Glycomark™ is the test that measures 1,5 Anhydroglucitol (1,5-AG), a monosaccharide that resembles glucose. It is consumed in food, circulates in the blood, and is usually retained by the kidneys. Blood levels of 1,5-AG will decrease as blood glucose increases to unhealthy levels.
A low level of 1,5-AG may indicate the presence of diabetes and should be investigated further. Higher levels are ideal.
