[QUOTE="dnfuss, post: 98115, member: 15487"] Simply put, HgbA1c is a measure of glycation end-products bonded to your red blood cells. Doctors like this lab because they believe it gives them a window on your average blood glucose level over the last three months. All things being equal, it may. But while the correlation is pretty consistent over populations, it may not be accurate for a particular individual for a number of reasons. Some people are just outliers and the average blood glucose rate suggested by their HgbA1c simply isn't accurate in that person. They know this because they test their blood sugar very frequently and know what their actual average readings are. The most common reason for poor correlation between HgbA1c and average blood glucose levels is the patient's rate of red blood cell turnover. One thing that is known to raise the rate of red cell turnover is phlebotomy, either through voluntary blood donation or through medical phlebotomy by prescription. With a higher turnover rate, fewer glycation end-products will be attached to the red blood cells than if there had been a lower rate of turnover. If you've donated blood or undergone prescribed phlebotomy during the three months prior to testing HgbA1c, your HgbA1c percentage will tend to indicate a lower average glucose level than is actually the case, sometimes much lower. While HgbA1c is a lab worth running (I have it done every time I have blood work), its value is more for comparative purposes than as an absolute indicator of your average blood glucose. The levels with the most clinical value are post-prandial blood glucose and, to a lesser extent, fasting blood glucose. [/QUOTE]
