1-5 Anhydroglucitol

1,5-AG reflects hyperglycemia above the renal threshold over the preceding 1-2 weeks which is complimentary to HbA1c and Glycated Serum Protein determinations. The test provides a useful, unique perspective of patient’s recent hyperglycemic excursions, which may not be evident from standard glycemic markers. Hyperglycemic excursions may be associated with glycemic variability, which can be investigated through more frequent self-monitoring of blood glucose (SMBG) or continuous glucose monitoring (CGM).
