Why Perform Control Tests

Performing a control test lets you know that the meter and test strips are working
properly to give reliable results. You should perform a control test when:
• You open a new box of test strips
• You left the test strip container open
• You want to check the meter and test strips
• Your test strips were stored in extreme temperature and/or humidity
• You dropped the meter
• Your test result does not agree with how you feel
• You want to check if you are testing correctly
