Quality Control Checks
What are quality control checks?
They ensure that you are doing a test correctly and
that your system is working properly.
When should I check my meter?
• If you leave the cap off the vial of test strips.
• Before using your meter for the first time.
• When you open a new vial of test strips.
• If you drop the meter.
• Whenever your result does not agree with the
way you feel.
• If you have repeated a test, and the blood
glucose result is still lower or higher than
expected.
• When you want to check the performance
of the meter and test strip.
