Tracking your blood glucose concentration through frequent testing is
an important part of proper diabetes care. Your diabetes health care
professional will help you to decide the normal target range for your
glucose levels. They will also help you determine when and how often
to test your blood glucose. Some suggested times are:
When you wake up (fasting level)
Before breakfast
1-2 hours after breakfast
Before lunch
1-2 hours after lunch
Before or after exercise
Before dinner
1-2 hours after dinner
Before bedtime
After a snack
At 2 or 3 AM, if taking insulin
You may need to test more often whenever :
You add or adjust your medication for diabetes.
You think your blood glucose levels may be too low or too high.
You are ill, or feeling uncomfortable over long periods of time.
Talk to your diabetes healthcare professional to set your own daily
target ranges.
Use the logbook to record your blood glucose measurements and
related information. Bring the logbook with you when visiting your
physician so that you can determine how well your blood glucose is
being controlled. This can help you and your health care professional
make the best decisions about your glucose control plan.

Comparing Meter
and Laboratory Results
Your Blood Glucose Monitoring System and laboratory
results both report the glucose concentration in the serum or plasma
component of your blood. However, the results may differ somewhat
due to normal variation. This is expected, but the difference under
normal operating conditions should be no greater than 20%.
Users should make accurate comparisons periodically between meters
and laboratory results. Follow the guidelines below.
Before you go to the lab:
At the lab:
On Call Plus
®
Bring your meter, test strip and control solution with you to the lab.
Make sure your meter is clean.
Perform a quality control test to make sure the meter is working
properly.
Comparisons will be more accurate if you do not eat for at least four
hours (preferably eight hours) before testing.
Wash your hands before obtaining a blood sample.
Obtain blood samples for a laboratory test and for your meter within
10 minutes of each other. This will ensure an accurate comparison
of results.
Never use your meter with blood that has been placed in test tubes
containing fluoride or other anticoagulants. This will cause falsely
low results.
