GlycoMark®

Cleveland HeartLab G, Metabolic, New Tests, Test

The GlycoMark® test is a surrogate marker to detect frequent and high glycemic excursions in diabetic patients and measures blood levels of 1,5 anhydroglucitol (1,5-AG), a glucose-like sugar found in food.

When blood glucose levels are well controlled, most circulating 1,5-AG is reabsorbed in the kidneys instead of being excreted in the urine. In healthy individuals, circulating levels of 1,5-AG are high, with median values exceeding 20 µg/mL.

However, when blood glucose levels are high, 1,5-AG reabsorption is blocked and a majority is excreted in the urine. Blood glucose spikes of greater than 180 mg/dL result in 1,5-AG loss in the urine. Individuals with type 2 diabetes have low circulating levels of 1,5-AG2,4. Unlike HbA1c testing, which measures an individual’s average glucose over a 2-3 month period, the GlycoMark® test reveals more recent deteriorations in glucose control.
