Comparing Your Meter Result To A Lab Result
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
EASYMAX
®
Voice
Blood Glucose Meter, and that blood glucose meters for self testing
generally read somewhat lower or higher than the lab result.
In comparison to the YSI, EASYMAX® met the EN ISO 15197:2013 standard, whereby 95% of the
blood glucose values measured must lie within the following ranges: either ±15 mg/dL (± 0.83
mmol/L) of the measured average value when using the reference measuring procedure for blood
glucose concentrations <100 mg/dL (<5.55 mmol/L) or ±15% for blood glucose concentrations of
≥
100 mg/dL (
≥
5.55 mmol/L). 99% of the individual measured blood glucose values must fall within
zones A and B of the Consensus Error Grid (CEG) for diabetes type 1.
For accuracy and precision data and for important information on limitations, see the instructions
that come with your test strips.
