Details
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.
- Hemoglobin A1c
- eAG (mg/dL)
- eAG (mmol/L)
Estimated days for results: Results should be available in 2 - 5 business days after the sample is collected
