Diazyme 1,5-anhydroglucitol (1,5-AG) Assay is an enzymatic method intended for the quantitative determination of 1,5anhydroglucitol (1,5-AG) in serum or plasma. The 1,5-AG Assay is for the intermediate term (preceding 1-2 weeks) monitoring of glycemic control in people with diabetes. For in vitro diagnostic use only.

Diazyme's 1.5-AG assay is an enzymatic method intended for the quantitative determination of 1,5-anhydroglucitol (1,5-AG) in serum or plasma. The assay uses the enzyme pyranose oxidase (PROD) to oxidize the 2nd position hydroxyl group of 1,5-AG and to detect the generated hydrogen peroxide by colorimetry using peroxidase (POD). To eliminate reactive glucose in sample, it is pretreated by enzymatic reactions using hexokinase and pyruvate kinase (PK). Hexokinase uses adenosine triphosphate (ATP) to convert glucose into non-reactive glucose-6-phosphate (G-6-P), generating adenosine diphosphate (ADP). The reaction is driven to completion with PK, as ADP is phosphoralated to ATP during the conversion of phosphoenolpyruvate (PEP) into pyruvate.

The GlycoMark™ test provides quantitative measurement of 1,5-anhydroglucitol (15AG) 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™ reagents provide for a fully automated enzymatic test for 15AG. The assay requires the two-reagent boxed set (Reagent 1 and Reagent 2) and the 15AG standard (purchased separately). A two-level control set ("Low" and "High") is also available separately.
