Control solution tests are an easy way to make sure your blood glucose meter is still working properly. To check your meter with a control solution, you can follow similar steps you would take to check your blood sugar.
- Insert a test strip into the meter. When you insert a strip in the meter, it will wake up the meter and the meter will say that it is checking the test strip.
- Notice the two different kinds of solutions. Control Solution 1 is your primary solution for tests. Control Solution 2 is a trusted backup. Unless Control Solution 1 has expired or the seal was broken when you received it, always start with Control Solution 1.
- Shake the control solution bottle. Squeeze one drop into the sink or trash before use. Squeeze the second drop of control solution onto a clean, hard, dry surface, like the top of the cap of the control solution bottle.
- Pick up the meter with the strip inserted and touch the strip to the drop of the control solution.
- The control result will show up on the screen in five seconds. Your meter can automatically tell the difference between blood and control solution.
- Check the side of the bottle that the test strips come in. There, you’ll see a guide. That guide shows a range for control solution tests, both for Control Solutions 1 and 2. If your result is within range, your meter is working as normal.
NOTE: If the strip is removed before you start, the screen will go blank. If a control is not performed within two minutes of inserting the strip, the screen will go blank. To check, remove and replace the strip, starting from Step 1.
If you get an out-of-range result during a control solution test, it may be caused by the following:
- An error may have occurred when performing the control solution test. Try another test and remember to follow the instructions carefully.
- The control solution may have expired or may have been contaminated. Check the expiration date on the control solution vial. Control solution is only good for six months after opening. Make sure the control solution vial is closed when not in use. If Control Solution 1 has expired or was left open, try a test with Control Solution 2 instead.
- The strip may have expired. Check the expiration date on the test strip vial.
- The test strip may have been damaged. This can be caused by extreme temperatures or by leaving the test strip vial cap open. Try another test using a new test strip.
- There may be a meter malfunction. If this is the case, contact our Member Support team for help.
- Do not use the meter for medical purposes until your control solution test results fall within the range marked on the test strip vials.
- Use only the provided control solution with provided test strips. Other brands of control solution or test strips will give inaccurate results.
- Always check the expiration date of the vials of the control solution. Do not use expired control solution.
- You can store the control solution closed and at room temperature at relative humidity between 10% and 90%. Do not freeze.
- Never touch the tip of the control solution bottle to the test strip; this will contaminate the remaining solution in the bottle.
It’s best to do a control solution test every week. You can also do a control solution test when you get a new batch of strips, or if you accidentally drop your meter and want to give it a checkup.
