About This Test

Reason to Check It

"Hemoglobin A1c (HbA1c) is a measurement of the percent of hemoglobin molecules bound to glucose by-products.  The HbA1c measurement reflects the average glucose level over the past 60-90 days, therefore, a high HbA1c test result reflects a high glucose level over time. As a diagnostic test, glycated hemoglobin has superiority over fasting glucose, as it can be measured in non-fasting states, has greater reproducibility, and gives a better picture of the trend of how high blood sugars are going after meals.

A Hemoglobin A1c of 5.7-6.4% is consistent with prediabetes, while an A1c equal to or greater than 6.5% is consistent with diabetes." - Dr. Alan Hopkins

Test Preparation

  • No special preparation is required before your sample collection.


Please Note: We recommend overnight fasting and an early morning blood draw for all tests, even if no special preparation is required. Remember, it is OK to drink plenty of water. Drinking water helps hydrate you and makes it easier for the phlebotomist to obtain your blood sample.
