The A1C level (also known as HbA1c or hemoglobin A1C) is a blood test that measures your average blood sugar levels over the past 2 to 3 months. It is expressed as a percentage and is commonly used to diagnose and monitor diabetes and prediabetes.

A1C Ranges:

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

How It Works:

The A1C test measures the percentage of red blood cells that have glucose-coated hemoglobin. Since red blood cells regenerate every 3 months, the test provides a long-term view of blood sugar control.

Why It Matters:

  • Diagnosis: Helps identify prediabetes or diabetes.
  • Monitoring: Tracks how well diabetes is being managed.
  • Goals: For most people with diabetes, the target A1C is below 7%, but this may vary based on individual health conditions.

Factors Affecting Accuracy:

Certain conditions like anemia, kidney disease, or blood disorders can affect A1C results. Always consult your doctor for personalized advice.
