Testing With Control Solution:
Control Solution Testing Precautions:
- OneTouch Ultra Plus™ Control Solution is used to check that the meter and test strips are working together properly and that the test is performing correctly. (Control solution is available separately.)
- Note:
- Use only OneTouch Ultra Plus™ Level 3 Control Solution or OneTouch Ultra Plus™ Level 4 Control Solution with your OneTouch Ultra Plus Flex™ Meter. Either level can be used to check your system.
- When you first open a new vial of control solution, record the discard date on the vial label. Refer to the control solution insert or vial label for instructions on determining the discard date.
- Tightly close the cap on the control solution vial immediately after use to avoid contamination or damage.
- For more information on testing:
- CAUTION:
- Do Not swallow or ingest control solution.
- Do Not apply control solution to the skin, eyes, ears or nose as it may cause irritation.
- Do Not use control solution after the expiration date (printed on the vial label) or the discard date, whichever comes first, or your results may be inaccurate.
When To Do A Control Solution Test:
