A Hemoglobin A1c (HbA1c) test measures the percentage of hemoglobin in your red blood cells that has glucose attached to it. Because red blood cells live approximately 3 months, this test reflects your average blood sugar level over that period.
What This Test Measures
Hemoglobin A1c:
When glucose enters your bloodstream, some of it attaches to hemoglobin (the oxygen-carrying protein in red blood cells). The higher your blood sugar levels have been, the more glucose attaches. A1c is expressed as a percentage.
Understanding Your Results
• Normal: Below 5.7%
• Prediabetes: 5.7% to 6.4%
• Diabetes: 6.5% or higher
For people with diabetes, target A1c levels are typically below 7%, though individual goals may vary based on age, health status, and other factors. Consult your healthcare provider for personalized targets.
Who Should Consider This Test
• Adults age 45+ as part of routine diabetes screening (recommended every 3 years if normal)
• Anyone with risk factors for diabetes at any age:
– Overweight or obesity
– Family history of type 2 diabetes
– History of gestational diabetes
– Sedentary lifestyle
– High blood pressure
– Abnormal cholesterol levels
– Polycystic ovary syndrome (PCOS)
• People with diabetes to monitor blood sugar control (typically every 3-6 months)
• Those with prediabetes to monitor progression
