What this laboratory test evaluates
Hemoglobin A1c with eAG
This test combines the measurement of Hemoglobin A1c (HbA1c) with the Estimated Average Glucose (eAG). The American Diabetes Association (ADA) suggests getting HbA1c twice a year if your blood sugar is stable, and every three months if it's not well controlled. The eAG translates the HbA1c percentage into the same units used by daily blood sugar tests (mg/dL or mmol/L), making it easier for patients to relate to their day-to-day glucose readings. This test provides clarity on how well blood sugar is controlled over time to guide treatment adjustments. High HbA1c and eAG levels indicate that a patient's blood sugar, suggesting a need for adjustments in treatment.
What patients is this test right for?This test is especially important for people with diabetes or those at risk of developing or already diagnosed and managing diabetes. It helps in: • Monitoring long-term blood sugar control
• Adjusting diabetes treatment plans if necessary
• Reducing the risk of diabetes-related complications
What type of sample is required for this test?1 mL of whole blood collected in an EDTA (lavender-top) tube.
