Ordering the GlycoMark Test
The GlycoMark test measures 1,5-anhydroglucitol, a marker that reflects recent spikes in blood sugar levels, providing information that is different from the three-month average shown by Hemoglobin A1C. This test is especially useful for tracking short-term changes in blood sugar, which can help guide adjustments in diet or treatment plans. Interestingly, GlycoMark can also be helpful for people with conditions like adrenal dysfunction or polycystic ovary syndrome, not just those with diabetes.
Ordering the GlycoMark test offers several specific benefits:
- Detects frequent high blood sugar episodes that may not show up on A1C tests.
- Helps monitor the effects of dietary changes on blood sugar control.
- Supports early detection of blood sugar spikes in people with insulin resistance.
- Assists in evaluating blood sugar patterns in people with hormonal imbalances, such as elevated estrogen in males.
- Provides a more complete picture of blood sugar control for people using new diabetes medications.
Who Might Benefit from Short-Term Blood Sugar Monitoring
Someone who has been working hard to manage their blood sugar but still feels tired after meals may want to know if their efforts are making a difference. This test can help reveal if there are hidden spikes in blood sugar that other tests might miss.
Ordering this test may also be helpful in these situations:
- People with a family history of diabetes who want to track early changes in blood sugar.
- Those with polycystic ovary syndrome who are monitoring insulin resistance.
- People with adrenal gland issues who need to check for blood sugar swings.
- Men with high estrogen levels who are tracking metabolic changes.
- People who have recently started a new exercise routine and want to see its effect on blood sugar patterns.
This test should be ordered to catch short-term blood sugar spikes that can lead to nerve or blood vessel problems if left unchecked. Delaying this test could mean missing early signs of blood sugar swings, making it harder to adjust your plan before complications develop.
Preparing for Short-Term Glucose Marker Testing
No fasting is needed before taking the GlycoMark test, so you can eat and drink as usual before your blood draw. Always follow any directions your doctor or healthcare provider gives you to make sure your results are as helpful as possible.
