Taking a test
m CAUTION
High blood glucose results
EXTREME HIGH GLUCOSE is displayed when your blood
glucose result is over 600 mg/dL. You may have severe
hyperglycemia (very high blood glucose). Re-test your
blood glucose level. If the result is EXTREME HIGH
GLUCOSE again, this indicates a severe problem with your
blood glucose control. Obtain and follow instructions from
your health care professional immediately.
Repeated unexpected blood glucose results
If you continue to get unexpected results, check your
system with control solution. See Control solution testing,
pages 47–54.
If you are experiencing symptoms that are not consistent
with your blood glucose results and you have followed all
instructions in this Owner's Booklet, call your health care
professional. Never ignore symptoms or make significant
changes to your diabetes management program without
speaking to your health care professional.
Unusual red blood cell count
A hematocrit (percentage of your blood that is red blood
cells) that is either very high (above 60%) or very low
(below 20%) can cause false results.
