What does a glycomark of 5 indicate

A relatively new laboratory test that indicates whether someone has had high blood glucose levels over the previous one to two weeks. The GlycoMark test can be especially useful for determining whether a person experiences blood glucose “spikes” after meals.

Currently, the most commonly used laboratory test for evaluating blood glucose control is the HbA1c test. A person’s HbA1c test result is a measure of his overall blood glucose control over the preceding two to three months.

GlycoMark was approved for marketing in the United States by the US Food and Drug Administration in 2003. The test measures the level of a type of sugar called 1,5-anhydroglucitol (1,5-AG) in the blood. Like glucose, 1,5-AG is absorbed by the kidneys, with some of both excreted in the urine. The two are chemically very similar – so similar, in fact, that 1,5-AG “competes” with glucose for reabsorption back into the bloodstream from the kidneys. The result is that when someone’s blood glucose level rises above about 180 mg/dl, 1,5-AG begins to be excreted in the urine at a greater level, and the level in the blood goes down; it takes one to two weeks to return to normal.

There is very strong scientific evidence that keeping blood glucose levels close to the normal range can help reduce the risk of diabetic complications, such as diabetic eye disease, kidney disease, and nerve damage. There is also some evidence that tight blood glucose control can lower the risk of heart disease, the leading cause of death in people with diabetes.

I appreciate your excellent explanation here and now. Thanks.

Welcome to the group, ilene22. Glycomark of 5 indicates that your post-meal blood glucose in the previous two weeks has been between 200 and 225 mg/dl.

Reference range for Glycomark: Adult Female: 6.8 - 29.3 Adult Male: 10.7 -32.

Glycomark of 10 and above are considered good.

At present Glycomark is not an universally used marker. More commonly used marker is HbA1c. Hope this helps.
