Control Solution Testing: How To Test:

 

Control Solution Testing:

  • 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.
1. Check the code on the test strip vial before inserting the test strip.
2. 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.
3. 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.
      • If the codes already match, wait three seconds. The display will advance to the screen with the flashing blood drop icon.
4. Mark the test as a control solution test.
      • 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.
      • 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.
5. Prepare and apply control solution.
      • Remove the cap and squeeze the vial to discard the first drop. 
      • Shake the control solution vial before each test.​​​​​
      • 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.
6. 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.
7. 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 1–7
      • Expired or contaminated control solution
      • Expired or damaged test strip
      • Use of a test strip or control solution past its discard date
      • 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. If the problem persists, contact OneTouch® Customer Care.
