Fasting blood glucose

• One reading is not a diagnosis. The ADA requires a repeat abnormal test, or a second abnormal test type, to diagnose diabetes.
• Illness, stress, steroid medication and a short fast can all raise a single reading.
• This interprets a value you already have. It does not estimate your glucose.
