The 1, 5-anhydroglucitol (1, 5-AG) assay and A1C/1. 5-AG assay combination for measuring blood glucose excursions in general and postprandial hyperglycemia in diabetic patients

摘要

The invention is a method of measuring blood glucose excursions in general, and postprandial hyperglycemia in diabetic patients in particular, by the 1,5-anhydroglucitol assay (1,5-AG) or A1C/1,5-AG assay combination. 1,5-AG levels and percent changes of 1,5-AG levels in short period are indicative of differing postmeal glucose levels in moderately-controlled diabetic patients with similar AlC levels. Thereby 1,5-AG assay is useful to identify diabetic patients who may be at risk for cardiovascular complications which would not be identifiable by AlC levels alone. Furthermore, ratios of AlC divided by 1,5-AG in each patient are superior indicators to 1,5-AG levels.
