Interpreting Unexpected Test Results:
Refer to the following cautions whenever your test results are lower or higher than what you expect.
CAUTION:
Low glucose results:
If your test result is lower than 70 mg/dL or is shown as LOW GLUCOSE, it may mean hypoglycemia (low blood glucose). Treat this condition immediately, according to your health care professional’s recommendations. Although this result could be due to a test error, it is safer to treat first, then do another test.
If you test at the low end of the operating range (43°F) and your blood glucose is high, you may get an inaccurate low result. Re-test in a warmer environment with a new test strip.
Dehydration and low glucose results:
You may get false low glucose results if you are severely dehydrated. If you think you are severely dehydrated, contact your health care professional immediately.
High glucose results:
If your test result is higher than 180 mg/dL, it may mean hyperglycemia (high blood glucose) and you should consider re-testing. Talk to your health care professional if you are concerned about hyperglycemia.
HIGH GLUCOSE is displayed when your blood glucose level is higher than 600 mg/dL. You may have severe hyperglycemia (very high blood glucose). Re-test your blood glucose.
If the result is 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 glucose results:
If you continue to get unexpected results, check your system with control solution.
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 health care professional. Never ignore symptoms or make significant changes to your diabetes control 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 55%) or very low (below 30%) can cause false results.
