what does hemoglobin a1c indicate

The Hemoglobin A1C (HbA1c) test measures your average blood sugar levels over the past 2 to 3 months. It does this by calculating the percentage of your red blood cells that have glucose-coated hemoglobin. Here's what the results indicate:

• Normal: Below 5.7%
• Prediabetes: 5.7% to 6.4%
• Diabetes: 6.5% or above

This test is crucial for diagnosing prediabetes and diabetes, as well as monitoring how well your blood sugar is being managed over time. It provides a more comprehensive picture than daily blood sugar checks, which only show a snapshot of your glucose levels at a single point in time.

For people with diabetes, maintaining an A1C level below 7% is generally recommended to reduce the risk of complications. However, your target may vary based on your age, health conditions, and other factors. Always consult your healthcare provider for personalized advice.
