Unexpected Test Results:

• Refer to these cautions whenever your results are lower than, higher than, or otherwise not what you expect.

• • 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. See articles:

• • 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.
