Control solution testing:
Control solution testing precautions:
- OneTouch Select® 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:
- 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.
- Do Not open the test strip vial until you are ready to remove a test strip and perform a test. Use the test strip immediately after removing it from the vial, especially in high humidity environments.
- Control solution tests must be done at room temperature (20-25°C). Make sure your meter, test strips and control solutions are at room temperature before testing.
- 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 expiry date (printed on the vial label) or the discard date, whichever comes first, or your results may be inaccurate.
Do a control solution test:
- 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.
Preparing your meter for a control solution test:
1. Insert a test strip to turn the meter on
-
- Insert the test strip with the test strip port and contact bars facing you.
2. Wait for the flashing blood drop icon 
to appear on the display
Preparing the control solution:
1. Before removing the cap, shake the vial gently
2. Remove the vial cap and place it on a flat surface with the top of the cap pointing up
3. Squeeze the vial to discard the first drop
4. Wipe both the tip of the control solution vial and the top of the cap with a clean, damp tissue or cloth
5. Squeeze a drop into the small well on the top of the cap or onto another clean, non-absorbent surface
Applying the control solution:
1. Hold the meter so that the channel at the top edge of the test strip is at a slight angle to the drop of control solution
2. Touch the channel on the top edge of the test strip to the control solution
3. Wait for the channel to fill completely
Viewing your control solution result:
- After the control solution is applied, the meter will count down until the test is complete. Your result is displayed along with the unit of measure. Your meter will not display a Range Indicator Arrow with a control solution result.
- NOTE: Your meter does not store a control solution result after it is turned off. When you turn your meter on, your last blood glucose result will appear along with the History Mode icon (
).
Checking if the result is in range:
- Each vial of test strips has the OneTouch Select® Plus Mid Control Solution range printed on its label. Compare the result displayed on the meter to the OneTouch Select® Plus Mid Control Solution range printed on the test strip vial.
- If your control solution result falls outside the expected range, repeat the test with a new test strip.
- CAUTION:
- The control solution range printed on the test strip vial is for control solution tests only and is not a recommended range for your blood glucose level.
Causes of out-of-range control solution results:
- Out-of-range results may be due to:
- Not following the instructions for performing a control solution test.
- Control solution is contaminated, expired, or past its discard date.
- Test strip or test strip vial is damaged 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.
- 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 Customer Care.
Cleaning the control solution cap:
- Clean the top of the control solution cap with a clean, damp tissue or cloth.
