TESTING YOUR BLOOD GLUCOSE
CAUTION: Dehydration and low glucose results
Severe dehydration resulting from excessive water loss may cause false low results. If you think you are suffering from severe
dehydration, contact your healthcare professional immediately.
CAUTION: Low glucose results
If your test result is lower than 70 mg/dL or is shown as LO, it may mean hypoglycemia (low blood glucose). This may require
immediate treatment according to your healthcare professional’s recommendations. Although this result could be due to a
test error, it is safer to treat first, then do another test.
CAUTION: High glucose results
If your test result is higher than 180 mg/dL, it may mean hyperglycemia (high blood glucose). If you are uncertain about this
test result, consider re-testing. Your healthcare professional can work with you to determine what actions, if any, you should
take if your results are higher than 180 mg/dL.
If your meter displays HI, you may have a very high blood glucose level (severe hyperglycemia) exceeding 600 mg/dL.
Re-check your glucose level. If the result is HI again, this may indicate a severe problem with your blood glucose control
and it is important you obtain and follow instructions from your healthcare professional without delay.
CAUTION: Repeated unexpected glucose results
If you continue to get unexpected results, check your system with control solution. See Section 5, Control solution testing.
If you are experiencing symptoms that are not consistent with your blood glucose results and you have followed all
instructions in this User Guide, call your healthcare professional. Never ignore symptoms or make significant changes to
your diabetes control program without speaking to your healthcare professional.
CAUTION: Unusual red blood cell count
A hematocrit (percentage of your blood that is red blood cells) that is either very high (above 55%) or very low (below 30%)
can cause false results.
After getting a result
Once you have read your result, you may:
• Review your meter memory by pressing
▼
to enter memory mode, see Section 4, Reviewing past results,
or
• Turn the meter off by removing the test strip.
Removing the used lancet
Remove the lancing device cap by snapping it off.
Cover the exposed lancet tip before removing
the lancet.
Place the lancet protective disk on a hard surface. Push the lancet tip into the disk. Remove
the lancet and place it in a container for sharp objects. Replace the cap.
Disposing of the used lancet and test strip
It is important to discard the used lancet carefully after each use to avoid unintended lancet stick
injuries. Used test strips and lancets may be considered biohazardous waste in your area. Be sure to
follow your local regulations or your healthcare professional's recommendations for proper disposal.
