Hemoglobin A1c Test
The Hemoglobin A1c (HbA1c) Test is one of the most important tools for evaluating your long-term blood sugar control. Unlike a standard glucose test, which measures your blood sugar at a single moment in time, the HbA1c test reflects your average blood glucose levels over the past 2–3 months.
This test is commonly used to screen for prediabetes and diabetes, diagnose diabetes, and monitor how well blood sugar is being managed over time. Because it provides a broader picture of glucose control, the HbA1c test helps your healthcare provider evaluate your overall metabolic health and determine whether lifestyle changes or treatment plans are working effectively.
If you're at risk for diabetes, have already been diagnosed, or simply want to better understand your health, the Hemoglobin A1c test offers valuable insight into your body's ability to regulate blood sugar.
What Does This Test Measure?
The Hemoglobin A1c Test measures the percentage of hemoglobin—the protein in your red blood cells that carries oxygen—that has glucose (sugar) attached to it.
Because red blood cells live for approximately 120 days, the test reflects your average blood sugar over the previous two to three months, rather than your blood sugar at a single point in time.
Your healthcare provider uses this information to:
Determine whether your blood sugar is within a healthy range
Screen for prediabetes or diabetes
Monitor how well diabetes is being managed over time
Guide treatment recommendations and lifestyle modifications
Who Should Consider This Test?
The Hemoglobin A1c Test is recommended for:
Adults completing annual wellness screenings
Individuals with a family history of diabetes
People who are overweight or obese
Individuals with high blood pressure or elevated cholesterol
Women with a history of gestational diabetes
Individuals experiencing increased thirst, frequent urination, unexplained weight loss, or fatigue
Patients currently managing prediabetes or diabetes
Anyone interested in understanding their long-term metabolic health
Even if you feel healthy, routine screening can help identify changes before symptoms develop.
