Test strip functionality
Test strips enable a quantitative measurement of the glucose level in fresh whole blood. When the
gap for taking blood comes into contact with a drop of blood, it is automatically filled by simple cap-
illary action. The blood is sucked into the absorbing gap on the test strip and the monitor measures
the blood glucose level in the blood.
The test is based on the measurement of an electric current that is generated by the chemical reaction
of the glucose with the enzyme glucose dehydrogenase (Aspergillus oryzae) on the strip.
During the reaction, a mediator transports electrons through the electrode surface and so generates
a current.
The monitor analyses this current. The current flow is proportional to the glucose content in the blood
sample. The results are shown on the blood glucose monitor display. Only a small amount of blood
is required (0.6 microlitres) and the duration of measurement is approx. five seconds. The test strips
detect blood glucose values from 20 to 630 mg/dL (1.1 to 35.0 mmol/L).
