Comparing Your Meter Result to a Lab Result
s
A common question is how the blood glucose results on your meter compare to the lab results. Your blood
glucose can change quickly, especially after eating, taking medication, or exercising. If you test yourself in the
morning, then go to the doctor’s office for a blood glucose test. The results will probably not match, even if you
are fasting. This is typically not a problem with your meter, it just means that time has elapsed and your blood
glucose has changed.
If you want to compare your meter result to the lab result, you must be fasting. Bring your meter to the
doctor’s office, and test yourself by fingertip within five minutes of having blood drawn from your arm by a
healthcare professional. Keep in mind that the lab could use different technology than your
EM44
blood
glucose meter, and that blood glucose meters for self testing generally read somewhat lower or higher than
the lab result.
For accuracy and precision data and for important information on limitations, see the instructions that come
with your test strips.
