This isolation GlycoMark test measures 1,5-anhydroglucitol (1,5-AG), a biomarker that reflects short-term (1-2 week) blood sugar variability and post-meal glucose spikes. It is primarily used to monitor glycemic control in people with diabetes, particularly for identifying high glucose levels after meals that may not be captured by HbA1C alone. This evaluation includes:

• GlycoMark

Calorie-fasting is not required for the GlycoMark test, as it is designed to reflect glucose levels under normal conditions. However, it may be recommended based on other tests you are performing.
