is 5.4 a1c prediabetes

An A1C level of 5.4% is considered normal and does not indicate prediabetes. According to the CDC and other medical guidelines:

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

A 5.4% A1C falls within the normal range, meaning your average blood sugar levels over the past 2-3 months are healthy. However, it's always a good idea to discuss your results with your healthcare provider to ensure you maintain healthy habits and monitor your risk factors.
