Just came across an article on Glyco Mark - a test developed to measure post prandial sugars greater than 180 US blood sugars. It seems that your MD can order it with the common labs - Quest/LabQuest etc, and that it - along with A1c - can help monitor blood sugar levels. The Glyco Mark is specific for when you blood sugars are above that 180, and it is also for the last 2 weeks or 1 month vs. the A1c which is weighted for 50% in the past 2 weeks - . Does anyone have any experience with this? I searched Tu and Diabetes Book sites for this info and it doesn't show up - either my search technique is incomplete or the test might be referenced in another way. Hope to hear about it from others.
