(1,5-Anhydroglucitol )

Glycomark (1,5-Anhydroglucitol) is a serum biochemical marker that best reflects post-meal glucose values over the past 2 weeks. 1,5-Anhydroglucitol molecule competes with glucose for reabsorption in the proximal tubules of the kidney. Therefore, every time glucose spikes over the renal threshold throughout the day, 1,5-Anhydroglucitol is excreted from the body.




  • 1,5AG is contained in food and in normal situation, oral intake and urinary excretion are balanced.


  • High levels of glucose block reabsorption of 1,5AG in the proximal tubule resulting to increased urinary excretion.


Only the GlycoMark® test reflects average maximum blood glucose over the past two weeks

  • Strong correlation with both microvascular and macrovascular outcomes
  • Strong correlation with fingerstick  SMBG, continuous glucose monitoring , OGTT and HbA1c
  • Measures post meal glucose excursions better than other monitoring methods
  • Shows effectiveness of therapy change in 2-4 weeks
  • Reveals recent deterioration in glucose control

The GlycoMark test is US FDA-cleared for intermediate monitoring of glucose control in people with diabetes and bears the CE mark for your added confidence.

GlycoMark Value Correlation to Estimated Average Peak Glucose (eAPG)

  • When A1C < 8%, 1,5-AG reveals differences in peak glucose

  • When A1C > 8%, 1,5-AG will almost always be <10 µg/mL due to depletion from constant hyperglycemic state
