A1c test is that our red blood cells live an average of three months, so if we measure the amount of sugar stuck to these cells (which is what the hemoglobin A1c test does), it will give us an idea of how much sugar has been in the blood over the previous three months. The number reported in the A1c test result indicates the percentage of hemoglobin that has become glycated (stuck to sugar). While this sounds good in theory, the reality is not so black and white. The main problem is that there is actually a wide variation in how long red blood cells survive in different people. Researchers found that the lifetime of hemoglobin cells of diabetics turned over in as few as 81 days, while they lived as long as 146 days in non-diabetics. It's comparing apples with oranges.
