Understanding Your A1C: The Big Picture

The A1C test, also known as the HbA1c test, provides a crucial long-term perspective on your blood sugar control. Unlike a single blood glucose reading, which only reflects your sugar level at one specific moment, the A1C reflects your average blood sugar level over the past 2-3 months. It essentially measures the percentage of hemoglobin (a protein in your red blood cells) that has glucose attached to it. The higher the percentage, the higher your average blood sugar has been over that time period.

What Do A1C Numbers Mean?

Here’s a general breakdown of what different A1C ranges typically indicate:

  • Below 5.7%: This is considered normal.
  • 5.7% - 6.4%: This indicates prediabetes. You're at higher risk of developing type 2 diabetes.
  • 6.5% or higher: This indicates diabetes. Further testing will likely be needed to confirm the diagnosis.

Important Note: These are general guidelines. Your individual target A1C range may vary based on factors like age, overall health, and presence of other medical conditions. Always discuss your target A1C with your healthcare provider.

The Connection Between A1C and Daily Blood Sugar Fluctuations

While the A1C reflects an average, significant daily fluctuations in blood sugar can still impact the result. Frequent high and low readings, even if they balance out over time, can still lead to an A1C that doesn't accurately reflect your overall glycemic control. This is where Continuous Glucose Monitoring (CGM) can be incredibly helpful.
