A normal blood sugar level varies depending on the type of test used to measure it. Here are the normal ranges for different tests:

• Fasting Blood Sugar Test: A fasting blood sugar level of 70 to 100 mg/dL (3.9 to 5.6 mmol/L) is considered normal.

• A1C Test: An A1C below 5.7% is normal.

• Glucose Tolerance Test: At 2 hours, a blood sugar level of 140 mg/dL or lower is considered normal.

• Random Blood Sugar Test: A blood sugar level of 200 mg/dL or lower is considered normal.

Its important to note that these ranges may vary slightly depending on the source. Additionally, normal ranges may differ for individuals with diabetes or prediabetes. If you have concerns about your blood sugar levels, its best to consult with a healthcare provider.
