10.5. IMPORTANT CONTROL SOLUTION INFORMATION
• Use only our control solutions with your meter.
• Do not use the control solution beyond the expiry date or 3 months after first opening.
Write the opening date on the control solution vial and discard the remaining solution
after 3 months.
• It is recommended that the control solution test be done at room temperature 68°F to
77°F / 20°C to 25°C. Make sure your control solution, meter, and test strips are at this
specified temperature range before testing.
• Shake the vial before use, discard the first drop of control solution, and wipe off the
dispenser tip to ensure a pure sample and an accurate result.
• Store the control solution tightly closed at temperatures between 35.6°F to 86°F / 2°C to
30°C. DO NOT freeze.
