Blood Glucose Test Strips
The On Call®Advanced Blood Glucose Test Strips or On Call®Chosen Blood
Glucose Test Strips can work with the On Call®GK Dual Blood Glucose & Ketone
Meter to measure the glucose concentration in your whole blood.
The On Call®Advanced Blood Glucose Test Strips and On Call®Chosen Blood
Glucose Test Strips are thin strips with a chemical reagent system. 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. A reaction takes place,
and a transient electrical current is formed. 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 calibrated to display plasma-like
concentration 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 as 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 and until the meter begins to count down. If you applied a blood, but
meter does not start to count down, you may reapply a second drop of blood within
3 seconds. If the check window does not fill and meter starts to countdown, then do
not add more blood to the test strip. If you do then you may get an E-5 message or
