Blood Glucose Test Strips
The

Extra
Blood Glucose
Test Strips are thin strips. The strips have a
chemical reagent system. They work with the
On Call
®
Extra Mobile
Blood Glucose
Meter to measure the glucose concentration in whole blood. After the strip is
inserted into the meter, blood is applied to the sample tip of the test strip. The blood
is then automatically absorbed into the reaction cell where the reaction takes place.
A transient electrical current is formed during the reaction. The blood glucose
concentration is calculated based on the electrical current detected by the meter.
The result is shown on the meter display. The meter is set to display plasma
equivalent results.
IMPORTANT:
Apply sample only to the sample tip of the test strip. Do not apply
blood or control solution to the top of the test strip. This may result in an inaccurate
reading.
Hold the blood drop to the sample tip of the test strip until the check window is
completely full. The meter will then begin to count down. If you applied blood but do
not see the countdown start, you may reapply a second drop of blood within 3
seconds. If the check window does not fill and the meter starts to count down, then
do not add more blood to the test strip. If you do then you may get an E-5 message
or an inaccurate test result. In this case, if the meter begins to count down and the
check window does not fill, discard the strip and begin the test again with a new test
strip.
