SPOC Glucose Control Solution
On Call Extra Control Solution
87 in stock
The Control Solution verifies the proper operation of your glucose meter by checking the test strips and meter against a pre-calibrated control solution.
Three levels of control solution are available labeled Control Solution 0, 1 and 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.
