Test With Control Solution:
- OneTouch Verio® 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 Verio® Level 3 Control Solution or OneTouch Verio® Level 4 Control Solution with your OneTouch Verio® 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.
- CAUTION:
- Do Not swallow or ingest control solution.
- Do Not apply control solution to the skin or eyes 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.
Do A Control Solution Test:
- Whenever you open a new vial of test strips.
- If you suspect that the meter or test strips are not working properly.
- If you have had repeated unexpected blood glucose results.
- If you drop or damage the meter.
Performing A Control Solution Test:
1. Insert a test strip to turn the meter on
- Wait for the Apply Blood screen to appear on the display.
- Note: The same Apply Blood screen that appears during a blood glucose test also appears during a control solution test.
2. Prepare the control solution
- Remove the vial cap and place it on a flat surface with the top of the cap pointing up.
- Squeeze the vial to discard the first drop.
- Wipe both the tip of the control solution vial and the top of the cap with a clean, damp tissue or cloth.
- Then, squeeze a drop into the small well on the top of the cap or onto another clean, non-absorbent surface.
3. Apply the control solution
- Hold the meter so that the side edge of the test strip is at a slight angle to the drop of control solution.
- Touch the channel on the side of the test strip to the control solution. Wait for the channel to fill completely.
4. Read your result
- The meter will count down from 5 to 1. Your result is displayed along with the date, time, unit of measure, and
Control solution. - The meter automatically marks the result as a control solution test.
- CAUTION: If the words Control solution do not appear on the screen, this result will be included in your averages and your averages will change too. Repeat the test with a new test strip. If the problem persists, contact OneTouch® Customer Care.
5. Check if the result is in range
- Each vial of test strips has both OneTouch Verio® Level 3 Control Solution and OneTouch Verio® Level 4 Control Solution ranges printed on its label. Compare the result displayed on the meter to either the OneTouch Verio® Level 3 Control Solution or OneTouch Verio® Level 4 Control Solution range printed on the test strip vial, depending on the type of control solution you used.
- Out-of-range results may be due to:
- Not following the instructions above in this article.
- Control solution is contaminated, expired, or past its discard date.
- Test strip or test strip vial is damaged, expired, or past its discard date.
- Meter, test strips and/or control solution were not all at the same temperature when the control solution test was performed.
- A problem with the meter.
- Dirt or contamination in the small well on the top of the control solution cap (see Step 2 instructions above in this article).
- After getting a control solution result:
- Once you have a control solution result, you may:
- Press and hold
to return to the Main Menu. - Or, press and hold OK for several seconds until the meter turns off. The meter will also automatically turn off if left alone for two minutes.
6. Cleaning
- Clean the top of the control solution cap with a clean, damp tissue or cloth.
- Control solution results can be seen when reviewing past results, but are not included in result averages.
- 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, test strips, or control solution. Contact OneTouch® Customer Care.
- The control solution ranges printed on the test strip vial are for control solution tests only and are not recommended ranges for your blood glucose level.
