Blood Glucose Tests
Comparing Your Meter Result to
a Laboratory Result
A common question is how the blood
glucose results on the meter compare to
the laboratory results. Your blood glucose
can change quickly, especially after
eating, taking medication, or physical
activity. If you test yourself in the morning,
then go to your healthcare professional's
office for a blood glucose test, your test
results will probably not match, even if you
are fasting. This is typically not a problem
with the meter, it just means that time has
elapsed and your blood glucose level has
changed.
Although you always apply fresh capillary
whole blood to the test strip, the system
has been calibrated to deliver plasma-like
values for easier comparison to laboratory
results.
If you want to compare your meter result
to the laboratory result, you must be
fasting. Take the meter to your healthcare
professional's office and test yourself by
fingerstick within 5 minutes of having
blood drawn from your arm by a
healthcare professional. Keep in mind that
the laboratory uses different technology
than the meter.
