Understanding Your Blood Glucose Test Results
Blood glucose values will vary depending on food intake, medication, health, stress, and
(1)
exercise. The ideal ranges for adults without diabetes are
• less than 100 mg/dL (5.6 mmol/L) before meals.
• less than 140 mg/dL (7.8 mmol/L) two hours after meals.
It is important to consult with your physician or healthcare professional to determine an
appropriate target range for you.
What to Do If You Get a High or Low Reading
If the meter displays results that are "HI" or "LO", or you get a result that is more than
your high or low blood glucose threshold value AND you feel ill:
• Treat your diabetes according to the instruction from your doctor and/or consult your
healthcare provider.
• Test your meter with a control solution, refer to Control Solution Testing on page 31.
• Test again using fingertip with a new test strip.
If you still get a high or low reading, contact your healthcare professional immediately.
