Interpreting unexpected results:
Refer to the following cautions when your results are higher or lower than what you expect.
CAUTION:
Low results:
If your result is below 4.0 mmol/L or is shown as LO (meaning the result is less than 1.1 mmol/L), 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.
NOTE:
When your glucose result is below 1.1 mmol/L, both the LO and the Range Indicator Arrow will flash on the meter screen.
CAUTION:
Dehydration and low results:
You may get false low results if you are severely dehydrated. If you think you are severely dehydrated, contact your healthcare professional immediately.
CAUTION:
High results:
If your result is above 10.0 mmol/L, it may mean hyperglycemia (high blood glucose) and you should consider re-testing. Talk to your healthcare professional if you are concerned about hyperglycemia.
HI is displayed when your result is over 33.3 mmol/L. You may have severe hyperglycemia (very high blood glucose). Re-test your blood glucose level. If the result is HI again, this indicates a severe problem with your blood glucose control. Obtain and follow instructions from your healthcare professional immediately.
NOTE:
When your glucose result is above 33.3 mmol/L, both the HI and the Range Indicator Arrow will flash on the meter screen.
CAUTION:
Repeated unexpected 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 results and you have followed all instructions in your Owner's Guide, call your healthcare professional. Never ignore symptoms or make significant changes to your diabetes management program without speaking to your healthcare 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.
