Comparing Control Solution Results
If the result is outside the range printed on the test strip bottle, repeat the
test. One or more of the following may have caused an out-of-range result:
• The meter was not placed in control solution mode before adding control
solution
• The control solution has expired or has been contaminated
• The control solution was stored below 35°F (2°C) or above
86°F (30°C)
• First drop of control solution was not discarded
• The test strip was not stored correctly
• The test strip was used after the expiration date of the bottle
• The test strip bottle was open for more than 90 days (3 months)
• The GLUCOCARD Vital meter has been damaged or has malfunctioned
• Contamination due to the tip of the control solution bottle touching the
test strip
