• Confirm that you are using the same brand of control solution that was
provided with your kit.
• Make sure that you followed the test procedure correctly.
After checking all of the conditions listed above, repeat the quality control test with
a new test strip. If your results still fall outside of the control range shown on the
test strip vial (or on the foil pouch), your meter may be defective. Please contact
your local distributor for help.
Three levels of control solution are available labeled Control Solution 0, Control
Solution 1 and Control Solution 2. Control Solution 1 is sufficient for most all
self-testing needs. If you think your meter or strips may not be working correctly,
you may also want to do a level 0 or level 2 test. The ranges for CTRL 0, CTRL 1
and CTRL 2 are displayed on the test strip vial (or on the foil pouch). Simply repeat
step 4 through 6, using Control Solution 0 or Control Solution 2.
To confirm your results, Control Solution 0 tests should fall within the CTRL 0 range,
Control Solution 1 tests should fall within the CTRL 1 range and Control Solution 2
tests should fall within the CTRL 2 range. If the control solution test results do not
fall within their respective ranges, DO NOT use the system to test blood, as the
system may not be working properly. If you cannot fix the problem, please contact
your local distributor for help.
Please contact your local distributor for information on ordering the On Call
