what are the glucose levels for diabetes

The glucose levels used to diagnose diabetes are typically measured through blood tests. Here are the key ranges:

• Normal: Fasting blood glucose level below 100 mg/dL (5.6 mmol/L).
• Prediabetes: Fasting blood glucose level between 100-125 mg/dL (5.6-6.9 mmol/L).
• Diabetes: Fasting blood glucose level of 126 mg/dL (7.0 mmol/L) or higher on two separate tests.

Additionally, the A1C test measures average blood glucose levels over the past 2-3 months:

• Normal: A1C below 5.7%.
• Prediabetes: A1C between 5.7% and 6.4%.
• Diabetes: A1C of 6.5% or higher.

If you suspect you have diabetes or prediabetes, consult a healthcare professional for proper testing and diagnosis.
