About Us

The GlycoMark test is an FDA-cleared, non-fasting serum or plasma test for monitoring blood glucose variability in people with diabetes. The GlycoMark test provides quantitative measurement of 1,5-anhydroglucitol (1,5-AG) in serum or plasma. The test is for professional use, and is indicated for the intermediate term monitoring of glycemic control in people with diabetes.

The GlycoMark 1,5-anhydroglucitol biomarker was discovered to be linked to diabetes by a Japanese researcher in the 1980s. Over 1,300 studies and abstracts have been detailed in publications and in the scientific community relative to 1,5-AG worldwide.
