CONTROL SOLUTION TESTING
Prepare and apply control solution
Shake the control solution vial before each test. Remove the cap and squeeze the vial to
discard the first 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 confirmation
window fills completely. Control solution should not be applied to the flat face of the
test strip.
Read your result
When the confirmation 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 measure.
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 different 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 1–5,
• 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 the OneTouch® Customer Care Line at 1 800 663-5521.
