• Your hematocrit (percentage of your blood that is red blood cells)
is high (above 55%) or low (below 30%).
• You are severely dehydrated.
• You tested at a temperature near the low end of the operating
range (43°F ) and you get a high glucose result (i.e., greater than
180 mg/dL). In this situation, repeat the test in a warmer
environment with a new test strip as soon as possible.
For accuracy and precision data and for important information on
limitations, see the insert that comes with your test strips.

and laboratory results, follow a few basic guidelines:
Before going to the lab
• Perform a control solution test to make sure the meter is
working properly.
• Do not eat for at least eight hours before you test your blood.
• Take your meter with you to the lab.
While at the lab
• Conduct your meter test within 15 minutes of the lab test.
• Use only fresh, capillary blood obtained from the fingertip.
• Follow all instructions in this owner’s booklet for performing a blood
glucose test with your meter.
