CONTROL SOLUTION TESTING

Press ▲ so that the control solution test symbol CtL appears in the upper right corner of the

display. You must mark the test before you apply control solution. Once you have completed

the test, you cannot change the marking. The meter is now ready to perform a control solution

test. If you decide not to do a control solution test, press ▲ again to remove CtL from

the display.

Prepare and apply control solution

Shake the control solution vial before each test. Remove the cap and squeeze the vial to

discard the rst drop. Then wipe the tip with a clean tissue or cloth. Hold the vial upside

down and gently squeeze a hanging drop. Touch and hold the hanging drop of control

solution to the narrow channel in the top edge of the test strip. Make sure the conrmation

window lls completely. Control solution should not be applied to the at face of the

test strip.

Read your result

When the conrmation window is full, the meter will count down from 5 to 1.

Your result will then appear on the display, along with CtL and the unit of measurement.



Check if the result is in range

Compare the result displayed on the meter to the control solution range printed on the test strip vial. Each vial of

test strips may have a dierent control solution range. If the results you get are not within this range, the meter and

test strips may not be working properly. Repeat the control solution test.

Out-of-range results may be due to:

• not following the instructions detailed in steps 1–7,

• expired or contaminated control solution,

• expired or damaged test strip,

• use of a test strip or control solution past its discard date, or

• a problem with the meter.

 CAUTION: The control solution range printed on the test strip vial is for OneTouch® Ultra® Control Solution only. It is not a

recommended range for your blood glucose level.

 CAUTION: If you continue to get control solution results that fall outside the range printed on the test strip vial, Do Not use the meter,

the test strips, or the control solution. Call OneTouch® Customer Care 0800 121200 (UK) or 1800 535676 (Ireland).
