Measuring Principle
The enzyme on the test strip, glucose dehydrogenase, in the presence of the coenzyme (PQQ),
converts the glucose in the blood sample to gluconolactone. This reaction creates a harmless DC
electrical current that your meter interprets for your blood glucose. The sample and environmental
conditions are also evaluated using a small AC signal.
Blood glucose concentrations may be measured in whole blood or plasma. Although you always
apply whole blood to the test strip, your meter displays blood glucose results that relate either
to whole blood or plasma. To see whether your blood glucose meter displays results relating to
whole blood or plasma, see the package insert that came with your test strips. You will also find
information on how the system works, on the test principle and on reference methods.
