An indicator A1c used to measure whether sugar is wellregulated may give a false low in study volunteers. Sugar sticks to everything including our red blood cells. Sugar circulating and sticking to our red blood cells is measured by a1c. An a1c of 5.7 or above means you are trending diabetic. An a1c of 6.5 and above indicates diabetes.
The underlying assumption is that our red blood cells lives for 3 months. That should mean that a1c measures how our body is regulating sugar for 90 days. However,if you are donating alot of blood you are disposing of alot of older cells which are replaced by new ones. These newer cells have less sugar exposure which will sckew your numbers lower. This will artificially deflate your a1c. If you have an a1c of 6 your actual number could be higher if you had not donated so much blood. You potentially could be 6 4 on the doors of being diabetic!
