UNDERSTANDING YOUR TEST RESULT-NORMAL BLOOD GLUCOSE RANGE
• The normal blood glucose range is 70 to 100 mg/dL (3.9 to 5.6 mmol/L) for fasting and less than
140 mg/dL (7.8 mmol/L) two hours after meals for a non-diabetic adult. Consult your healthcare
professionals to find out your target blood glucose value.
• If your blood glucose result seems unusually high or low, or inconsistent with your previous
results, check the followings:
1. Does the code number on the test strip vial match the code number on the meter?
2. Was the blood sample applied to the test strip immediately after removing it from the vial?
3. Was the size of the blood sample sufficient?
4. Was the test strip vial cap tightly sealed?
5. Were the test strips expired?
6. Were the test strips stored away from extreme temperatures in very cold or hot weather or from
areas of high humidity?
Then run a quality control check with your control solutions and a new test strip. If the control test
result is within the acceptable range, review testing procedure and repeat your blood glucose test
with a new test strip.
If your blood glucose value is still inconsistent with your previous results, glucose trend, or how
you feel, contact your doctor immediately for help.
