what glucose level is diabetes

Diabetes is diagnosed based on specific blood glucose levels. Here are the key thresholds:

• Fasting Blood Glucose Test:

  • Normal: Less than 100 mg/dL
  • Prediabetes: 100–125 mg/dL
  • Diabetes: 126 mg/dL or higher

• A1C Test:

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

• Oral Glucose Tolerance Test (OGTT):

  • Normal: Less than 140 mg/dL
  • Prediabetes: 140–199 mg/dL
  • Diabetes: 200 mg/dL or higher

If your results fall into the diabetes range, consult a healthcare provider for further evaluation and management.
