The A1C test measures your average blood sugar levels over the past 2-3 months. The results are reported as a percentage. Here’s what the ranges mean:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or above
There isn't a specific 'highest' A1C level, but extremely high A1C levels (e.g., above 10%) indicate very poor blood sugar control and a high risk of diabetes complications. If your A1C is consistently high, it’s important to work with your healthcare provider to adjust your treatment plan.
