what is a good blood glucose reading

A good blood glucose reading depends on whether you are checking it fasting or after meals. Here are general guidelines:

• Fasting Blood Glucose (before eating):

  • Normal: 70–99 mg/dL
  • Prediabetes: 100–125 mg/dL
  • Diabetes: 126 mg/dL or higher

• Postprandial (2 hours after eating):

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

These ranges may vary slightly depending on individual health conditions and guidelines from your healthcare provider. Always consult your doctor for personalized targets.
