Chapter 2: Control Testing
Why Perform a Control Test
Performing a control test lets you know that the meter and test strips are working properly. You should
perform a control test when:
• You open a new box of test strips
17
• You left the test strip container open or you think the test strips have been damaged
• The test strips were stored in extreme temperatures and/or humidity
• You want to check the meter and test strips
• You dropped the meter
• Your test result does not match how you feel
• You want to check if you are testing correctly
