Hemoglobin (Hb) A1c With GlycoMark® Reflex

When to Consider This Test

• If you have been diagnosed with Type 1 or Type 2 diabetes and need to track the effectiveness of your treatment plan and identify glucose fluctuations.
• When your healthcare provider recommends a more detailed view of your glucose control, particularly post-meal blood sugar levels, which A1c alone might not capture.
• If you are experiencing symptoms that could indicate blood sugar imbalances, such as increased thirst, frequent urination, unexplained weight changes, blurred vision, or persistent fatigue.
• As part of a routine wellness check, especially if you have risk factors for diabetes or a family history of the condition.

Who Benefits from This Test?

• Individuals diagnosed with diabetes who need comprehensive monitoring of both long-term (HbA1c) and short-term (GlycoMark®) glucose control.
• People with prediabetes or those at high risk for developing diabetes (e.g., due to family history, obesity, or lifestyle) who want a detailed assessment of their blood sugar management.
• Anyone seeking to understand the effectiveness of their current diabetes treatment plan, especially concerning post-meal glucose spikes.
• Individuals whose healthcare provider recommends a deeper insight into their glycemic fluctuations beyond standard A1c testing.

Commonly Used For Diagnosis Of

This comprehensive test is primarily used for the diagnosis and monitoring of:

• Type 1 and Type 2 Diabetes: Providing both long-term (HbA1c) and short-term (GlycoMark®) insights into blood glucose control, crucial for effective disease management.
• Prediabetes: Identifying individuals at risk of developing Type 2 diabetes by detecting elevated glucose levels that are not yet in the diabetic range.
• Insulin Resistance: Although not a direct measure, persistent elevated glucose levels (reflected by A1c and GlycoMark®) are indicators often associated with insulin resistance.
• Effectiveness of Diabetes Treatment: Assessing how well current dietary changes, exercise, and medications are controlling blood sugar levels, especially post-meal glucose spikes.
• Unexplained Hyperglycemia: Helping to identify the cause of persistently high blood sugar, particularly if symptoms of diabetes are present.
• Monitoring Glucose Fluctuations: GlycoMark® is especially useful for uncovering day-to-day and post-meal glucose variations that traditional A1c might miss, aiding in fine-tuning treatment.

Important Considerations and Cautions

It is important to discuss your test results with a healthcare provider, especially if you are taking medications such as SGLT2 inhibitors (e.g., INVOKANA®) or have certain medical conditions like kidney disease or pregnancy. These factors can significantly affect the interpretation of GlycoMark® levels. Individuals on SGLT2 inhibitors may show falsely low 1,5-AG levels due to the medication preventing its reabsorption in the kidneys.

Additionally, conditions such as persistently positive urinary glucose, hyperthyroidism, advanced cirrhosis, and prolonged inability to eat orally may also influence 1,5-AG values. Medications like certain Chinese medicines or steroids can also impact results. Always interpret these results in conjunction with your clinical history and other diagnostic findings.
