CONTROL SOLUTION TESTING
Control solution testing
When to test with control solution
OneTouch® Ultra® Control Solution contains a known amount of glucose and is used to check that the meter and the test strips are
working properly.
How to test with control solution
Start with the meter off. If you have turned the meter on to change settings or review past results, turn it off.
Check the code on the test strip vial before inserting the test strip
Insert a test strip to turn on the meter
Make sure the three contact bars are facing you. Push the test strip in as far as it will go.
Do Not
bend the
test strip.
Match the code on the meter with the code on the test strip vial
If the code on the meter does not match the code on the test strip vial, press
▲
or
▼
to match the code
number on the test strip vial. The new code number will flash on the display for three seconds, and then stay
constant for three seconds. The display will advance to the screen with the flashing blood drop icon
R
.
If the codes already match, wait three seconds. The display will advance to the screen with the flashing blood
drop icon
R
.
Mark the test as a control solution test
IMPORTANT:
• Mark all control solution tests with
CtL
. This will stop them from being
stored as blood glucose results.
• Control solution results marked with
CtL
are not stored in the meter’s
memory.
CAUTION:
Do Not
swallow control solution; it is not for human consumption.
Do Not
apply control solution to the skin or eyes
as it may cause irritation.
Do a control solution test:
• to practice the test process instead of using blood,
• once a week,
• whenever you open a new vial of test strips,
• if you suspect the meter or test strips are not working properly,
• if you have had repeated unexpected blood glucose results (as
described in
Applying blood and reading results
in Section 3), or
• if you drop or damage the meter.
NOTE:
• Use only OneTouch® Ultra® Control Solution with your OneTouch®
UltraEasy® Meter.
• Control solution tests must be done at room temperature
(20–25
°
C). Make sure your meter, test strips, and control solution
are at room temperature before testing.
