On Call Extra Control Solution 3 bottles (2 mL/bottle).
The On Call® Extra Glucose Control Solution contains a known concentration of glucose.
It is used to confirm that your Extra Glucose Test Strips and the meter are working together properly and that you are performing the test correctly.
Three levels of control solution are available labeled Control Solution 0, Control Solution 1 and Control Solution 2. Control Solution 1 works for almost all self-testing needs. If you think your meter or strips may not be working correctly, you may also want to do a level 0 or level 2 test.
For use with the On Call® Extra.
Follow the user manual insert for complete instructions on how to use the control solution
