what should fasting glucose level be

Fasting glucose levels are an important indicator of blood sugar control. Here are the general guidelines:

• Normal: Less than 100 mg/dL (5.6 mmol/L)
• Prediabetes: 100 to 125 mg/dL (5.6 to 6.9 mmol/L)
• Diabetes: 126 mg/dL (7.0 mmol/L) or higher on two separate tests

It's important to note that these values may vary slightly depending on the laboratory and individual health conditions. Always consult with your healthcare provider for personalized advice and interpretation of your results.
