Note regarding function of test strips
The test strips enable a quantitative measurement of the glucose content of capillary whole blood.
When the slit for collecting blood comes into contact with a drop of blood, it fills automatically through
simple capillary action. The blood is sucked into the absorbing slit of the test strip and the measuring
device measures the glucose level of the blood.
The test is based on the measurement of an electric current caused by a chemical reaction between
the glucose and the enzyme glucose oxidase (aspergillus niger) on the test strip. During the reaction,
a mediator transports electrons through the electrode surface, thereby generating a current. The
measuring device analyses this current. The flow of current is proportional to the glucose content of
the blood test. The results are shown in the display of the measuring device. Only a small quantity of
blood is required (0.6 microlitres) and the measurement takes approx. five seconds. The strips can
detect blood glucose levels in the range 20 – 630 mg/dL.
Chemical components of the test strip sensor
• Glucose oxidase ≥ 0.6 IU
• Electron shuttle ≥ 0.03 mg
• Non-reactive components ≥ 0.06 mg
Note regarding function of the control solution
The control solution contains a fixed concentration of glucose that reacts with the test strip. A test
with the control solution is performed in the same way as a blood test, but the control solution is
used instead of blood. The measurement result from the control solution must lie within the results
range. This results range is printed on every test strip container.
Chemical composition
The control solution is a red solution with the following D-glucose level (in percentage shares):
